Problems solved by technology

Inorganic fillers are mainly heavy calcium carbonate, talcum powder, etc. The products are not satisfactory in terms of high and low temperature resistance, wear resistance and scratch resistance. The density of heavy calcium carbonate is 2.6-2.9g / cm 3 , high density, the density of the compounded PVC waterproof membrane raw material is 1.5 ~ 1.7g / cm 3 , the high specific gravity is not conducive to the use of building materials, and at the same time, it increases the production cost virtually
[0003] In addition, mold is a key biological species that causes microbial aging of plastic polymer materials, especially the production of polyvinyl chloride requires the addition of plasticizers and the use of waterproof membranes in damp environments, which are more likely to breed mold and accelerate the biological degradation of membranes. Aging, shortening service life

Abstract

The invention discloses a polyvinyl chloride waterproof coiled material and a production technology thereof, and belongs to the field of macromolecular structural waterproof coiled materials. The polyvinyl chloride waterproof coiled material disclosed by the invention comprises polyvinyl chloride, inorganic filler, plasticizer, impact modifier, stabilizer, lubricant, and further comprises anti-mildew agent and softener, wherein the lubricant is composed of stearic acid and paraffin, the inorganic filler is hollow glass beads, the anti-mildew agent is o-phenylphenol, and the softener is 2-heptadecyl-N-aminoethyl imidazoline propylene epoxide. The tensile property, the anti-impact property, the biological ageing resistance property, the high-temperature thermal ageing resistance property andthe heat insulation property of the obtained polyvinyl chloride waterproof coiled material are all significantly improved, and meanwhile, the hollow glass beads obtained by treating coal ash are usedas raw material, so that the cost of the coiled material is reduced, and thus the coiled material is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of polymer building waterproof coiled material, in particular to a polyvinyl chloride waterproof coiled material and a production process thereof. Background technique [0002] The existing polyvinyl chloride waterproof membrane is made of polyvinyl chloride as the main raw material, adding inorganic filler modifiers, plasticizers, stabilizers, colorants and other auxiliary materials, and is produced by extrusion and calendering processes. There are single-layer and Homogeneous compound of two kinds. Inorganic fillers are mainly heavy calcium carbonate, talcum powder, etc. The products are not satisfactory in terms of high and low temperature resistance, wear resistance and scratch resistance. The density of heavy calcium carbonate is 2.6-2.9g / cm 3 , the density is high, and the density of the raw material of PVC waterproof membrane after compounding is 1.5~1.7g / cm 3 , the high specific gravity is not conducive to t...
