Waterproof coating with good flexible permeability and preparation method thereof

Abstract

The invention discloses a waterproof coating with good flexible permeability. The waterproof coating is characterized by being prepared from the following raw materials in parts by weight: 20-45 parts of organic silicon rubber emulsions, 3-8 parts of organic silicon waterproof agents, 2-7 parts of graphene prefabricating dispersoid, 0.1-0.6 part of emulsion type deforming agents, 0.1-0.3 part of sodium carboxymethyl cellulose, 4-6 parts of C9 resin emulsion, 5-7 parts of glass microballoons, 2-4 parts of barium metaborate, 5-8 parts of precipitated barium sulfate, 1-2 parts of zinc stearate, 2-3 parts of sodium borate and 5-8 parts of silicon micropowder. The waterproof coating disclosed by the invention has the advantages of unique water resistance, high elasticity and integrity, good elongation percentage, low possibility in breakage generation, continuity in film coating without any joint, leakage resistance, and good adhesivity on various building base materials. The preparation method disclosed by the invention is simple, easy to operate and relatively low in production cost, and the adopted raw materials are easy to obtain; in addition, a produced coating has a good waterproof effect.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a waterproof coating with good flexibility and permeability and a preparation method thereof. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added with liquid medicine and other additives. Waterproof membrane has complex construction technology, high requirements for personnel knowledge, inconvenient construction and high safety hazards. Leakage often occurs in parts that are not easy to construct, and it is difficult to repair. When cement-based waterproof construction is used as a mortar protective layer The phenomenon of mortar hollowing is easy to appear, which affects the construction quality. Therefore, most waterproof projects in my country use tradit...

Problems solved by technology

Waterproof membranes have complex construction techniques, high requirements for personnel knowledge, inconvenient construction and high safety hazards. Leakage often occurs in parts that are not easy to construct, and it is difficult to repair. When cement-based waterproof construction is used as a mortar protective layer The phenomenon of mortar hollowing is easy to appear, which affects the construction quality

Therefore, most waterproof projects in my country use traditional waterproof materials. Traditional waterproof materials have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. They are prone to leakage, and the quality is difficult to guarantee. People spend a lot of money and money. Labor for repairs, disrupting people's normal life, work and production order
