Self-adhesive styrene-butadiene-styrene block copolymer (SBS) geotextile composite drainage board production formula

Abstract

The invention relates to the technical field of engineering materials, in particular to a self-adhesive styrene-butadiene-styrene block copolymer (SBS) geotextile composite drainage board production formula. The formula comprises the following raw materials: 30-50 parts by weight of high-density polyethylene, 4-8 parts by weight of a toughening agent, 0.2-0.8 part by weight of an antioxidant, 0.1-0.4 part by weight of a metal passivator, 4-8 parts by weight of calcium carbonate, 3-6 parts by weight of kaolin, 0.5-2 parts by weight of a coupling agent, 4-8 parts by weight of mica, 0.2-0.5 partby weight of a UV absorbent, and 0.2-0.6 part by weight of a cold-resistant agent. The invention overcomes the deficiencies of the prior art, and a drainage board is made of the high-density polyethylene, toughening agent, antioxidant, metal passivator, calcium carbonate, kaolin, coupling agent, mica, ultraviolet absorbent and cold-resistant agent. The waterproof board has the advantages of high cold-proof and frost-proof ability, high mechanical strength, good corrosion resistance and oxidation resistance, etc., and prolongs the service life of the drainage board, and has good social benefits.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to the production formula of a self-adhesive SBS geotextile composite drainage board. Background technique [0002] The drainage board is a construction board used to lay between the base and the construction layer in greening engineering, construction engineering, water engineering and other operations to play the function of water seepage and drainage. The drainage board is mainly composed of a base plate and a number of conical bosses on the base plate. The gap between the bosses forms a drainage channel, and the excess water seeped from the construction surface is discharged into a specific pipe through the drainage channel. To ensure that there will be no waterlogging potential at the grassroots level, the existing drainage boards have poor cold and frost resistance, low mechanical strength, poor corrosion resistance, and short service life.
