A kind of wall heat insulation material
Technical field
The invention belongs to building material field, be specifically related to a kind of wall heat insulation material.
Background technology
Along with the fast development of industry, Economic development is also quite rapid, the whole world is also increasing to the demand of the energy, in the total energy day by day increased consumes, building energy consumption is large especially, account for that total energy consumes 11 ~ 25%, a large amount of data and experiment all show that the fastest most effective means uses heat insulating energy saving material exactly.
Now at home and abroad, very eurypalynous lagging material is had.By material classification, lagging material can be divided three classes: metal heat preservation material, organic insulation material, inorganic heat insulation material.
But the source of goods of metal heat preservation material this material is little, expensive, and the lagging material as building can raise the cost widely, can not apply widely.
Organic insulation material is easy to burning, easily produces poisonous gas when high temperature, ageing-resistant, resistivity against fire is poor, these shortcomings all limit the use widely of organic insulation material.
The pearlstone of China probably has the output of about 6,000,000 tons every year.But traditional pearlstone is a kind of material of honeycomb structure, there are many holes, crack in its surface and inside, such vesicular structure just result in the friability of pearlstone, the stability of density is also very poor, the defect that the compression ratio of goods in the course of processing is very large, this defect can make the lightweight of expanded perlite product and heat insulation effect all can decline, and according to the requirement of lagging material, material needs to have certain intensity.
Another fatal defects perlitic is the material that water-absorbent is very strong, this is the vesicular structure due to pearlstone, and be a kind of result of perforate, and there is adsorptivity, sky G&W is freed in and out, and after it soaks 25 hours in water, its water-intake rate gets back to about 5 times of own wt, this shortcoming will affect the heat-insulating property of expanded perlite product and permanent suitability widely, also can increase the oven dry cost of expanded perlite product.
Summary of the invention
The object of this invention is to provide a kind of wall heat insulation material and preparation method thereof, to make up the deficiencies in the prior art.
A kind of wall heat insulation material, described wall heat insulation material comprises following component: coating pearlstone 100 ~ 150 parts, drift 30 ~ 100 parts, pearl, cement 30 ~ 50 parts, permeate agent 3 ~ 15 parts, hydrophober 3 ~ 15 parts, binding agent 3 ~ 15 parts, exciting agent 3 ~ 15 parts.
Described coating pearlstone obtains in the following manner:
(1) get 100 object pearlstones, join in seed-coating machine and be heated to 200 ~ 250 DEG C, and add calcium carbonate powders, stir, wherein the mass ratio of pearlstone and calcium carbonate powders is 100:5;
(2) then pearlstone soaks by seed-coating machine one end sprinkling distilled water, and epoxy resin powder is sprayed in one end, and constantly stirs 20 ~ 40min, obtains coating pearlstone.
The production technique of described wall heat insulation material comprises the steps:
(1) take coating pearlstone according to described proportioning, drift pearl, cement, permeate agent, hydrophober, binding agent, exciting agent put into stirrer and mix and stir;
(2) in said mixture, add distilled water, continue stirring 30 ~ 60min with stirrer;
(3) above-mentioned slurry is poured in mould use press-forming machine compression moulding, last natural curing 24h, obtain described vitrified small ball wall lagging material.
Further, step adds distilled water described in (2), and wherein ratio of water to material is 0.40 ~ 0.55:1.
Further, the pressure setting of step (3) described compression moulding is 0.80 ~ 0.85MPa.
Further, the press time of step (3) described compression moulding is set as 10 ~ 30min.
Further, step (3) described mould is of a size of 1200mm × 600mm × 50mm.
Described wall heat insulation material is by carrying out coating to pearlstone, take full advantage of pearlstone fire-resistant, insulation, lasting, corrosion resistant advantage, reduce the shortcoming of the easy water-swelling of pearlstone, therefore this wall heat insulation material is compared with traditional wall heat insulation material, heat-insulating property better, more lastingly, and meets the requirement of National Fire A level.
