Abstract
The present invention relates to heat insulating materials of light wall bodies, which are prepared by the following ingredients according to the following proportions: 25 to 60% of pulverized coal ash, 10 to 20% of perlite or vermiculites, 0 to 10% of water glass, 0 to 10% of organic silicon and 20 to 40% of waste plastic emulsion. Final products are divided into paste form coating mixtures with indefinite forms and plate-shaped forming materials. The heat insulating materials have the advantages of good heat insulating property, incombustibility, water resistance, simple manufacturing technique, wide raw material source and low cost. The heat insulating materials offer a new purpose to pulverized coal ash, which is beneficial for environmental protection.
Description
The present invention relates to a kind of thermal insulation material, particularly a kind of lightweight wall plate thermal insulation material.
Existing wall plate thermal insulation material mainly contains following three kinds:
1, manmade inorganic fibre thermal insulation material: commonly used have block of glass wool or a rock cotton board, and this material ultimate compression strength is low, and human body is had stimulation, has prodding and itching feeling during construction.Need to use the other materials mask infiltration of difficult anti-rainwater when being used for exterior wall after the construction.
2, organic materials foaming plate: commonly used has the polyethylene of foaming plate and the polystyrene plate that foams, and this material can not be prevented fires, and intensity is also little, and price is higher.
3, cement perlite plate: this material unit weight is big, and thermal conductivity is big, and heat-insulating property is not good, and property is crisp, and breakage rate is big during the transportation construction.
More than three kinds of materials all have in various degree shortcoming, be difficult to common promoting the use of.Therefore, seek new better wall plate thermal insulation material, be the target that people seek assiduously always.
At present, the quantity discharged of the annual flyash in fuel-burning power plant has about 100,000,000 tons, need take and stack 300,000 mu in place, serious appropriation of land and contaminate environment.Therefore, how flyash is effectively utilized, also troubling people always.
Purpose of the present invention is exactly to be the heat-insulating property lightweight wall plate thermal insulation material preferably of main raw material with flyash for people provide a kind of.
Principle of the present invention is: utilize the fly ash grain major part to be cavernous honeycomb, have this characteristic of very little tap density, be aided with perlite or vermiculite and binding agent, optionally add toughener, water-repellent agent etc. again, promptly can be made into material with fine heat-insulating property.
Above-mentioned each proportion of raw materials is: flyash: 25-60%, stopping composition: perlite or vermiculite 10-20%, toughener: water glass 0-10%, water-repellent agent: organosilicon 0-10%, binding agent: plastic waste emulsion 20-40%.
Finished product of the present invention has two kinds of forms: the paste coating of indefinite form and tabular shaping material.External wall of house and roofing can be used the sheet profile sticking construction, indoorly then can directly smear with the indefinite form paste material, and can save the cement sand plaster layer, save construction costs.
The present invention has following advantage:
1, good heat insulating is not fired, water-fast;
2, manufacturing process is simple, and raw material sources are extensive, and cost is low;
3, for flyash provides a new purposes, help environmental protection.
The invention will be further described below in conjunction with embodiment.
Embodiment one: the paste coating of production indefinite form
Getting flyash 40 grams (calculates with butt, as follows), stopping composition perlite 15 gram, both are mixed the back add in the oar formula mixer and stir, add binding agent plastic waste emulsion 30 grams simultaneously, stirred about 10 minutes, after making the even wetting material of binding agent, add toughener water glass 7 grams and water-repellent agent organosilicon 8 grams again, continue to stir, add an amount of water while stirring, the 3-6 that is generally above-mentioned raw materials doubly when blended stock stirs into paste, promptly makes finished product.
Embodiment two: produce tabular shaping material
Get flyash 60 grams, stopping composition vermiculite 10 grams, both are mixed back the adding in the oar formula mixer stirs, add binding agent plastic waste emulsion 20 grams simultaneously, stirred about 10 minutes, after making the even wetting material of binding agent, add toughener water glass 10 grams again, continue to stir, add an amount of water, be generally 1-3 times of above-mentioned raw materials while stir, compound can be agglomerating in the mixer when hand is pinched, when unclamping hand and not scattering, compound can be taken out from mixer, pour compacting in the shaping mould into, dry after the demoulding, can make finished product.
The binding agent that above-mentioned two embodiment are adopted is the used foam plastics emulsion, and available ordinary method is made.As: after used foam plastics usefulness solvent such as toluene dissolving, add emulsifier solution such as peregal, at the mulser internal emulsification.Certainly, also can adopt other plastic waste, make emulsion as useless polyvinyl chloride.
Claims (2)
1, a kind of lightweight wall plate thermal insulation material is characterized in that it is prepared from following ratio by following component: flyash 25-60%, perlite or vermiculite 10-20%, water glass 0-10%, organosilicon 0-10%, plastic waste emulsion 20-40%.
2, lightweight wall plate thermal insulation material as claimed in claim 1 is characterized in that described plastic waste emulsion is the used foam plastics emulsion.
