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 0.01-0.1mm, and then make the viscosity of the waste rubber mixture pulverized by heat and machinery reach 10,000...

Abstract

Disclosed therein is a non-curing one-component adhesive waterproof material using scrap rubber and a preparation method thereof in which scrap rubber is mixed with oil, heated and pulverized into size-reduced rubber under mechanical shear stress, and more particularly, to a non-curing one-component adhesive waterproof material using scrap rubber and a preparation method thereof in which scrap rubber is heated to have a reduced elasticity, pulverized into size-reduced rubber under mechanical shear stress, and then mixed with emulsified asphalt, styrene butadiene rubber (SBR), and natural rubber (NR). The present invention includes: 10 to 15 parts by weight of scrap rubber chips; 20 to 25 parts by weight of oil, the scrap rubber chips and the oil being mixed together, heated at 200 to 230 °C and then subjected to size reduction under mechanical shear stress to pulverize the scrap rubber chips into size-reduced rubber; and 29.6 to 40 parts by weight of emulsified asphalt being mixed with the size-reduced rubber. The mixture of the emulsified asphalt and the size-reduced rubber is mixed with 8 to 13 parts by weight of a filler, 1 to 2 parts by weight of a surfactant, and 0.1 to 0.4 part by weight of an anti-ageing agent at a temperature of 90 to 100 °C, and then further mixed with 3 to 6 parts by weight of SBR and 5 to 9 parts by weight of NR for viscosity control.

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 (StyreneButadieneRubber: butadiene rubber), NR (NaturalRubber: natural rubber) mixed together The invention discloses a non-hardening one-component adhesive coating film waterproof material made of extracted waste rubber 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 be process...
