Reacting polymer cement waterproof coating and preparing method thereof

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,...

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 will take a lot of time and affect the quality; 3) Poor water resistance, after use in underground engineering, water absorption will swell, strength will decrease, and affect the waterproof effect; 4) The index is low, of which JS I type, tensile strength ≥ 1.2mpa, elongation at break ≥ 200%, of which JS II type: tensile strength ≥ 1.8mpa, elongation at break ≥ 80%
