Embodiment Construction

[0017] 10-15 parts by weight of waste rubber powder and 20-25 parts by weight of oil are mixed and heated to 200-230 ° C, and then the waste rubber powder is crushed into fine powder by mechanical shearing stress, and then 29.6-40 parts by weight of emulsified asphalt are added and Add 8-13 parts by weight of filler, 1-2 parts by weight of surfactant, 0.1-0.4 parts by weight of anti-aging agent while maintaining the temperature of 90-100 °C, and add 3-6 parts by weight of SBR and 5-9 parts by weight Parts of NR to adjust its viscosity, the steps are as follows.

[0018] The first step: Rubber can be micronized by mechanical cutting stress. Mix 4-5mm waste rubber powder without foreign matter with oil and heat it to 200-230°C. After reducing the elasticity of waste rubber powder, use a pulverizer (MILL) to press Pulverize the rubber powder with specifications within 0.01-0.1 mm, and then make the viscosity of the waste rubber mixture pulverized by heat and machinery reach 10,00...

Abstract

The present invention relates to a one-pack type unhardening adhesive film waterproofing material using waste rubber and to a method for manufacturing same, by mixing waste rubber chips with oil, heating, and grinding same into fine powder using mechanical breaking stress, and more particularly, to an one-pack type unhardening adhesive film waterproofing material using waste rubber and to a method using waste rubber that is extracted by adding heat to waste rubber to suppress the elasticity of the material, grinding the waste rubber chips into fine powder using mechanical breaking stress, and mixing with emulsified asphalt, SBR, and NR to extract the waste rubber. The present invention comprises the following steps: mixing 10 to 15 parts by weight of the waste rubber chips and 20 to 25 parts by weight of oil and heating same to 200 to 230 DEG C, and then using mechanical breaking stress to render the waste rubber chips into fine powder; mixing with 29.6 to 40 parts by weight of emulsified asphalt; mixing with 8 to 13 parts by weight of filler material, 1 to 2 parts by weight of a surfactant, and 0.1 to 0.4 parts by weight of anti-aging material while maintaining the temperature at 90 to 100 DEG C; and mixing 3 to 6 parts by weight of SBR for adjusting viscosity.

Description

technical field [0001] The invention relates to a non-hardening one-component adhesive coating film waterproof material made of waste rubber, which is made by mixing waste rubber with oil, heating, crushing into fine powder by mechanical cutting stress, and a manufacturing method thereof. Specifically, it relates to A kind of heating waste rubber, suppressing its material elasticity, using mechanical cutting stress, crushing waste rubber into fine powder, and then adding emulsified asphalt, SBR butadiene rubber (Styrene Butadiene Rubber: butadiene rubber), NR (Natural Rubber: natural rubber) The invention relates to a non-hardening one-component adhesive coating film waterproof material made of waste rubber mixed together and extracted, and a manufacturing method thereof. Background technique [0002] Generally, tires are installed on automobiles for use. After a certain period of use, they need to be replaced due to issues such as use safety. The replaced waste tires can b...
