Problems solved by technology

However, there are obviously some defects in practical application: 1) It is a volatile curing material, the curing speed is slow, the construction period is long, and it cannot even be dried in places with poor ventilation; 2) It can only be applied by thin coating multiple times. Construction, if it is thick, it will lead to cracking, or it will not dry, so it w

Example Embodiment

[0026] The present invention will be further described below in conjunction with embodiments.

[0027] Produce 200 kg of the product of the present invention, in which the organic components are: polyurethane emulsion 93 kg, phthalic acid plasticizer 5 kg, silicone defoamer 2 kg; inorganic component: white cement 70 kg, light 30 kg of calcium carbonate, prepared according to their respective weight ratios, and then put the organic components, inorganic components and water in the mixing tank at a weight ratio of 1:1:0.4, and then mix them evenly. Put into use.

[0028] The following table is the result of comparison between the product and the volatile curing polymer cement waterproof coating Type I under the same conditions after actual use.

[0029]

[0030] Among them, the implementation industry standard of volatile curing polymer cement waterproof coating is: JC / T894-2001. It can be concluded from the above table that this reactive polymer cement waterproof coating has the ...

Abstract

This invention involves a kind of response type waterproof coaitng of polymer cement and prepares the method, this waterproof coating, include the aircrew one and there is no aircrew one, there is aircrew one from reacting type polyurethane cream, neighbor benzene two formic acid kinds of plasticizer and organic silicon is it steep pharmaceutical make up, have aircrew copy to made up of white cement and light body calcium carbonate to disapper. While using, the quality matching of one per group is: There are aircrew's shares: Response polyurethane 100 cream, neighbor benzene two formic acid kinds of 5 plasticizer, organic silicon is it steep 5 pharmaceutical to disappear; The weight matching of all raw material is when there is no aircrew one: white cement is 100. light body calcium carbonate is 40. The response type waterproof coating of polymer has already had the intersity of building inorganic material of cement high, able to bear it good advantage, have good high elasticity of high polymer material and waterproof performance.

Description

technical field [0001] The invention relates to a reactive polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Polymer cement waterproof coating is a kind of water-based environmental protection waterproof coating that has emerged in recent years. The products currently on the market are mainly composed of acrylic resin and inorganic ingredients. This type of product has high strength, no seams, and strong adhesion. , high temperature resistance, cold construction, non-toxic and harmless and so on. However, there are obviously some defects in practical application: 1) It is a volatile curing material, the curing speed is slow, the construction period is long, and it cannot even be dried in places with poor ventilation; 2) It can only be applied by thin coating multiple times. Construction, if it is thick, it will lead to cracking, or it will not dry, so it will take a lot of time and affect the quality; 3) Poor water resistance,...
