Abstract

The invention provides a creep type viscoelastic rubber waterproof coating and a production method thereof, and belongs to the technical field of waterproof materials. The creep type viscoelastic rubber waterproof coating is prepared by the follow raw materials in percentage by weight: 30-40% of 90#pitch, 15-20% of thermoplastic styrene-butadiene rubber, 10-16% of butyl rubber, 8-12% of activatedviscosified resin, 7-12% of softened oil, 3-5% of a coupling reagent, and 8-10% of filler; and the activated viscosified resin is formed through mixture of viscosified resin JT-260, alkylphenol acetylene viscosified resin, and C5 petroleum resin in the quality ratio of 1 to 2 to 3-5. According to the waterproof material, adhesive property is excellent, adhesion immediately occurs when the waterproof material is touched, stripping is difficult, the adhesion can occur on the wet substrate, and the adhesion can occur with wood, metal and other base materials; and construction is convenient and efficient, knife coating and spraying can be conducted according to requirements, film formation is quick without the need of maintenance, overlap joint is not needed, and efficiency is high.

Description

【Technical Field】 [0001] The invention relates to the technical field of waterproof products, in particular to a creep type viscoelastic rubber waterproof coating and a production method thereof. 【Background technique】 [0002] Creep type viscoelastic rubber waterproofing coating, namely Non-curable rubbermodified asphalt coating for waterproofing, is a kind of high creep property made of reactive rubber, asphalt and special additives as main raw materials The hot-melt type waterproof coating. This product maintains the creep properties of the viscous gel state, has the advantages of strong stretching ability, resistance to repeated fatigue, and can be compounded with many coiled materials. It is a multifunctional waterproof coating. This kind of waterproof coating maintains a viscous paste-like body within the service life, has application advantages such as self-healing, anti-seepage, anti-channeling, anti-fatigue, anti-aging, etc., can seal base cracks and capillary pores, an...
