Abstract

The invention provides an oil-free non-curing rubber asphalt waterproof coating capable of low-temperature construction and a manufacturing method thereof, belonging to the technical field of asphalt waterproof coatings. The oil-free non-curing rubber asphalt waterproof coating includes the following raw materials in weight percentage: 25-32% of petroleum asphalt, 6-10% of rubber modifier, 3-5% of high-temperature modifier, 30-35% of Plasticizer, 20-30% filler; Wherein, described plasticizer is environment-friendly plasticizer, and described environment-friendly plasticizer is liquid rosin resin, and described liquid rosin resin is made of soft sheet with low glass transition temperature It is a non-drying viscous liquid flow obtained by bulk modification of rosin resin, and its pour point is -5℃~-10℃. No oily components are added in the preparation process, and liquid rosin resin is added as a plasticizer to solve the problems of high-temperature construction, poor aging resistance and oil leakage of existing products.

Description

technical field [0001] The invention relates to the technical field of asphalt waterproof coatings, in particular to an oil-free non-curing rubber asphalt waterproof coating capable of low-temperature construction and a manufacturing method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a waterproof coating that maintains a viscous paste within the service life and is made of rubber, asphalt, and softening oil as the main components, and is mixed with a temperature control agent and a filler; its creep and self-healing properties Strong, has the advantages of excellent adhesive performance, sticky to the touch, difficult to peel off, long-term non-curing, etc., and can be compounded with many coils. Moreover, the construction is convenient and quick, no maintenance is required, and no overlapping is required, so it has been widely used in recent years. This kind of paint can always maintain a viscous colloidal state without forming a ...
