Cross-linked self-adhesive glue type polymer waterproof roll and preparation method thereof

Abstract

The invention discloses a cross-linked self-adhesive glue type polymer waterproof roll which comprises a polymer film and a self-adhesive glue film coating the polymer film, wherein the self-adhesiveglue film is prepared from the following components in parts by mass: 60-70 parts of acrylate pressure-sensitive adhesive, 10-20 parts of carboxylated styrene butadiene rubber, 2-4 parts of naphthenicacid, 5-7 parts of aromatic hydrocarbon resin, 2-3 parts of sulfonate, 2-5 parts of polycarboxylic acid, 1-2 parts of catalytic promoter and 0.5-1 part of antioxidant. A preparation method comprisesthe following steps: putting the acrylate pressure-sensitive adhesive, the naphthenic acid and the aromatic hydrocarbon resin in a reaction tank, and heating to 180 DEG C; adding the carboxylated styrene butadiene rubber, and stirring for 2h; heating to 190 DEG C; adding the sulfonate and the polycarboxylic acid, and stirring for 0.5h; cooling to 150 DEG C; adding the catalytic promoter and the antioxidant, and stirring for 1h; applying an obtained product at 120-130 DEG C to a bimodal high density polyethylene film with a thickness of 1.0-2.0mm and compacting while covering with a silicone oil isolation film, and cooling to obtain the cross-linked self-adhesive glue type polymer waterproof roll. The waterproof roll disclosed by the invention quickly reacts with cement slurry within shorttime in a low-temperature environment and is firmly bonded as a whole to form a waterproof material with the same life as concrete.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, in particular to a cross-linked self-adhesive polymer waterproof coiled material and a preparation method thereof. Background technique [0002] Self-adhesive film polymer waterproof membrane is a non-toxic, non-polluting, green and environmentally friendly product, widely used in high-speed railway bridges and tunnels with cement-based interfaces, as well as industrial and civil roofs, basements, reservoirs, pools, sewage Waterproof, moisture-proof and seepage-proof projects such as civil air defense engineering floors, bathrooms, channels, etc. of the treatment system. The membrane is made of resin polymer (EVA, HDPE, PVC, TPO, etc.) sheets as the main waterproof material, and the polymer waterproof membrane is coated with self-adhesive adhesive on the polymer waterproof substrate. After the self-adhesive layer of the coil material is reacted and consolidated with the concre...

AI Technical Summary

Problems solved by technology

After the self-adhesive layer of the coil material is reacted and consolidated with the concrete slurry, a gapless combination of the waterproof layer and the concrete structure is formed, which eliminates the hidden danger of water channeling between layers, and can effectively improve the reliability of the waterproof system. It has the advantages of simple and efficient construction and does not affect the construction period. , clean, environmentally friendly, non-polluting, low comprehensive cost, and strong economy. However, at present, this type of waterproof membrane in China still has technical defects such as poor aging resistance, poor impermeability, and short service life, especially in low temperature environments. Under the circumstances, the bonding reaction time between the waterproof membrane and the cement slurry or concrete is long, and the bonding is not strong enough, which is prone to water channeling, water leakage, water seepage, etc.
