CN1634792A - Waterproof additives for building materials and method for making same - Google Patents

Abstract

Disclosed is a water-proof additive for construction materials, comprising burned lime, geoceric acid, ferrous sulfate, aluminium hydroxide, copper sulphate, alum, high-strength gypsum and animal oil. It is made by dissolving in water, heating for complete dissolving, then evaporating to be dried. The additive provided by the invention can prevent concrete architecture structural elements from water seepage, blend with main material perfectly, and the final elements are robust and resist corrosion.

Description

Material of construction waterproof additive and preparation method thereof

Technical field:

The present invention relates to a kind of material of construction with concrete waterproof additive particularly.

Background technology:

At present, leakage of building is increasingly extensive, and the trend that grows in intensity is arranged, and causes the reason of this phenomenon to have material of construction, management, design, construction etc. all multifactor, but with in the main material concrete there is not the fine waterproof additive relevant yet, existing concrete additive is of a great variety, is divided into organically, and is inorganic, but all exist one or more shortcomings, for example the price height easily wears out, and suction and water-repellancy are poor.

Summary of the invention:

The objective of the invention is to overcome the deficiency of prior art, provide a kind of and can substantially improve former concrete waterproof effect, have good suction and water resistance, durable in use, low-cost waterproof additive.

Material of construction waterproof additive of the present invention is made up of white lime, stearic acid, ferrous sulfate, aluminium hydroxide, copper sulfate, alum, high strength gypsum, animal oil, with water-soluble, is evaporated to driedly, and sieving forms, and it is characterized in that: the proportioning of described component is as follows:

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

The present invention prepares the method for above-mentioned additive and carries out according to following process successively:

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

2) lime with the afore mentioned rules amount places 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 the afore mentioned rules amount drops in another clean container, stir on the limit, the limit adds the animal oil of specified amount, stir, put into the clean water of 10% lime weight, heating, be stirred to and boil, the clean boiling water that adds other 10% lime weight again stirs, and is molten entirely to above-mentioned chemicals;

4) with 3) in the aqueous solution fast to going into 2) whitewash in, stir, be rapidly heated to 170-250 ℃, be incubated 20-40 minute, be evaporated to dried, must white meal;

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

Additive salient features of the present invention is to prevent the infiltration of concrete building structures member, and with the major ingredient good mixing property, last member is sturdy and durable, and acid-alkali-corrosive-resisting.

Embodiment 1 gets 20 order white lime double centners and drops in the clean container, slowly adds about 20 kilograms of clean waters, continues to stir, slowly heating; Get in 2 kilograms of stearic acid, 1 kilogram in aluminium hydroxide, 0.5 kilogram in copper sulfate, 0.5 kilogram in alum, 0.5 kilogram of input of high strength gypsum, one clean container, stir evenly, drop into 3 kilograms of lards while stirring, stir, put into 10 kilograms of clean waters, heated and stirred is to boiling, add 10 kilograms of other clean boiling water again, stir, molten entirely to above-mentioned chemicals, fast to going 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 mesh sieve, impurity elimination gets white meal.
