Description

A kind of fire-retardant high-strength high-ductility acrylic solid slab and preparation method thereof
Technical field
The invention belongs to the composite sheet field, particularly a kind of fire-retardant high-strength high-ductility acrylic solid slab and preparation method thereof.
Background technology
At present, acrylic cabinet plate poor toughness, frangible on the market, acrylic facing plate intensity and difference of hardness, easily scuffing, and cost height.Make uses of can regenerating of discarded acrylic cabinet plate and acrylic facing plate, the cost of reduction acrylic board improves the development trend that its toughness, intensity and hardness are acrylic boards.And acrylic cabinet plate and acrylic facing plate also need the requirement that reaches fire-retardant.
Waste organic glass mainly comes from scrap stock in substandard product, the casting in the moulding process (road) and the mechanical workout in the production, smear metal (sheet) etc., in addition, also has quite a few from the field of circulation, for example, in an automobile of scrapping, the quality of synthetic glass will account for about 30% (except the tires) of non-metallic part.Waste organic glass can adopt modes such as machinery, cracking, incineration to recycle as one of important member in the plastic waste.According to the literature, waste organic glass also dissolves in organic solvent, produces matrix materials such as tackiness agent, acrylic table top, is hydrolyzed to the sodium polymethacrylate that can be used for sewage disposal etc. under alkaline condition.Though waste organic glass thermo-cracking raw material reclaims general, the energy consumption height.It is low that energy consumption is reclaimed in its dissolving, but solvent toxicity is big, and environmental pollution is serious.
Flyash mainly comes from thermal power generation and metallurgical coal fire discharged solid waste, nineteen ninety-five, the flyash quantity discharged reached 1.25 hundred million tons, be about 1.5 hundred million tons in 2000, be about 3.75 hundred million tons in 2009, reached 4.8 hundred million tons in 2010, cause huge pressure for the development of the national economy and the ecotope of China, flyash pollutes has become the maximum single solid pollution source of China.At present, the application potential of flyash in macromolecular material more and more comes into one's own, and the research report mainly is to utilize heat-resisting, the chemical property of flyash to stablize and inexpensive characteristics, makes it serve as the common fillers role.
Wood chip mainly comes from sawdust, wood shavings powder and the waste leftover material that wood working stays, the broken end that waste and old wood is pulverized, and is a kind of of great value renewable resource.Wood chip is the natural composite material that the xylogen by the hemicellulose of the Mierocrystalline cellulose of 50-55%, 15-25% and 20-30% constitutes as major ingredient.Wood chip can directly act as a fuel, or makes industrial chemicals or products such as feed, ethanol, Mierocrystalline cellulose by chemical treatment, or directly produces lignin plastics as filler.
