Abstract
The invention discloses a cement-base waterproof coating. The cement-base waterproof coating comprises the following components in parts by weight: 40-60 parts of portland cement, 20-30 parts of quartz sand, 40-60 parts of polymer emulsion, 10-20 parts of mineral additive, 0.5-1.0 part of dispersing agent, 5-10 parts of water reducer, and 20-30 parts of water. The invention also discloses a preparation method for the cement-base waterproof coating. Due to the addition of the polymer emulsion in the cement base material, the compressive strength of the coating can be effectively improved, and the durability of the coating is also enhanced; due to the addition of the dispersing agent, the polymer emulsion is effectively guaranteed to be dispersed in the portland cement, and the effect of the polymer emulsion is enhanced; and the water reducer is used for enhancing the viscosity and elasticity of the coating, and can effectively reduce the amount of water for blending.
Description
Technical field
The present invention relates to a kind of cement-base waterproof coating and preparation method thereof, belong to the functional material science and technology field.
Background technology
Waterproof paint is a kind of fluidised form or half fluidised form material, the techniques such as available brush, spray are coated on matrix surface, chemical reaction through between solvent evaporates or each component, formation has the continuous film of certain elasticity and thickness, make substrate surface and water isolated, and can resist certain water pressure, thereby play waterproof and moisture-proof role.
Traditional waterproof paint is Shortcomings still at aspects such as water resistance, water tolerance, intensity, resistance to compressions.
Summary of the invention
In order to address the above problem, the object of the invention is to improve a kind of good water-proof effect, water tolerance is strong, intensity is high cement-base waterproof coating and preparation method thereof.
For realizing above-mentioned technical purpose, technical scheme provided by the present invention is:
A kind of cement-base waterproof coating, is characterized in that, comprise take component and each component ratio of weight and number as:
Silicate cement: 40-60 part;
Quartz sand: 20-30 part;
Polymer emulsion: 40-60 part;
Mineral admixture: 10-20 part;
Dispersion agent: 0.5-1.0 part;
Water reducer: 5-10 part;
Water: 20-30 part.
Described polymer emulsion is any in aminopropan acid esters, polyacrylic ester, styrene-butadiene rubber(SBR), silicon rubber and polyvinyl chloride.
Described mineral admixture is at least one in silicon ash, flyash.
Described dispersion agent is any in sodium polyacrylate, wooden sodium carbonate, petroleum sodium sulfonate, polyacrylic acid amide, hydrolysis ammonium acrylate, phosphoric acid ester.
And described water reducer is trimeric cyanamide polyester or polyacrylic ester, and the water-reducing rate of described water reducer >=20%.
A kind of preparation method of cement-base waterproof coating, is characterized in that, comprises the following steps:
(1) at first quartz sand, polymer emulsion are mixed to the rear 15-30min of stirring;
(2) then silicate cement, mineral admixture are added in the described compound of step (1) and continue to be stirred to evenly;
(3) water reducer, dispersion agent and water are added in the described compound of step (2) and stir 30-45min blanking moulding.
Beneficial effect of the present invention is: the present invention, by add polymer emulsion in cement matrix, can effectively strengthen the ultimate compression strength of coating, has increased weather resistance simultaneously.And dispersion agent adds, effectively guaranteed the dispersiveness of polymer emulsion in silicate cement, strengthened its action effect, described water reducer is viscous force and the elastic force for strengthening coating, can effectively reduce the mixing water amount.
