Waterproof and thermal insulation coating used for building exterior wall and applied to acidized environment and production method of waterproof and thermal insulation coating

Abstract

The invention discloses a waterproof and thermal insulation coating used for a building exterior wall and applied to an acidized environment and a production method of the waterproof and thermal insulation coating. The waterproof and thermal insulation coating is composed of a liquid crystal polymer, an anti-acidification component and additives; the anti-acidification component is an alkalized fiber prepared from saw dust; the additives include a dispersant, a physical foaming agent and a toughening agent; the dispersant is hydroxypropyl methyl cellulose; the physical foaming agent is a fluorocarbon compound; the toughening agent is liquid ethylene propylene rubber; and the waterproof and thermal insulation coating respectively comprises the components in percentage by weight: 79.5%-82.5%of the liquid crystal polymer, 10%-12% of the anti-acidification component, 1.3%-2.5% of the hydroxypropyl methyl cellulose, 3.5%-5.2% of the fluorocarbon compound and 1.8%-3.7% of the liquid ethylene propylene rubber. The production method disclosed by the invention is detailed and easy to realize, good in antibacterial effect, lasting in effect, environment-friendly, pollution-free, free of pungent smell and water-resistant and has a self-cleaning function.

Description

technical field [0001] The invention relates to the field of environmental protection coatings, in particular to a waterproof and heat-insulating coating for building exterior walls and a manufacturing method thereof, which are applied in acidified environments. Background technique [0002] Nowadays, the output is relatively large in the market, and the representative anti-acid corrosion coating is epoxy resin anti-corrosion coating, which has excellent adhesion, thermal stability and excellent chemical resistance, but the coating film is prone to yellowing , easy to pulverize, poor weather resistance, easy to aging. Among the existing patented technologies, there are specific deficiencies in epoxy anti-corrosion coatings. IPN technology is used to produce acid and alkali-resistant anti-corrosion coatings with new phenolic and fluoro resins on the market as film-forming substances and silicon carbide and black stone powder as fillers. Acid and alkali resistant anti-corrosi...

Problems solved by technology

However, the production cost of this material is high, the process threshold is also high, and the quality control is difficult. At the same time, the production will also cause relatively large pollution. In addition, this material has low heat resistance and high brittleness, and it is easy to pulverize during use.

[0003] The waterproof and heat-insulating coatings in the prior art are limited by the lack of technical fields and practical experience, and the waterproof and heat-insulating coatings in the full sense have not really appeared. Therefore, there is still no one with good formability, water resistance, toughness, Good heat insulation, high temperature resistance, acid corrosion resistance, environment-friendly waterproof and heat insulation coating
