Problems solved by technology

However, for special types of coiled materials, the tire base fabric only meets the requirements of the national standard, which is not enough to reflect the characteristics of special coiled materials. In particular, problems such as thermal deformation will occur during the production process, resulting in unqualified coiled products and affecting the waterproof effect of construction.

The adhesive comprises the raw materials of, by mass, 2-4.5g of nonylphenol ethoxylate (NP-40), 1-2g of n-methylol acrylamide, 0.5g of monobutyl itaconate, 1-1.5g of acetoacetic ethyl methacrylate, 0.5-1.5g of lauryl sodium sulfate, 0.5-1g of acrylic acid, 2-7g of styrene, 24-36g of acrylate, 0.2-0.8g of ammonium persulfate, and 49-76.2g of deionized water.

Description

technical field [0001] The invention relates to a heat-stable acrylic adhesive for waterproof coiled base cloth and a preparation method thereof. Background technique [0002] Non-woven fabrics are also called non-woven fabrics. The national standard GB / T5709-1997 "Textile Non-woven Fabric Terminology" defines non-woven fabrics as: oriented or randomly arranged fibers, through friction, cohesion, or bonding, or by these methods Sheets, webs or batts made in combination, excluding paper, woven, knitted, tufted and wet milled felts. Nonwovens have broken through the traditional woven or knitted textile principles, and are widely used in medical and health care, home decoration, clothing, industry, agriculture, etc., with short process flow, fast production speed, high output, low cost, and wide application. There are many sources of raw materials and so on. [0003] The base fabric of the waterproof membrane is a polyester non-woven fabric. In order to meet the thermal dimen...
