Abstract

The invention provides a production formula of a waterproof roll sizing material. The waterproof roll sizing material comprises the following components: 50-60 parts of asphalt; 0-6 parts of an oil product; 2 to 8 parts of SBS (styrene butadiene styrene); 0 to 6 parts of SBR; 0 to 5 parts of butyl rubber; 2 to 10 parts of tackifying resin; and 20-32 parts of a filler. According to the rubber material applied to the S-CLF waterproof coiled material, the use amount of an oil product in a formula is reduced, and the selection and the use amount ratio of the oil product, the rubber modifier, the butyl rubber and the tackifying resin are specifically changed. Under the condition that the cost is basically consistent, the rubber material which is low in oil content and small in needle penetration and has almost unchanged mechanical properties compared with a high-oil-content asphalt rubber material is obtained. The problems that the appearance of the S-CLF waterproof coiled material changes color with yellowish-brown color sand, and local color sand of the coiled material sinks are solved. The invention also provides the S-CLF waterproof coiled material, the S-CLF waterproof coiled material comprises an A-side sizing material, a cross laminated film and a B-side sizing material which are bonded in sequence, and the A-side sizing material is the sizing material applied to the S-CLF waterproof coiled material.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and in particular relates to a production formula and a preparation process of waterproof coiled material glue. Background technique [0002] S-CLF waterproof membrane is composed of imported super-strength cross-laminated membrane, self-adhesive rubber asphalt compound with high-performance formula, and isolation membrane. It is a tireless membrane with excellent tensile, elongation and tear resistance. Self-adhesive waterproofing membrane with excellent UV resistance and stability. Including single-sided self-adhesive (NS type), double-sided self-adhesive (ND type) and pre-paved anti-adhesive (YC type). As people's requirements for quality of life are getting higher and higher, people pay more and more attention to waterproofing. Nowadays, more and more basement floor waterproofing adopts the pre-paved anti-adhesive process to achieve a good waterproof effect of "external ...
