Abstract

The invention discloses a preparation method of a waterproof and moisture-permeable raincoat, wherein the preparation method comprises the following operation steps: (1) mixing methyl methacrylate, isobutyl methacrylate, ethyl dimethacrylate, an initiator, 2,3,3-trifluoroacrylic acid, deionized water and an emulsifier evenly, heating, and carrying out heat preservation, to prepare a polymerized emulsion; (2) adding dysprosium chloride and lutetium chloride to water, continuing to add sodium naphthenate, mixing and stirring evenly, heating to 65-70 DEG C, and after 2-3 h of heat preservation treatment, obtaining rare earth naphthenate; and (3) mixing the polymerized emulsion, dimethyl polysiloxane, a polyoxyethylene castor oil condensate and rare earth naphthenate evenly, preparing a raincoat coating, and then coating the surface of the woven raincoat with the raincoat coating, and carrying out drying treatment, to obtain the finished product. The prepared raincoat has the advantages ofgood softness, easy folding, excellent water resistance and moisture permeability, excellent oxidation resistance and long service life.

Description

technical field [0001] The invention belongs to the technical field of raincoat preparation, and in particular relates to a preparation method of a waterproof and moisture-permeable raincoat. Background technique [0002] Raincoats generally refer to rainproof clothes made of waterproof fabrics. The waterproof fabrics suitable for raincoats include tapes, tarpaulins and plastic films. As we all know, raincoats with better waterproof performance are either expensive or sweltering when worn. In order to overcome these two points, British researchers developed an organotin compound. After the fabric is soaked in this compound, it is both waterproof and very stiff. The inorganic group of this compound is connected in the fiber of the fabric, and the organic group is exposed outside the fabric, playing a hydrophobic role. This research result can replace the traditional method of waxing and brushing resin on the cloth, and also avoids special treatment of the fibers to be wov...
