Non-curing adhesive waterproof material using recycled rubber, and manufacturing method thereof

Abstract

The present invention relates to a non-curing, adhesive, and waterproof material using recycled rubber, and to a manufacturing method thereof, and more particularly, to a non-curing, adhesive, and waterproof material using recycled rubber, which is used to form a waterproof sheet by: adding recycled rubber to softener, tackifier, filler, SBS resin, PVA pressure sensitive adhesive, and the like; then mixing the resultant material with a mechanical forced mixer to form a material with good adhesiveness; and then depositing the material on an asphalt sheet, HDPE sheet, nonwoven fabric, PE foam, etc., according to the intended application, and to a manufacturing method for the waterproof material. According to the present invention, 18-28 wt% of recycled rubber (EPDM-based or NR-based), 6-15 wt% of softener (paraffin oil or aromatic oil), 14-24 wt% of tackifier (polybutene or PVA-based tackifier), 40-60 wt% of filler (talc, calcium bicarbonate, or cement), and 2-6 wt% of SBS-based thermoplastic resin are mechanically forcibly mixed.

Description

technical field [0001] The invention relates to a non-vulcanized waterproof adhesive material using recycled rubber and a manufacturing method thereof, specifically, a method of adding recycled rubber to softeners, tackifiers, fillers, SBS resins, PVA pressure-sensitive adhesives, etc. After the material is soaked, use a mechanical type forced mixer to make a substance with excellent viscosity, and then use recycled rubber non-vulcanized waterproof adhesive material to coat according to the usage methods such as asphalt board, HDPE board, non-woven fabric, polyethylene foam, etc. The final waterproof board and its manufacturing method. Background technique [0002] The traditional method of using recycled rubber is to process recycled waste tires, EPDM, surgical gloves, condoms, balloons and various weather strips, and then treat and separate them by physical or chemical methods to remove rags, After foreign objects such as iron sheets are treated by pressure cooker, acid t...

Problems solved by technology

[0002] The traditional method of using recycled rubber is to process recycled waste tires, EPDM, surgical gloves, condoms, balloons and various weather strips, and then treat and separate them by physical or chemical methods to remove rags, After foreign objects such as iron sheets are treated by pressure cooker, acid treatment, plasticized rubber milling, rubber freezing and then crushing, etc., the crushed rubber particles or rubber blocks are mixed with tackifiers to make mats, squares, etc., so that Made into flooring materials, or through thermal decomposition, oil and carbon in rubber are separated and captured for use, but generally only undergo one-time processing
