Abstract
The invention discloses a high-elasticity silica aerogel polyurethane composite thermal insulation wall board prepared from the following raw materials in parts by weight: 1.3-1.5 parts of urotropine, 3-3.5 parts of E-12 epoxy resin, 0.8-1.1 parts of sodium carboxymethylcellulose, 3-3.5 parts of a latex powder, 100-105 parts of porous ceramic balls, 100 parts of water glass, a proper amount of Span-80, a proper amount of Tween-80, a proper amount of 1 mol/L ammonia water, a proper amount of acetone, a proper amount of ethanol, 90-94 parts of polyether polyol DSU-365, 0.5-0.54 part of triethanolamine, 15-16 parts of water, 0.75-0.9 part of dibutyltin dilaurate, and 100-110 parts of polyaryl polymethylene isocyanate. Through the use of the urotropine, E-12 epoxy resin, sodium carboxymethylcellulose and latex powder, silica aerogel is sealed in the ceramic balls, so as to prevent aerogel breaking and improve heat insulation and rebound resilience.
Description
Technical field
The present invention relates to heat-insulation wall plate technical field, particularly relate to a kind of high resiliency aerosil polyurethane composite thermal insulation wallboard and preparation method thereof.
Background technology
Polystyrene board is a kind of common insulation material for building.Its density is low, mechanical strength segmentation good, corrosion-resistant, waterproof, easy construction, but its heat conductivity of a relatively high (k ≈ 0.042W/m K).The characteristic such as the nano-porous structure of silica aerogel and ultralight, superadiabatic, extremely strong uv absorption, infrared external reflection significantly limit conduction of heat and the thermal convection current of heat transfer process.With SiO2Aeroge/polystyrene type composite construction can reduce the heat conductivity of EPS warming plate further, improves the fire resistance of EPS warming plate under conditions of not affecting EPS sheet mechanical property.Meanwhile, the two is combined can effectively make up the shortcoming that silica aerogel structural strength in actual applications is low, hydrophilic, reduces heat conductivity simultaneously, improves its fire resistance.《SiO2Aeroge core/polystyrene shell composite flame-proof warming plate experimentation " use heat pressing dipping method that foaming agent immerses compound beadlet, thus obtain the SiO of expansion type2Aeroge core/polystyrene shell mould is combined beadlet, studies its foaming processing technology with steam foaming simultaneously.
But the insulation material that the method obtains is because of SiO2Aeroge is easily broken and heat-insulating property can not be continual and steady.The toughness of this insulation material, thermostability, resistance to water, heat generation, static electricity resistance, mildew resistance, antibiotic property, intensity, resilience, ageing resistance, corrosion resistance all have much room for improvement simultaneously.Polyurethane foam has the heat-insulating property of excellence, but not as SiO2Aeroge good heat preservation performance, but anti-flammability is bad.
Fire-retardant and excellent in mechanical performance polyurethane foam prepared in " preparation of full water foamed hard polyurethane foam and the research of fire resistance thereof " literary composition, but heat-insulating property still can not meet the needs of scientific development.
If by SiO2Aeroge is combined with polyurethane foam, it is possible to increase the heat insulating ability of polyurethane foam and anti-flammability, but direct combination, SiO2Aeroge is easily broken, heat insulation effect evanescence, requires further improvement.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of high resiliency aerosil polyurethane composite thermal insulation wallboard and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of high resiliency aerosil polyurethane composite thermal insulation wallboard, is prepared by the raw materials in: hexamethylenamine 1.3-1.5, E-12 epoxy resin 3-3.5, sodium carboxymethyl cellulose 0.8-1.1, latex powder 3-3.5, porous ceramic ball 100-105, waterglass 100, Span-80 is appropriate, Tween-80 is appropriate, 1mol/L ammonia in right amount, acetone in proper, appropriate amount of ethanol, polyether polyol DSU-365 90-94, triethanolamine 0.5-0.54, water 15-16, dibutyl tin laurate 0.75-0.9, poly methylene poly phenyl poly isocyanate 100-110.
The preparation method of described high resiliency aerosil polyurethane composite thermal insulation wallboard, comprises the following steps:
(1) VSpan-80:VTween-80=1:4 proportioning obtains mixing liquid by volume, is mixed homogeneously with described mixing liquid 1:10 by volume by waterglass, stirs 30min under 400r/min, and the ammonia then dripping 1mol/L regulates pH value to 6-7；Adding porous ceramics microsphere, E-12 epoxy resin, stir 10-15min, with washing with acetone 2-3 time, after standing, the removing supernatant, obtains mixed material；
