A metal mesh reinforced polyethylene composite waterproofing coiled material, which is composed of a composite fiber layer on both sides of a polyethylene film as the main waterproof layer and a metal grid in the polyethylene film as the characteristic part. It has the advantages of high strength, and can meet the requirements of special engineering construction even if low-density polyethylene is used. If polyester non-woven fabric is used as the surface composite layer, it also has heat insulation and heat preservation effects, and is suitable for roof waterproofing projects.
Description
本专利申请涉及建筑工程防水材料。This patent application relates to waterproof materials for construction engineering.
与本专利申请有关的技术是申请人的专利号96248566.7双面纤维增强聚乙烯复合防水卷材。它是在聚乙烯膜为主防水层的两面复合上纤维布做增强防滑层，它具有防水性能好、寿命长，很好的与水泥基层粘结等优点。但生产时采用线性低密聚乙烯、特别是低密度聚乙烯时，抗拉强度较低，满足不了特殊工程的防水要求。The technology related to this patent application is the applicant's patent No. 96248566.7 double-sided fiber reinforced polyethylene composite waterproof membrane. It is made of fiber cloth on both sides of the polyethylene film as the main waterproof layer as a reinforced anti-skid layer. It has the advantages of good waterproof performance, long life, and good bonding with the cement base. However, when linear low-density polyethylene is used in production, especially low-density polyethylene, the tensile strength is low and cannot meet the waterproof requirements of special projects.
本专利申请的目的，是进一步提高聚乙烯防水卷材的抗拉强度，满足特殊工程的防水要求。The purpose of this patent application is to further improve the tensile strength of the polyethylene waterproof membrane to meet the waterproof requirements of special projects.
本申请的技术方案是：在聚乙烯膜内压入一层金属网做增强网架，在两面复合上纤维层做防滑保护层。The technical scheme of the present application is: press a layer of metal mesh into the polyethylene film to make a reinforced network frame, and compound upper fiber layers on both sides to make an anti-skid protective layer.
本申请的积极效果是由于在主防水层聚乙烯膜内压入一层金属网架，所以大大提高了抗拉强度，即使用低密度聚乙烯，其强度也大大满足特殊工程的施工要求。The positive effect of this application is that a layer of metal grid frame is pressed into the polyethylene film of the main waterproof layer, so the tensile strength is greatly improved. Even if low-density polyethylene is used, its strength can greatly meet the construction requirements of special projects.
图1是本申请的断面结构图。图中1—顶面纤维复合层，2—聚乙烯膜主防水层，3—金属网架，4—底面纤维复合层。Fig. 1 is a cross-sectional structure diagram of the present application. In the figure 1—fiber composite layer on the top surface, 2—main waterproof layer of polyethylene film, 3—metal grid frame, 4—fiber composite layer on the bottom surface.
实施时，顶面纤维复合层1一般可用丙纶无纺布，用于屋面防水保温隔热层时用涤纶无纺布，涤纶无纺布还具有耐热、耐日晒、防腐防虫蛀等优点，所以可免去水泥砂浆保护层；底面纤维复合层4与顶面纤维复合层1相同；聚乙烯膜主防水层2是由聚乙烯材料如低密度聚乙烯与微量化学助剂混合后送入挤出机挤出而成。微量化学助剂用重量0.2—0.5％的抗氧剂1010作主抗氧剂、0.1—0.2％的抗氧剂DLTP作辅抗氧剂、0.5—1.0％的炭黑作补强填充剂。金属网架采用丝径为0.1—0.2毫米，网格为4—25目的钢丝网或铜丝或铝合金网，使卷材既有一定的强度又保持一定的柔性。微量化学助剂中的主抗氧剂1010和辅抗氧剂DLTP由国内北京化工三厂，天津力生化工厂生产，产量大、质量稳定，满足卷材生产要求。During implementation, the top surface fiber composite layer 1 can generally use polypropylene non-woven fabrics, and polyester non-woven fabrics can be used for roof waterproof, thermal insulation, and polyester non-woven fabrics. Polyester non-woven fabrics also have the advantages of heat resistance, sun resistance, corrosion resistance and insect resistance Therefore, the cement mortar protective layer can be removed; the bottom fiber composite layer 4 is the same as the top fiber composite layer 1; the polyethylene film main
生产时，在挤出机上挤出的聚乙烯膜2与金属网3的网卷以及顶、底面纤维复合层1、4同时进入复合辊热压复合。金属网3在聚乙烯膜2内形成增强骨架，复合后冷却收卷形成产品。During production, the
