Abstract

The invention discloses high polymer waterproof rubber powder, which is prepared from the following components: 85-95% of 60 to 80-mesh fine rubber powder obtained by grinding waste tires. Compared with the prior art, a prepared waterproof coiled material is better in elasticity and smoothness than the traditional good asphalt high polymer waterproof material.

Description

technical field [0001] The invention relates to the field of polymer waterproofing, in particular to a polymer waterproof rubber powder, a polymer waterproof material and a preparation method thereof. Background technique [0002] Asphalt waterproofing membranes are generally made of rollable sheet-like waterproofing materials by dipping molten asphalt on the surface of base paper, fiber felt and other carcass materials. During the preparation process, the existing problems are that the melting time is long and the melting temperature is high. The finished waterproof membrane has poor finish. Contents of the invention [0003] One of the purposes of the invention is to provide a polymer waterproof rubber powder. The elasticity and smoothness of the waterproof membrane prepared by the polymer waterproof rubber powder are superior to the traditional good asphalt polymer waterproof materials. [0004] The technical proposal is: a polymer waterproof rubber powder, which is ma...
