Description

technical field [0001] The invention relates to a building material, in particular to a waterproof liquid rubber. Background technique [0002] Most of the existing waterproof materials are not environmentally friendly, and emit various gases that are poisonous and harmful to the human body. And those environmentally friendly waterproof materials have unsatisfactory places in performance and use, such as expensive, troublesome use and so on. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide an environment-friendly and easy-to-use waterproof liquid rubber. [0004] The present invention is realized through the following technical solutions. [0005] The weight formula of the waterproof liquid rubber of the present invention is different according to the different parts of use. details as follows: [0006] 1. When used in building surface waterproofing projects: EPDM rubber 15-20, styrene-butad...
