Multifunctional concentrated material used for preparing kitchen and bath cement-based waterproof material

Abstract

The invention relates to a multifunctional concentrated material used for preparing a kitchen and bath cement-based waterproof material. The multifunctional concentrated material is composed of waste rubber powder, a silane coupling agent, alcohol blend, high-alumina cement, redispersible latex powder, cellulose ether, a delayed coagulant, a coagulation accelerator, a water reducer, an anti-freezing agent (added in winter), and a water repellent, and is a one-component material. The cement-based waterproof material is prepared by mixing the multifunctional concentrated material with cement and quartz powder; is used for kitchen and bath waterproof construction; possesses both excellent characteristics of waterproofing coatings and waterproof mortars, and excellent waterproof performance, so that waterproof effect can be achieved just by a thin coating layer in construction; and also possesses excellent rigidity which is convenient for paving of tiling in following procedures, and is suitable for waterproofing of waterward sides and water lee sides. Addition of waste rubber powder is capable of reducing density of the polymer cement waterproof material, increasing spreading rate of waterproof coatings, changing waste into valuables, and realizing recycling of resources.

Description

technical field [0001] The invention relates to a concentrated material for waterproof materials, in particular to a multifunctional concentrated material for kitchen and bathroom cement-based waterproof materials, which belongs to the technical field of waterproof materials in the construction industry. Background technique [0002] Waterproof material is an important material in the field of building protection, mainly divided into two categories: waterproof membrane and waterproof coating. Polymer cement waterproof coating is an organic liquid material composed of polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and other polymer emulsions and various additives, and inorganic fillers such as cement, quartz sand, light and heavy calcium carbonate and various It is a two-component, water-based architectural waterproof coating made of inorganic powder composed of various additives through reasonable proportioning and compounding. Polymer cement waterproof co...

AI Technical Summary

Problems solved by technology

For example, patent CN101891432 B discloses a osmotic crystalline waterproof coating, which is composed of Portland cement, quartz sand, filler, calcium ion compound, crystallization precipitant, complexing aid, film-forming aid, complexing agent, polycarboxylic acid Composed of similar superplasticizers and methyl cellulose, this product grows insoluble crystals in the capillary pores and microcracks on the concrete surface, blocking the capillary channels and microcracks, thereby improving the impermeability of concrete, achieving waterproof, The purpose of leak plugging, although this type of waterproof coating can obtain better waterproof effect, its flexibility is relatively poor; Patent CN 1952030 B discloses a kind of two-component polyurethane waterproof coating, and described A component comprises: three kinds of polyurethane Ether (3050#, 220#, 210#), TDI, plasticizer, component B includes: softener (liquid petroleum resin), inorganic powder (cement, fly ash, talcum powder, heavy calcium powder, zinc oxide , lime powder), mixed liquid (water and non-ionic surfactant), nano-calcium, the preparation method includes the steps of preparing prepolymer, and the process is relatively cumbersome

[0005] Combining the characteristics of kitchen and bathroom waterproofing projects and the above-mentioned defects, a single-component polymer cement-based waterproofing with excellent performance of waterproof coating and waterproof mortar is produced The material can well solve the deficiencies of the existing technology, and has not been reported so far
