New technology for environmentally friendly adhesives: A major breakthrough in China’s adhesive production technology (For more information, please visit: http://www.lkxtg.com). As of July 1, 2002, the production and sale of adhesives containing benzene and formaldehyde will be prohibited. This product has been recognized by the relevant authorities as part of the first batch of “Reputable Brands of Environmentally Friendly Products in China”; it meets the mandatory standards (CB18583-2001) that came into effect on July 1, 2002. 　　As tested by the **Chemical Building Materials Testing Center, the Chinese Academy of Preventive Medicine, and the Beijing Rubber Industry Research and Design Institute under the Ministry of Chemical Industry, the product contains absolutely no neoprene or benzene-based solvents. It is produced by mixing at normal temperature and pressure for three hours; it features a high solid content, high initial viscosity, and high strength. The amount of adhesive required is 10% less than that of traditional universal adhesives. ? I. Project Overview: ? 　　With the rapid development of economic construction in both urban and rural areas in our country and the continuous improvement of people’s living standards, most people now lead prosperous lives, which has led to higher expectations regarding the quality of their housing. Especially in the decoration and renovation industry, traditional universal adhesives made from neoprene and benzene-based solvents will be phased out gradually, as the slow release of toxic substances they contain poses a direct threat to human health. What will take its place is an environmentally friendly universal adhesive. A recent survey on indoor air quality conducted by the Tianjin Health and Disease Prevention Center showed that in nearly 30,000 square meters of newly built or recently renovated buildings, including kindergartens, office buildings, and residential homes, almost 70% of the indoor spaces in these buildings were affected by chemical pollution; the pass rate for meeting quality standards was only 34.7%. In homes with poor indoor air quality, pollutants such as benzene and formaldehyde are the most severe. The highest is even more than **62.8 times the standard. According to modern medicine, benzene and formaldehyde have been identified as carcinogens and major causes of leukemia, acting as hidden killers that threaten human life. Therefore, in order to protect consumers' health and reduce indoor and outdoor pollution. The \"Standards for Limits of Hazardous Substances in Interior Building Decoration Materials\" formulated by the General Administration of Quality Supervision, Inspection and Quarantine were issued on January 1, 2002, with a six-month transition period; starting from July 1, 2002, products that do not meet these standards were no longer allowed to be sold on the market. These include 102 mandatory **standards** for interior building decoration and finishing, such as engineered wood, interior wall coatings, wood finishes, adhesives, carpets, wallpaper, furniture, and radioactive substances in building materials. The \"Indoor Air Quality Evaluation Standards\" formulated by the **General Administration for Quality Supervision, Inspection and Quarantine**, the **Environmental Protection Administration**, and the Ministry of Health will be released soon. 　　Currently, in the domestic building materials and decoration market, there is a wide range of adhesive products from various brands, with prices varying greatly. Among these, white latex and universal glue are the most widely sold and commonly used. However, white latex has a slow drying time, making it difficult to ensure continuity in construction, and thus it cannot meet the requirements of projects that demand both quality and speed. Therefore, super glue has rapidly captured the decorative finishing market due to its fast drying time, high strength, and ease of use, becoming the undisputed favorite in this field. However, most of the superglues available on the market are produced by foreign-funded enterprises, resulting in high production costs and prices. The superglues manufactured by domestic companies are mainly made from neoprene (the price of neoprene raw materials has been rising in recent years), and it takes 17 to 20 hours from the start of production to the completion of the product, which not only wastes labor and energy but also contains large amounts of benzene-based solvents; as a result, the premises cannot be occupied for several months after renovation. In light of this, the Adhesive Expert Group of the China Association of Senior Scientists and Engineers collected relevant domestic and international literature on adhesives in response to market demands. After hundreds of scientific experiments, they successfully developed \"Jiaowang\" – a fifth-generation, new type of environmentally friendly universal adhesive. Its technology is at the leading level in China, providing domestic enterprises with an opportunity to gain market share. By addressing the shortcomings of traditional universal adhesives through a scientific formula, this product not only reduces costs but also improves quality. ? II. Technical features of the product: ? The eco-friendly universal adhesive produced using this technology contains absolutely no chloroprene raw materials or benzene-based solvents. The solid content is 30–40%, and the tensile shear strength can be adjusted between 6–2.8 MPa. The product is an orange-yellow or slightly yellow viscous liquid. The production process is simple: no heating or pressure is required; it is simply mixed at room temperature, and the product is ready after three hours. The raw materials are available in various locations. There is no emission of waste gases, wastewater, or solid waste during the production process, and no special requirements are imposed on the factory buildings or the environment. The product features fast drying time, high strength, resistance to high and low temperatures, non-gelation, and good water resistance. It is widely used for bonding various materials such as shoes, leather, canvas, rubber, building materials, wood, decorations, finishes, metals, glass, and plastics. Once launched on the market, this product will quickly replace traditional universal adhesives. ? III. Production conditions and profit analysis: ? 1. Annual production capacity of 100 tons; equipment investment of 4,000 yuan; factory space of 40 m2; 2–3 production workers; working capital of 10,000 yuan. One mixer (self-made), one platform scale, and various measuring instruments. ? 2. Annual production capacity: 300 tons; equipment investment: 10,000 yuan; factory space: 80 m2; number of production workers: 4–8; working capital: 30,000 yuan. One 300-liter reactor, various measuring instruments. 3. Annual production capacity of 1,000 tons; equipment investment of 30,000 yuan; factory space of 400 m²; 15 production workers; working capital of 80,000 yuan; 1 reactor with a capacity of 500 liters. Various measuring instruments. ? 4. Existing chemical plants, adhesive factories, and paint factories can carry out production without the need to add any equipment. 5. The cost of the product is 5 yuan/kg to 6 yuan/kg (the cost and solid content can be adjusted as needed); the market price is 10 to 12 yuan/kg. (Currently, environmentally friendly universal adhesives available on the market come in 3-liter containers, with a actual weight of around 2.4 kilograms, and their price is 30 to 50 yuan per container.) At a production capacity of 300 tons per year, with a profit of 5 yuan per kilogram, the annual profit would be 300×1000×5 = 1.5 million yuan. ? IV. Technical service methods and costs: ? 1. Provide the delivery facility with formulas, process procedures, staff training, and copies of quality inspection reports. ? 2. Training fees for technology transfer: 16,000 yuan. 3. Arrange the green label certification on behalf of the party carrying out the delivery, as well as obtain test reports from the **Chemical Building Materials Testing Center and the **Environmental Testing Center (the costs are to be borne by the client). 　 　 Copyright © Beijing Huaxia Keyuan Technology Development Center, 2006.
