Abstract

The invention relates to the technical field of garments and discloses a waterproof protective garment comprising a one-piece garment body. The surface of the one-piece garment body is treated with awaterproof finishing agent, and the waterproof finishing agent comprises the following components in parts by weight, including 20-30 parts of hydroxyl silicone oil, 10-15 parts of lauryl sodium sulfate, 5-6 parts of dimethyl malonate; 2-4 parts of glutaraldehyde and 60-80 parts of deionized water. The waterproof protective garment has the following advantages and effects that the hydroxyl silicone oil can endow clothes with water resistance and water repellency; the mixed emulsion of the hydroxyl silicone oil and the lauryl sodium sulfate enables a layer of hydrophobic film formed on the surface of the one-piece garment body, so that the surface tension is reduced, water and oil are difficult to wet the surface of the one-piece garment body, and the oil-repellent and water-repellent effects are achieved; the dimethyl malonate has a strong electron withdrawing group and is prone to having a similar aldol condensation reaction with the glutaraldehyde to achieve the purpose of increasinga carbon chain, and the number of carbon atoms of the mixed component is increased, so that the thickness of a hydrophobic layer formed on the surface of the protective garment is increased, the surface tension is reduced, and the hydrophobicity and the waterproof effect are improved.

Description

technical field [0001] The invention relates to the technical field of clothing, in particular to a waterproof protective clothing. Background technique [0002] Protective clothing is mainly used in industries and departments such as fire protection, military industry, shipbuilding, petroleum, chemical industry, painting, cleaning and disinfection, and laboratories. Operators need to wear protective clothing in these working environments to isolate the human body from the external environment and keep the wearer hygienic. [0003] At present, the patent with publication number CN111000302A discloses a protective clothing, including protective clothing and protective pants. The top of the protective clothing is cut into one body with a protective cap. The elastic cuffs are connected, and the outer surfaces of the two elastic cuffs are sewn with a first elastic band, and the trousers of the protective pants are connected with elastic trousers; the raw materials of the protec...
