Problems solved by technology

However, it is extremely inconvenient to use and has poor performance. At the same time, it consumes a lot of resources and increases the cost of protection. The reasons are: rigid waterproof and anti-corrosion materials have good durability, but are easy to crack and deform; the porous structure cannot be filled with only 5-10% of rigid materials. There are still quite a few capillary channels leaking; the durability of the coiled material and coating of the outer protective material is only 3 to 5 years, and the inorganic material with a porous structure cannot produce a compound (chemical) reaction to form an overall waterproof structure, which is only a kind of adhesive The connection method is temporarily integrated to achieve short-term waterproof performance
With the gradual progress of oxidation, cold and heat, freeze-thaw, leakage and corrosion factors, its waterproof and anti-corrosion performance will soon lose its effect

Abstract

The invention discloses an environment-friendly type anti-cracking corrosion-resistant waterproof material and a preparation method thereof, solving the problems that the existing waterproof corrosion-resistant material is single in function, bad performance, high cost and short service life. The waterproof material disclosed by the invention consists of the following components in parts by weight: 5-15 parts of synthesized polyester resin, 3-6 parts of a penetrating agent, 1-3 parts of cellulosic fibers, 0.1-0.3 part of cellulose ether and 75-85 parts of a solvent. The invention further provides a preparation method of the waterproof material. A formula adopted by the invention can effectively achieve effect of internally and externally protecting. The environment-friendly type anti-cracking corrosion-resistant waterproof material disclosed by the invention is mainly used for infiltration type waterproof corrosion-resistant internal and external anti-corrosion engineering, which is infiltration-resistant, waterproof, moisture-proof, mildew-proof, corrosion-resistant, acid and alkali resistant, oil penetration resistant, corrosion-resistant, freezing-thawing resistant, cracking resistant, weather resistant, ageing resistant, and pollution-resistant.

Description

technical field [0001] The invention relates to an anti-crack, anti-corrosion and waterproof material, in particular to an environment-friendly anti-crack, anti-corrosion and waterproof material and a preparation method thereof. Background technique [0002] In the process of modern construction, anti-crack waterproof and anti-corrosion materials are widely used. In all construction projects, crack-resistant, waterproof and anti-corrosion materials are required to improve the durability and service life of construction projects. my country is the world's largest cement production and sales country, accounting for 30-40% of the total production and sales. The huge infrastructure projects provide a huge market for crack-resistant, waterproof and anti-corrosion materials. Traditional anti-crack waterproof and anti-corrosion materials: rigid anti-crack waterproof and anti-corrosion materials add inorganic waterproof agents, preservatives, anti-crack fibers, anti-crack expansion...
