Abstract

The invention relates to an environmental-friendly hollow brick made from the following raw materials in parts by weight: (1) internal brick body mortar, i.e. 100 parts of cement, 250-350 parts of sand, 50-150 parts of slag, 400-600 parts of water, 10-20 parts of chrysanthemum powder, 10-20 parts of 75 <#> industrial mildewcide, 0.1-0.5 part of early strength agent; and (2) coating sizing agents, i.e. 5-8 parts of gelatin, 2-3 parts of honey, 7-9 parts of glutinous rice flour, 4-6 parts of green bean powder, 2-4 parts of sulphur powder, 1-3 parts of boric acid powder and 20-30 parts of water. The invention also relates to the preparation method of the environmental-friendly hollow brick. The invention has the advantages of simple raw materials, low cost, heat preservation and isolation and long service life; the coating sizing agents are ropy colloids, and soil layer sizing agents form a compact and solid shell after being dried, thereby effectively preventing the vast majority of harmful gas from being separated out; in addition, the chrysanthemum powder is added so that a small amount of the separated gas has fragrant smell, thereby reducing the harm on human bodies.

Description

Hollow brick and preparation method thereof

(1) technical field

The invention belongs to non-burning brick and preparation method thereof, particularly a kind of environmental-friendly hollow brick and preparation method thereof.

(2) background technology

At present, the existing non-burning brick materials such as cement, slag that use more, often contain harmful element in these materials, the building of practical this non-burning brick construction will discharge pernicious gas slowly, especially to the people office or the house of living, can cause very major injury to human body, people's health is caused very big threat.And existing environmental protection brick often cost is higher, can't obtain promoting.The somebody can be in the house brushing environmental protection coating material, so also can increase housing cost.

(3) summary of the invention

The present invention is in order to remedy the deficiencies in the prior art, provides that a kind of raw material is simple, cost is low, can effectively stop environmental-friendly hollow brick that pernicious gas separates out and preparation method thereof, and this preparation method is also very simple, easily operation.

The present invention is achieved through the following technical solutions:

Environmental-friendly hollow brick of the present invention, its special character is: the raw material by following parts by weight is made:

1. inner brick body mortar: 100 parts of cement, sand 250-350 part, slag 50-150 part, water 400-600 part, chrysanthemum powder 10-20 part, 75 ^#Industrial fungicide 10-20 part, early strength admixture 0.1-0.5 part;

2. coating paste: gelatin 5-8 part, honey 2-3 part, glutinous rice flour 7-9 part, mung bean flour 4-6 part, Cosan 2-4 part, boric acid powder 1-3 part, water 20-30 part.

The preparation method of environmental-friendly hollow brick of the present invention, its special character is: made successively by following steps:

1. make inner brick body: in one plane with inner brick body mortar shop, after laying the 30-40 millimeter, be placed with the fuse of certain interval on mortar, continuing then to lay mortar to gross thickness is the 120-160 millimeter, the mortar curing and demolding is taken out fuse, and stripping and slicing obtains inner brick body;

2. make coating: all faces brush one deck coating pastes with inner brick body, repeat again after the drying to whitewash one deck coating paste, dry and get final product.

Because inner brick body can cut into different size as required, therefore the coating paste that uses is how much also different.Have biogum in glutinous rice in the coating paste and the honey, gelatin itself is exactly a biogum, and these biogums are nontoxic.Biogum is a kind of natural polymer macromolecule of biologically active, have extremely strong, absorption affinity, bonding force, extension and penetration, with after other material contacts, the reaction of the heat of hydration of swift and violent diffusion can take place, can be penetrated into the inside of other material, volatilization along with moisture content, produce huge cohesive strength, the material of various unlike materials is linked together securely, form an integral body, increased the intensity of material greatly, rigidity, fracture toughness and density are because the density on surface is strengthened, reduce water absorbing capacity, thereby improved the macro property of material.

The invention has the beneficial effects as follows that raw material is simple, cost is low, thermal insulation, long service life.Coating paste is the colloid of thickness, and the dry and hard back of soil layer slurry forms fine and close firm shell, can effectively stop most pernicious gases to be separated out, because the adding of chrysanthemum powder makes the gas smell fragrance of separating out on a small quantity, has alleviated the injury to human body.
