CN1149608A - New building water-proof daubing agent - Google Patents

Abstract

The invented daubling agent consists of 20-50% of propenoic acid emulsion, 4-10% of vinol, 3-8% of thickening agent, 10-20% of titanium dioxide powder, 5-10% of gypsum powder, 5-15% of whiting powder, 6-8% of talc powder and bentonite. The invented daubling agent features good properties of waterproof, protection, film-forming and water-isolation, toxicless, not polluting environment, not limmited by the building basal body, environment and color etc., firm cohesion, and long life. It not only can be used for stopping-leak and waterproof, but also can be used to bind ceramic tile, marble, etc. articles and it is also suitable for antirusting of metal and for antierosin and anti-moth-eaten of wooden articles.

Description

A kind of new building water-proof daubing agent

The invention relates to a kind of waterproof agent for building, more particularly about a kind of new building water-proof daubing agent.

In the prior art, various in style about the finishing agent of buildings waterproof.Usually they all are the chloroprene latex bitumens by liquid or solid pitch and modification, the coiled material that rubber asphalt and these materials are made, and these materials are not only poisonous, inflammable, contaminate environment, constructional difficulties, waterproof plugging leaks are also not ideal.Product of the present invention is completely different with these products, and these prior aries have obvious difference completely with the present invention in starting material and preparation.

The object of the present invention is to provide a kind of building water-proof daubing agent.

Second purpose of the present invention is to provide the corrosion protection of a kind of metal rust preventing, woodwork, mothproof finishing agent.

These and other objects of the present invention will further embody and illustrate by following detailed description.

Building water-proof daubing agent (weight) comprising in the present invention:

20～50% ACRYLIC EMULSION, 4～10% polyvinyl alcohol

30～8% thickening materials, 0.1～10% glycerol

0.5～1% formaldehyde 0.2～0.5% defoamer

10～20% titanium dioxides, 5～10% terra albas

5～15% chalk powders, 6～8% talcum powder

Surplus is a wilkinite.

Further, waterproof finish agent of the present invention comprises:

40% ACRYLIC EMULSION, 7% polyvinyl alcohol

3% thickening material, 0.5% formaldehyde

1% glycerol, 0.5% defoamer

20% titanium dioxide, 5% terra alba

10% chalk powder, 8% talcum powder

5% wilkinite.

Among the present invention, all per-cents all are weight percentage, and all raw material glycerol, formaldehyde, polyvinyl alcohol or the like all can have been bought from the market.ACRYLIC EMULSION can be buied from the Dongfang Chemical Plant, Beijing, The East Chemical Plant,Beijing, and defoamer and thickening material are that chemical industry is commonly used, can be CMC, nitrocotton etc. as thickening material.

Being applied as directly of product of the present invention smeared, and measures the amount doesn't matterly, decides on situation on the spot.

Waterproof finish agent of the present invention prepares as follows:

At first in reactor, add entry; the water yield is 8～9 times of polyvinyl alcohol weight; heat up then; be warming up to more than 90 ℃, add polyvinyl alcohol, make alcohol change into liquid; add thickening material then; ceaselessly stir and make it evenly to become thick slightly liquid, reduce to normal temperature then, in reactor, add glycerol; low speed 40～90rpm stirred 20～40 minutes behind the formaldehyde; add the vinylformic acid synthetic emulsion then; 100～200 rotating speeds stirred 20 minutes, and low speed 50 changes the adding titanium dioxide; terra alba; chalk powder; talcum powder; wilkinite etc., speed-raising 100～200 was changeed 20 minutes; shut down; put into shredder and grind, be ground to pasty state 120 orders, get product.

Dosage is decided as required; product is applicable to metal rust preventing; and woodwork corrosion protection, mothproof etc.; formula for a product of the present invention is reasonable, technology simple, easy operation control; constant product quality; have good especially water-repellancy and protectiveness, and film forming properties is good, water-resisting property is strong, nontoxic, cohesive strength is high, fire-retardant, heat-resisting, oil resistant, water-fast.

Example 1:

Claim all compositions by following proportioning:

Vinylformic acid synthetic emulsion: 40Kg

Polyvinyl alcohol (99): 7Kg

Thickening material (CMC): 3Kg

Formaldehyde: 0.5Kg

Glycerol: 1Kg

Defoamer: 0.5Kg

Titanium dioxide; 20Kg

Terra alba: 5Kg

Chalk powder: 10Kg

Talcum powder; 8Kg

Wilkinite 5Kg

The deionized water that at first in reactor, adds 63Kg, be warming up to 90 ℃ then, add polyvinyl alcohol, make alcohol turn to liquid, add CMC then, do not stop stirring and make it to become liquid, reduce to normal temperature then, add glycerol, formaldehyde again, stirred 40 minutes at 50rpm, add the vinylformic acid synthetic emulsion then, 120rpm stirred 20 minutes down, be decelerated to 50rpm and add other material, raising speed stirred 20 minutes to 130rpm, moved people's shredder and ground, be ground to 120 orders and be finished product, the finished product solid content is 45%.
