Abstract

The invention relates to the technical field of natural rubber materials, and concretely relates to a preparation method of a natural antibacterial latex liner for underwear. The preparation method comprises the following steps: mixing natural rubber with water, adding a supramolecular solvent to the mixed solution, removing proteins, and performing freeze drying to obtain a natural latex; dissolving chitosan in an acetic acid-water mixed solution, adding natural latex, nano-cellulose, an inorganic filler, glutaraldehyde and a silane modifier, carrying out a reaction, filtering the obtained solution, and performing freeze drying to obtain a natural latex master batch; and performing high-speed stirring and mixing on the natural latex master batch, a natural antibacterial agent, an oxidant,nano-silica and a punching agent, heating and melting the obtained mixture at 100-150 DEG C, injecting the melted mixture into a grinding tool, carrying out curing molding, keeping the temperature at60-75 DEG C for 2-4 h, and cooling, washing and drying the cured mixture to obtain the natural antibacterial latex liner for underwear. The method of the invention is simple to operate, and the prepared latex liner has the advantages of soft texture, excellent mechanical properties, good air permeability and good antibacterial and anti-oxidation properties.

Description

technical field [0001] The invention relates to the technical field of natural rubber materials, in particular to a preparation method of a natural antibacterial latex pad for underwear. Background technique [0002] Natural latex is milky white liquid that flows out from rubber trees of a certain age when they are tapped. Fresh natural latex mainly contains rubber, protein, natural resin, sugar and so on. As a renewable polymer material, natural latex is favored by the rubber industry due to its rich sources and cheap price, anti-mite and anti-bacterial properties, good air permeability, excellent film-forming properties, elasticity and mechanical properties. At present, natural latex is mainly used to make sponge products, extruded products and impregnated products. The natural latex raw material is very soft, which makes latex an ideal material for clothing, especially underwear. But natural latex has many nutrients, although the natural components in the latex have ce...
