Problems solved by technology

[0004] However, the currently commonly used non-curing rubber asphalt waterproof coating itself is viscous and has strong cohesive force, so it is difficult to directly scrape and wipe the construction. Therefore, most of them adopt the method of heating and melting. After the heating equipment is heated to a certain temperature, the material has good fluidity, and then it is applied by scraping or spraying
Usually, the paint needs to be heated to 120-150°C before construction. The construction is difficult, the requirements for machines and tools are also high, and the energy consumption is high. In addition, pungent and unpleasant harmful gases will be produced during the heating construction process, causing pollution and greatly affecting the The use and promotion of such products

preparation example Construction

[0030] The preparation method of above-mentioned HA101 crosslinking agent is as follows: Vegetable oil pitch 50% (by weight percentage, the same below), polyester waste 35%, glycerol 14.9%, lithium hydroxide 0.1%, add vegetable oil pitch Stir in the kettle and heat up to 180°C, add glycerin and lithium hydroxide, then heat up to 210°C, add polyester waste and heat up to 240°C, keep warm for 2 hours, then heat up to 270-280°C, keep warm for 3 hours, and cool down After reaching 200°C, add high-boiling point aromatic oil and cool to room temperature to obtain HA101 crosslinking agent.

[0031]The DB201 crosslinking agent is an acrylic polymer, and its Tg<-20°C. The acrylate polymer is formed by copolymerization of the following components by mass content: styrene 8.5%, ethyl acrylate 9.5%, butyl acrylate 10%, methyl methacrylate 10%, acrylic acid 1.5%, acrylic acid-2 - 15% of ethylhexyl ester, 1% of initiator, 2% of emulsifier, 1% of ammonia water, and the balance is water.

Abstract

A kind of non-cured rubber asphalt waterproof paint for normal temperature scraping, including high temperature crosslinking paint, HA101 crosslinking agent, DB201 crosslinking agent, heavy oil, alkyd resin, diluent, silicon micropowder, heavy calcium powder, high temperature crosslinking paint consists of It is synthesized from asphalt, rubber powder, SBS, SBR, DOP and rubber oil; HA101 crosslinking agent is a mixture of high boiling point aromatic oil and vegetable oil asphalt binder; DB201 crosslinking agent is acrylic polymer with Tg<‑ 20°C. The coordination and synergistic effect of each component in the formula of the present invention improves the low-temperature creep performance of the coating, greatly reduces the viscosity, enables the product to be environmentally friendly at room temperature without heating, has good anti-aging performance and good water resistance, and improves the construction efficiency. Convenience and adhesion to coils.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to a non-cured rubber asphalt waterproof coating for scraping at room temperature and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating, with asphalt as the main body, is modified by various elastomers and plastics to make it have a certain cohesive force. After being stressed, it can cause sliding inside the material to produce plastic deformation, greatly reducing material internal stress. The advantages of non-curing rubber asphalt waterproof coating are as follows: it will never cure, and it will always remain gluey after construction; Adapt to the deformation of the base layer; strong self-healing, even if the waterproof layer is damaged during construction, it can repair itself and maintain a complete waterproof layer; it can be used with other waterproof materials at the same time to form a composite waterpro...
