Abstract

The invention belongs to the field of waterproof masks and specifically relates to an anti-aging waterproof mask for waterproof roll materials. The invention is characterized in that the mask is manufactured by a three-layer co-extrusion technology and is divided into three layers. Each layer of the mask comprises the following raw materials, by weight, 55-98% of mixed resin, 0.5-20% of carbon black, 0.1-10% of a coupling agent, 0.5-5% of a complex antioxidant, 0.1-10% of a processing aid and 0.5-10% of a dispersant. The mask provided by the invention has advantages of low cost, good aging resistance and long service life. The mask provided by the invention can replace an aluminized mask for a common waterproof roll material to reduce parts of cost. As a special anti-aging formula is adopted, the roll materials have good aging resistance, and service life of the waterproof roll materials can be prolonged. The mask provided by the invention can be applied to SBS modified bitumen waterproof roll materials and self-adhesive waterproof roll materials.

Description

technical field [0001] The invention belongs to the field of waterproof facial masks, and in particular relates to an aging-resistant waterproof facial mask specially used for waterproof coiled materials. Background technique [0002] SBS modified bitumen waterproof membrane has good temperature difference resistance, high elasticity and fatigue resistance, high elongation, strong puncture resistance and tear resistance, and is widely used in industry and Waterproofing projects such as roofs, basements, and toilets of civil buildings, as well as waterproofing and moisture-proofing projects such as roof gardens, roads, bridges, tunnels, parking lots, and swimming pools. The surface of the SBS modified asphalt waterproofing membrane is generally covered with a waterproof film. The waterproof film is generally made of polyethylene film (PE), which has poor aging resistance and generally has a service life of only 5 years. After aging and damage, the SBS modified asphalt must be...
