Abstract

The invention discloses a high viscosity rapid room temperature curing sealant comprising the following raw materials by weight: 30-40 parts of chloroprene rubber, 20-30 parts of styrene butadiene rubber, 40-50 parts of terpene resin, 35-45 parts of epoxy resin, 7-12 parts of an antioxidant, 160-180 parts of an organic solvent, 16-19 parts of a thickener, 110-130 parts of light calcium carbonate, 10-13 parts of ethylene glycol, 2.5-3.5 parts of a curing accelerator and 7-11 parts of a defoaming agent. The high viscosity rapid room temperature curing sealant is high in viscosity, short in curing time at room temperature, easy to use, and wide in range of uses.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to a high-viscosity fast room temperature curing sealant. Background technique [0002] Sealant is a kind of sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the gap in the configuration to play a sealing role. Usually, natural resin, synthetic resin, styrene-butadiene rubber, synthetic rubber and asphalt and other dry or non-dry viscous materials are used as base materials, combined with inert fillers such as talcum powder, titanium dioxide, clay, carbon black and asbestos, and then It is made by adding additives such as solvent, plasticizer, curing agent and accelerator. The sealants in the prior art are mostly used in the construction industry, and have the functions of bonding, sealing, waterproofing, heat insulation, etc., but they are often affected by various factor...
