Description
Technical field
The present invention relates to foam thermal insulation composite-material formula and preparing technical field, particularly a kind of unsaturated polyester resin foam thermal insulation matrix material and preparation method thereof.
Background technology
Along with China's rapid development of economy, energy starved problem becomes increasingly conspicuous, an energy-conservation important fundamental state policy that has become China.In various energy starved problems, comparatively outstanding is that heating buildings energy consumption is higher, the problem that energy dissipation is comparatively serious.Country has proposed energy-conservation 50% compulsory standard for Building Energy-saving, increasing place starts to carry out the compulsory standard of building energy conservation 65%.2011, China has proposed new standard for building thermal insulation material, the floors of the partition wall of staircase partition wall, the public building heating subregion of regulation covil construction, the elevator raise wall of Highrise buildings, residential architecture party wall, floor thermal radiation heating etc., all should adopt A level lagging material to improve its insulation, heat insulation and flame retardant properties.
The lagging material of use is broadly divided into inorganic heat insulation material and organic insulation material two classes in the market, inorganic heat insulation material mainly contains rock wool, glass wool, pearlstone, foamed concrete etc., it is low that these materials have price, this is as non-fire material, the good advantage of cohesiveness with body of wall, but also to have density large simultaneously, heat insulation property is poor, lay large compared with thick material waste, water absorbability is high, the shortcoming that poor seismic behavior and environmental-protecting performance are poor, therefore, use these inorganic heat insulation materials often cannot reach energy conservation standard, and the building thermal insulation material such as asbestos or glass wool itself is all with a large amount of objectionable impuritiess, cannot meet people's health requirements.Organic insulation material mainly contains polystyrene foam, polyurethane foam and phenolic resin foam three major types, polystyrene foam because of its price having compared with the advantage such as low, heat insulation property is good, water-absorbent is little, water vapour permeability is low, impact-absorbing is good by a large number for building thermal insulation material field, but the flame retardant resistance of himself is poor, therefore, all trades and professions are used gradually few in recent years; Polyurethane foam is one of best lagging material of heat-proof quality, also have advantages of and do not absorb water simultaneously, but its price is comparatively expensive, the flame retardant resistance of self is also poor, and can discharge a large amount of toxic gases when burning.In Beijing CCTV fire of recurring in recent years, Nanjing, encircle International Square fire, the special fire disaster of Jiangzhou road, Shanghai apartment building " 1115 ", Shenyang feudal dynasty Wan Xin mansion big fire, Olympic Sports Center Gymnasium, Jinan fire, Gemini mansion, Harbin " longitude and latitude 360 is spent " fire, post-survey arch-criminal is urethane or polystyrene type lagging material.Phenolic resin foam has the advantages that not need to add fire retardant and just have good fire resistance, when its burning, toxicity is very little, American-European a lot of country has extensively adopted phenolic resin foam at present, but there is the problem that has formaldehyde volatilization under comparatively high temps in phenolic resin foam, and phenolic resin foam production cost is higher.
