Abstract

A water-proof additive for building material is prepared from hydrated lime, stearic acid, ferrous sulfate, aluminium hydroxide, copper sulfate, alum, high-strength gypsum, and animal fat.

Description

The material of construction waterproof additive

Technical field:

The present invention relates to a kind of material of construction, especially relate to a kind of concrete waterproof additive.

Background technology:

At present, leakage of building is increasingly extensive, and the trend that grows in intensity arranged, cause the reason of this phenomenon that many reasons such as material of construction, management, design, construction are arranged, but with in the concrete there is not the fine waterproof additive relevant yet, existing concrete additive is of a great variety, is divided into organically, inorganic, but all exists price height, the easy shortcoming of aging, suction and water-repellancy difference.

Summary of the invention:

Technical problem to be solved by this invention provides and a kind ofly can substantially improve former concrete waterproof effect, has good suction and water resistance, and is durable in use, low-cost waterproof additive.

The present invention is made by following raw materials in weight portion:

White lime 1000 stearic acid 18-22 ferrous sulfate 2-4 aluminium hydroxide 1-15

Copper sulfate 5-8 alum 5-6 high strength gypsum 4-6 animal oil 28-32

A kind of in the preferred lard of above-mentioned animal oil, butter, the sheep oil.

Preparation method of the present invention is successively according to following step:

1. preparing quick lime is pulverized or bulk adds powdering after the suitable quantity of water, sieves with 12 orders earlier, sieve with 20 orders again, and impurity elimination, standby;

2. the lime with above-mentioned weight part places in the clean container, slowly adds the clean water of 20% lime weight, stirs, slowly heating;

3. stearic acid, ferrous sulfate, aluminium hydroxide, copper sulfate, alum, the high strength gypsum with above-mentioned weight part drops in another clean container, the animal oil that adds above-mentioned weight part while stirring, stir, put into the clean water of 10% lime weight, heated and stirred is to boiling, add the clean boiling water of other 10% lime weight again, it is molten entirely to be stirred to above-mentioned chemicals;

4. the aqueous solution in 3 is added fast in 2 the whitewash, stirs, be rapidly heated, be incubated 20-40 minute to 170-250 ℃, be evaporated to dried, must white meal;

5. above-mentioned white meal is sieved with the 120-150 order, impurity elimination gets the present invention.

The present invention prevents the concrete structure member infiltration, has good suction and water resistance, and is durable in use, low price, and with the major ingredient good mixing property, last member is firm and durable, and acid-alkali-corrosive-resisting.

The using method of additive of the present invention:

1. general concrete usage quantity is the 2.5-50% of cement;

2. cement mortars such as railing, Hu Bi, roof, ground are wiped one's face, and the engineering usage quantity is 5-7%;

3. concrete such as bridge, water tower, well, retention basin and reinforced concrete works usage quantity are 5-7%;

Embodiment:

Embodiment 1

Getting 20 order white lime 100kg drops in the clean container, slowly add about 20kg clean water, continue to stir, slowly heating, get stearic acid 2kg, ferrous sulfate 0.3kg, aluminium hydroxide 1kg, copper sulfate 0.5kg, alum 0.5kg, high strength gypsum 0.5kg drops in the clean container, add lard 3kg while stirring, stir, put into the 10kg clean water, heated and stirred is to boiling, add the clean boiling water of other 10kg again, it is molten entirely to be stirred to above-mentioned chemicals, adds fast in the above-mentioned whitewash, stir, be rapidly heated to 200 ℃, be incubated 28 minutes, be evaporated to dried, get white meal, sieve with the 120-150 order, impurity elimination gets the present invention.
