Problems solved by technology

[0003] However, there are many types of synthesis techniques for synthetic resin waterproof sheets, and the performance of waterproof sheets produced by various methods is also uneven, good and bad.
In order to reduce costs, many companies often sacrifice product quality at the expense of product quality. Currently, waterproof sheets sold on the market often fail to meet the requirements for performance indicators such as waterproofing and aging resistance. How to produce real low-cost, waterproof performance and Waterproof sheets with good aging resistance have become an urgent problem to be solved

Abstract

The invention discloses a preparation process of a waterproof enhancement sheet in modified polyvinylchloride, comprising the following steps of material preparing, hot mixing, cold mixing, extrusion granulation, and extrusion sheet-forming. The invention has the advantages of simple preparation process, low production cost, low processing difficulty and effective reduction of the production costof enterprises; meanwhile, compared with a waterproof sheet produced by the same type of the production process, the waterproof sheet produced by the process of the invention has better waterproof performance and ageing resistance. The invention effectively improves the tension of the sheet, performance indexes of elongation percentage and low temperature flexibility, and the waterproof performance of the sheet.

Description

technical field [0001] The invention relates to a preparation process of a waterproof building material, in particular to a preparation process of a modified polyvinyl chloride internally reinforced waterproof sheet. Background technique [0002] As we all know, waterproof building materials are one of the indispensable building materials in the construction industry at present. Waterproof building materials are mainly divided into two categories: polymer synthetic resin waterproof sheets and synthetic resin waterproof sheets, and synthetic resin waterproof sheets are divided into EVA Waterproof sheet, PE waterproof sheet, PVC waterproof sheet and ECB waterproof sheet, among which PVC waterproof sheet is mainly a waterproof roll made of polyvinyl chloride (PVC) material, which has low cost, aging resistance and UV resistance Good, with a certain tensile strength and elongation at break, large shrinkage, good low temperature flexibility, convenient construction, etc., especia...
