Description
Technical field
The present invention relates to building material technique, in particular a kind of preparation method of light flyash heat insulating decorative board.
Background technology
Flyash is mainly by CaO, SiO
2, Al
2o
3form Deng oxide compound, there is the value of higher industry recycling.The thin ash 90% of the flyash produced during Hanzhong Xin Ye limited liability company produces all more than 200 orders, after screening and surface modification treatment, can interface cohesion good with resin formation, can be used for Development and Production flyash-resin compounded sheet material.This sheet material can be used for the fields such as laying floor, inner wall decoration, body of wall sound-insulating layer, can not only bring considerable economic benefit, and accumulation pollution problem flyash can also avoided not utilize completely and cause, and produces good social benefit.
Existing utilization of fly ash technology mainly concentrates on the fields such as building, agricultural, chemical industry, sewage disposal, the technology content of great majority application is not high, and the technology that some technology contents are higher, because application cost is high, technical process is complicated and can not be applied widely.
Summary of the invention
Technical problem to be solved by this invention is the preparation method providing a kind of light flyash heat insulating decorative board for the deficiencies in the prior art.
Technical scheme of the present invention is as follows:
A preparation method for light flyash heat insulating decorative board, comprises the following steps:
The surface modification of flyash: get 1000 weight part 200 object flyash for subsequent use, then after getting the dehydrated alcohol dilution of the weight such as the tetramethoxy-silicane use of 50 ~ 100 weight parts, evenly be added drop-wise in flyash in well-beaten situation, after flyash is fully flooded, be placed in the loft drier fully drying for standby of 60 ~ 80 DEG C;
The configuration of flyash-epoxy resin slurry: in the mixing container by 1000 parts by weight epoxy resin, fully be dissolved in 100 ~ 200 pbw acetone, then 60 ~ 80 weight part quadrols are added, add the coal ash of 800 ~ 1200 weight parts after surface modification after stirring, stir rear for subsequent use;
Light flyash heat insulating decorative board shaping: the flyash-epoxy resin slurry configured is injected mould, heating is stopped after mould being placed in the loft drier heating 10 ~ 40min of 60 ~ 80 DEG C, after case naturally cooling to be dried, product is taken out from mould and obtains light flyash heat insulating decorative board.
Light flyash heat insulating decorative board of the present invention has the outstanding features such as thermal insulation is good, porous light, surface hardness are high, and its thermal conductivity≤0.08W/ (m.K), density is 0.48g/cm
3left and right, surperficial shore hardness>=75 degree.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
1. material, reagent and equipment
1) material used, reagent are as follows:
Flyash, carefully ash, Hanzhong Xin Ye limited-liability company;
Epoxy resin (EP), E-44, Xi'an Kodak tackiness agent company limited;

2, the preparation method of light flyash heat insulating decorative board
The screening of flyash and surface modification: flyash Vibration Screen being selected fineness 200 object flyash is starting material.Get 1000g flyash for subsequent use, then after getting the dehydrated alcohol dilution of the tetramethoxy-silicane equivalent of about 50 ~ 100g, evenly be added drop-wise in flyash in well-beaten situation, treat that flyash is fully flooded and be placed on abundant drying for standby in the loft drier of 60 ~ 80 DEG C.Flyash, after surface modification treatment, can form stable interface cohesion with resin matrix.
The configuration of flyash-epoxy resin slurry: in the mixing container by 1000g epoxy resin (resin matrix, play fly adhesives, increase the effect of shaping mobility) be fully dissolved in 100 ~ 200g acetone (solvent, mention shaping mobility) in, then 60 ~ 80g quadrol (or diethylenetriamine solidifying agent is added, cause the curing reaction reaction of resin matrix), the 200 order flyash (fillers of 800 ~ 1200g after surface modification are added after stirring, reduce costs, improve thermotolerance, gain in strength and rigidity, solid waste utilizes), stir rear for subsequent use.The pigment that can also add about 5 ~ 8wt% in the feed carries out painted, forms the heat insulating decorative board of various color.
Light flyash heat insulating decorative board shaping: paste layer of plastic film at molding die surface, flyash-epoxy resin the slurry configured is injected mould, heating is stopped after mould being placed in the loft drier heating 10 ~ 40min of 60 ~ 80 DEG C, after case naturally cooling to be dried, product is taken out from mould and obtains light flyash heat insulating decorative board.The wall covering surface surface irregularity of laboratory sample is beneficial to and forms firmly interface cohesion with body of wall.
Light flyash heat insulating decorative board of the present invention has the outstanding features such as thermal insulation is good, porous light, surface hardness are high, and its thermal conductivity≤0.08W/ (m.K), density is 0.48g/cm
3left and right, surperficial shore hardness>=75 degree.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
