Abstract
The invention provides a method for producing anti-tearing airtight cloth, which includes steps of weaving skeletal material by using high-strength synthetic fiber with 280D-600D as warp and woof; coating a resin layer on at least one surface of the pretreated skeletal material by a gap coating combination transfer coating method, wherein the resin includes 85-90 parts of thermoplastic resin, 1-5 parts of nano inorganic additive, and 5-10 parts of organic modifier; and sorting to obtain the anti-tearing airtight cloth. For the airtight cloth, surface density is less than or equal to 280g / m<2>, radial incision tear intensity is more than or equal to 235N, latitudinal incision tear intensity is more than or equal to 220N, peeling strength is more than or equal to 2310N / m, and helium permeation ratio is less than or equal to 1L.(m<2>.24h.1atm).
Description
1. Technical field [0001] The invention relates to a production method of an anti-tear airtight cloth. 2. Background technology [0002] At present, the flexible anti-tear frame material is mainly made of polyester, nylon or other fibers after weaving, and coated with PVC, etc., which involves environmental protection issues of plasticizers. The processing technology is complex, the surface density of the material is high, the temperature resistance and weather resistance are poor, especially the low temperature resistance, easy to fold, damage, air leakage, and poor tear resistance, etc., which cannot meet the needs of high-performance materials. The anti-tear airtight cloth material can be realized by dipping, coating, lamination bonding, film compounding, extrusion coating and other processes. Due to the complicated process (coating, sizing, lamination, etc.), the technical content is high, High added value and broad market prospect. 3. Contents of the invention [00...
