Problems solved by technology

Most of the published patent technologies use fluorocarbon waterproof additives. Although the best water and oil repellent finishing agents are fluorine-containing organic polymers, most of these additives contain PFOA or its derivatives, which have poor biodegradability. harmful to the environment
In addition, a large amount of volatile organic solvents are used in the formula of this kind of product, which has a pungent taste and is harmful to people when used.

Abstract

The invention relates to fluorine-free anti-splashing spray for fabrics and a preparation method of the fluorine-free anti-splashing spray. The fluorine-free anti-splashing spray is prepared from thefollowing components in parts by weight: 2-25 parts of a fluorine-free waterproof agent, 0.5-15 parts of a crosslinking agent, 1-25 parts of a synergist, 0.05-1 part of s conventional additive, an appropriate quantity of a pH regulator and the balance of deionized water. The fluorine-free anti-splashing water spray for the fabrics is a water-based liquid spray product, is safe to carry and convenient to use, is waterproof and antifouling by slight spraying, is used for waterproof finishing of common synthetic fiber fabrics, shoes and boots, tablecloths, chair covers and other household fabrics, is non-flammable, does not contain harmful VOCs (volatile organic chemicals), fluorocarbon compounds or PFOA, PFOS and APEO, does not have irritating and unpleasant odor and is danger-free, safe andenvironmentally friendly.

Description

technical field [0001] The invention relates to the field of fabric waterproof and antifouling, in particular to a fabric fluorine-free water-repellent spray and a preparation method thereof. Background technique [0002] When the new jacket and trousers are attacked by rainwater, the rainwater will form water droplets on the surface of the clothing and roll down naturally, preventing moisture from penetrating into the fabric. This is DWR (Waterproof Treatment of Jacket). The outer fabric of outdoor fabrics will be treated with DWR to form a non-hydrophilic protective coating to prevent the outer fabric from being soaked and penetrated by water, so as to ensure that water vapor will not adhere to the fabric and will not form a water film, making it reach Surface waterproof effect. However, during the long-term wearing and washing process of the DWR coating, due to the influence of external forces, the adhesive bond will slowly decay until it breaks, the coating active agent...
