Problems solved by technology

However, in the process of use, there are disadvantages such as inconvenient use and poor performance, while consuming a large amount of resources and increasing protection costs. This is because rigid waterproof and anti-corrosion materials have good durability, but are easy to crack and deform; the porous structure cannot be only 5-10% The rigid material filled still has quite a few capillary channels leaking

Abstract

The invention discloses a mould-proof waterproof material. The mould-proof waterproof material is prepared from, by weight, 20-30 parts of acrylic emulsion, 10-15 parts of styrene-butadiene-styrene segmented copolymer, 8-12 parts of petroleum resin, 10-14 parts of polyvinyl alcohol, 8-13 parts of hydroxypropyl methyl cellulose, 5-9 parts of 4,6-dihydroxypyrimidine, 8-12 parts of cis-3-hexenyl isobutyrate, 4-8 parts of magnolol, 7-12 parts of 1-naphthol-3,6-sodium disulfonate, 3-6 parts of 2-amino-4-tert-butyl phenol, 1-3 parts of triethoxy ethyl silane, 2-6 parts of methyl heptenone, 1-3 parts of dibutyltin dichloride and 5-10 parts of silica sol. The mould-proof waterproof material has excellent mould-proof waterproof performances; according to tests with penicillium funiculosum, the waterproof material is capable of proofing 10-100mm water leakage under the condition that inoculum size is 104-106cfu / ml. Therefore, the mould-proof waterproof material can be widely applied to industries of construction and the like.

Description

technical field [0001] The invention belongs to the field of waterproof materials, and in particular relates to a mildew-proof and waterproof material and a preparation method thereof. Background technique [0002] In the construction industry, the building envelope needs to prevent the penetration of rainwater, snowwater and groundwater, and prevent the erosion of moisture, steam and other harmful gases in the air. These anti-penetration, leakage and erosion materials require the use of waterproof materials. The modern construction process uses crack-resistant, waterproof and anti-corrosion materials, which can improve the durability and service life of construction projects. Traditional anti-crack, waterproof and anti-corrosion materials mainly include rigid anti-crack, waterproof and anti-corrosion materials. In cement concrete and mortar, inorganic waterproofing agents, preservatives, anti-cracking fibers, anti-cracking expansion agents, water-repellent agents, water-re...
