Embodiment 1

[0048] Example 1: Ultra-thin waterproof fabric 1:

[0049] An ultra-thin waterproof fabric, the fabric components are by weight:

[0050] The weight fraction of modified polystyrene A is 50 parts, the weight fraction of modified polystyrene B is 10 parts, the weight fraction of acrylic acid is 5 parts, the weight fraction of benzyl alcohol is 5 parts, and the weight fraction of bridging agent is 5 parts. The weight fraction of sugar is 5 parts, and the weight fraction of NMMO solution is 50 parts.

[0051] The preparation method of this fabric is as follows:

[0052] (1) Polystyrene is fully dissolved in the mixed solution of ethyl acetate and cyclohexane, the volume ratio of ethyl acetate and cyclohexane is 3:1, the temperature is raised to 85°C, and it is transferred to a In a four-necked flask with a stirrer, a thermometer, and a condenser, after stirring for 5 minutes, add benzoyl peroxide as an initiator, and then dropwise add a mixed monomer composed of acrylic acid an...

Abstract

The invention discloses an ultrathin and waterproof fabric and a preparation method thereof. Two monomers of acrylic acid and benzyl alcohol are used for carrying out chemical grafting modification on polystyrene, so that the acting force between the fabric and a microporous membrane is enhanced, and the microporous membrane is prevented from falling off; the fabric is subjected to plasma treatment, rough pits are formed in the surface, and the pits form a closed space through the microporous membrane, so that the weight of the fabric is reduced, and the toughness of the fabric is enhanced while the waterproof performance of the fabric is enhanced; chitosan is used for carrying out in-situ modification on modified polystyrene, and a bridging agent is added after modification, so that the fabric has waterproof ability and air permeability, and the inner sides of double-layer fabrics are tightly combined and have antibacterial property; and during preparation, heating and drying are performed twice, first heating and drying enable the modified polystyrene A on the surface of superfine fiber to uniformly form the membrane, and second heating and drying enable the prepared fabric to be lighter and thinner and higher in wearability.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to an ultra-thin waterproof fabric and a preparation method thereof. Background technique [0002] At present, waterproof and breathable fabrics have become a hot spot in the research and development of textile products in various countries. With the wide application and continuous extension of such products in military, medical, civilian and other industrial fields. With the continuous development of the times, people's requirements for the quality of life are getting higher and higher. For waterproof fabrics, only waterproofing can no longer meet the current needs. [0003] Today's waterproof fabrics have a multi-layer waterproof structure to achieve a waterproof effect. The result of multiple layers is often too thick and cannot play a role in some special areas. Therefore, research on ultra-thin and waterproof fabrics is very promising. Therefore, it is very necessary to prepare a kind ...
