AI Technical Summary

Problems solved by technology

The non-vulcanized waterproof rubber made by this process has a certain viscosity, but when it is bonded to the base surface, the base surface must be treated with an interface treatment agent before it can be bonded; for a wet base surface, with water The penetration of the adhesive layer will cause the disadvantage of detachment, resulting in damage to the waterproof function; and as time goes by, the softener-oil or Coumarone will continue to precipitate, resulting in aging and cracking of the non-vulcanized waterproof rubber , thus losing the waterproof performance, the service life is short, and the continuity of the waterproof function of the building is destroyed

Abstract

A pressure-sensitive self-healing waterproof rubber material and a manufacturing method thereof. It relates to a waterproof rubber material and a manufacturing method thereof, which has super-strong adhesive performance and self-healing function, and can be applied to wet base surfaces and low-temperature construction without using adhesives or interface treatment agents, directly on the base surface Surface use, long-term use still has excellent waterproof performance. The production method is as follows: banburying the rubber and heat-smelting; adding softener, surfactant and compounding agent to the banburying, and then heat-smelting to obtain a pressure-sensitive self-healing waterproof rubber material. Among them, the softener is a mixture of polyisobutylene, engine oil, coumarone, etc.; the surfactant is a hydrophilic agent; the compounding agent is an accelerator, a filler, and a reinforcing agent. The product of the invention has excellent performance, and is suitable for roofing engineering of industrial and civil buildings, underground engineering, subway engineering, municipal engineering, and waterproof layers of pools and canals.

Description

Technical field: [0001] The invention relates to a waterproof rubber material and a manufacturing method thereof. In particular, a pressure-sensitive self-healing waterproof rubber material and a manufacturing method thereof. Background technique: [0002] Waterproof rubber materials have been widely used as one of the waterproof components of buildings. The coiled material made of the waterproof rubber material can be placed in the foundation or top waterproof layer of the building, which can play a good waterproof effect. As a waterproof rubber material, when it is used in the waterproof structure of buildings, it must first have a certain tensile strength and softness, and can be bonded to the base surface as a whole, with the function of blocking water infiltration; due to the The use time is long, so it is required to be able to use for a long time without cracking and maintain a good and continuous waterproof function in an all-weather environment. According to diff...
