Problems solved by technology

[0004] However, there is currently no technical publication on the application of magnesium aluminum silicate or magnesium lithium silicate to water-based rubber modified emulsified asphalt waterproof coatings. Magnesium aluminum silicate or magnesium lithium silicate is used as a paste agent for water-based rubber modified emulsified asphalt waterproofing The coating mainly has the following two difficulties: first, it is difficult to add. Magnesium aluminum silicate and magnesium lithium silicate are both types of pasting agents that thicken rapidly. In the system, the second is that the formula selection requirements are high. Magnesium aluminum silicate and magnesium lithium silicate in water-based rubber modified emulsified asphalt are prone to chemical reactions and charge neutralization with emulsifiers, which will damage the stability of the system, or cause the system It is easy to break the emulsion, or the paste agent fails to thicken. Therefore, it is important to solve the above technical problems through the development of new processes and formulas. Successfully applying magnesium aluminum silicate or magnesium lithium silicate to water-based rubber modified emulsified asphalt waterproof coatings practical significance

Abstract

The invention relates to multi-path thick coating and one-step molded rubber-state waterproof coating and a preparation method thereof and belongs to the technical field of sealing water prevention. The rubber-state waterproof coating provided by the invention is mainly prepared from the following raw materials in percentage by mass: 0 to 75 percent of modified asphalt, 0 to 80 percent of asphaltregeneration agent, 0.01 to 30 percent of quick-drying creaming agent and 10 to 70 percent of emulsified liquid; the rubber-state waterproof coating is prepared through steps of preparing a rubber asphalt mixture, preparing the emulsified liquid, emulsifying and creaming and de-foaming. According to the rubber-state waterproof coating, an inorganic creaming agent is used as the quick-drying creaming agent and the emulsified liquid is used for emulsifying and creaming the rubber asphalt mixture through a colloid mill by adopting a one-pot method and the prepared rubber-state waterproof coatingis uniform, fine and smooth and has high quality; the rubber-state waterproof coating has very good thixotropic performance, rapid dehydration and drying properties and excellent construction and application performance; the production efficiency is improved by applying the one-pot method and quality stability of a product and environment protection are facilitated.

Description

technical field [0001] The invention relates to the technical field of sealing and waterproofing, in particular to a multi-layer thick coating and one-time forming rubber waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coatings are mainly used for sealing and waterproofing of large areas and detailed nodes of buildings. The waterproof coating is brushed or sprayed on the base surface, and after curing, it forms a waterproof coating film with good integrity and no seams, which has good adhesion and sealing to the base surface. However, the application of waterproof coatings often requires multiple layers of thin coatings to achieve the required thickness of the waterproof layer. Due to the slow drying speed of waterproof coatings, for example, when applying emulsion-type waterproof coatings, it is necessary to wait for the previous layer of waterproof coating to dry before proceeding to the next layer of waterproof coating. Const...
