Manufacture method for flame-retardant heat-insulation acrylic sheet

Abstract

The invention relates to a manufacture method for a flame-retardant heat-insulation acrylic sheet. The flame-retardant heat-insulation acrylic sheet provided by the invention is manufactured from the following raw materials in a proportion by weight: 100 g of organic glass prepolymer, 60-80 g of wastes generated from a heat power plant, 0-5 g of a coloring pigment, 20-30 g of a flame retardant and 0.4-0.6 g of an antifoaming agent through mixing and pouring polymerization. The flame-retardant heat-insulation acrylic sheet provided by the invention has a heat-insulation temperature difference of 15-25 DEG C and a burning scale of FH-3-15 mm / min, and has the characteristics of diverse colors, high surface hardness and glossiness, light weight, easiness in shaping processing and good flame-retardant and heat-insulation effects; and the manufacture method provided by the invention can increase the utilization rate of wastes, reduce environmental pollution and lower production cost, and the flame-retardant heat-insulation acrylic sheet provided by the invention can be widely applied in building and house decoration industries.

Description

technical field

[0001] The invention belongs to plastic casting plates, in particular to a preparation method of a flame-retardant and heat-insulating acrylic plate. Background technique

[0002] In the 1970s, the global energy crisis, environmental pollution and the depletion of mineral resources strongly stimulated the research and development of fly ash utilization, and the resource utilization of fly ash has always been a matter of great concern to governments, experts and scholars all over the world. , Fly ash has become an eye-catching new building material raw material and chemical product raw material in the international market, which is rich in resources, low in price, and beneficial in eliminating harm. According to relevant data, the total stock of fly ash discharged in China has exceeded 1 billion tons, and it is increasing at a rate of 120 million tons per year. On September 15, 2010, the international environmental protection organization Greenpeace released ...
