With the maturing of glass fiber reinforced plastic basic research technology and the continuous introduction of advanced foreign equipment and technology, the domestic glass steel industry has developed rapidly in recent years, and the varieties of gel coat resins have been continuously expanding. The continuous improvement in the variety and performance of gel coat resins has led to a continuous expansion of their application fields. Currently, gel coat resins are used in sanitary ware such as shower trays, bathtubs, and countertops, shipbuilding industries such as yachts, life boats, patrol boats, etc., and transportation. Industry, construction, entertainment, medical instrument housings, billboards, telephone booths and security kiosks are used in many fields. The gel coat resin is divided into unpainted gel coat and colored gel coat. In the production process, most cases require the use of colored gel coats. In the past, color gel coat was made by adding appropriate amount of color paste (also known as pigment paste) to the artificial gel coat. The color paste thus prepared was assembled in large-scale assembly products such as cooling towers or large-volume products such as sports fields. The production process of the seats on the viewing table often causes chromatic aberration and seriously affects the appearance of the products. In order to overcome this drawback and improve the appearance quality of products, it is necessary to produce colorless gel coats that are colorless for customers. The research and development of low-styrene sporadic gel coat resin is very necessary and of great practical significance. At present, many new gel coat resins have been developed abroad.
At present, there are not many enterprises that can produce colored gel coats in China. Ashland Polyester (Kunshan) Co., Ltd. is the largest supplier of colored gel coats in China. Ashland has provided faster and more timely services to gel coat customers. , In the world (including Ashland Polyester (Kunshan) Co., Ltd.) launched the INSTINT rapid gel coat production system, which can produce color glue of the desired color in a few minutes; Jinling DSM from DSM The headquarters (having the world's largest gel coat factory) introduces the world's most advanced full-automatic computerized and color-matching Eurotinter equipment, which is the world's fifth largest colored gel coat, with an annual output of 1,000 tons. Production line; Jiangsu Fuling Chemical Co., Ltd. (formerly Jiangsu Fuli Chemicals) also imported an advanced computerized color matching gelcoat production line from the Netherlands; a state-owned large-scale enterprise Tianma Group (the domestic glass steel industry has a greater influence) and Italy Chemicals (Taiwan's largest gel coat factory, one of the major gel coat suppliers in Southeast Asia up to Asia, and a Taiwan-owned company) Color matching system for colored gel coats The most advanced computer color, then by personnel color, can eliminate chromatic aberration due to the maximum extent paste different batches brings. The characteristic color gel coat produced by the Bei’anhe FRP factory is the one who dominates.
The matrix of gel coat resin is unsaturated polyester resin (UP), so most of the companies that produce UP produce gel coat resin. According to incomplete statistics, in 2001, the annual sales volume of gel coat in China was about 20,000 tons, including color More than 3,000 tons of gel coat. In recent years, the annual sales volume of gel coats of various companies has increased by 10% to 30%, and the growth rate has not diminished. This shows that the gel coat market has great potential. Although the market prospects are very good, the competition is still very fierce, we must gain a firm foothold in the industry, need to have sufficient economic strength to occupy the market with high quality and low price, or have a unique product, the annual sales volume of the plastic clothing of Bei’anhe FRP Factory. Although it is not too big, it possesses air-dried gel coats, radiation-cured gel coats, and unbreakable mold gel coats and other specialty gel coats. It has a leading position in the industry and its profits are still considerable; SMC colorant can withstand high temperature 180°C and the surface of the product is colorless. It has been successfully applied to large central air conditioners. Gel coat resin is a special resin for making gel coat layers of glass steel products. Styrene is still the most suitable monomer for current UP resins. However, styrene has a high vapor pressure at room temperature and is easily volatilized. In particular, a glass fiber reinforced plastic product produced by hand lay-up or injection molding process is more volatile in its gel coat layer and backing reinforcing layer.
