Abstract

The invention provides a polyborosiloxane modified fiber and a preparation method thereof. The preparation method comprises the steps that any one of polycaprolactam, polyhexanediamine adipate, polylaurolactam, a thermoplastic polyester elastomer and thermoplastic polyurethane is obtained to serve as a raw material, and polyborosiloxane is obtained; a mixture of the raw material and the polyborosiloxane is subjected to banburying to obtain a to-be-treated material; the to-be-treated material is cut into particle particles, the particle particles are heating to be melted, and a flat die is prepared; and the fiber is prepared from the flat die to obtain the polyborosiloxane modified fiber. The polyborosiloxane is added into a wiredrawing material, non-covalent bonds of the raw material can be reversibly broken and regenerated, a large amount of external energy is absorbed, meanwhile, molecular chain movement is intensified, and the strength of the wiredrawing material can be improved. When a wiredrawing product has high elongation, high relative tensile strength can be maintained, and the elongation of a monofilament can also be greatly improved. When the fiber is made into shoes andclothes, a fabric is stiff and smooth and is not easy to deform under high-speed impact.

Description

technical field [0001] The invention relates to the technical field of preparation methods of polymer composite materials, in particular to a polyborosiloxane modified fiber and a preparation method thereof. Background technique [0002] Drawing process is an important plastic molding process, which can be used to produce linear plastic products and plastic woven products such as woven bags, colored strips, carpet backing, container bags, tarpaulins, ropes, etc. Its products have good moisture resistance, It has the advantages of good corrosion resistance, mildew resistance, abrasion resistance and long service life. It is mainly used in the packaging field, and can be used to package grain, chemical fertilizers, cement, sugar, salt, industrial materials and ore, etc. [0003] In the existing wire drawing process, the raw material is usually TPU or TPE, and the supported wire drawing product has relatively low tensile strength under the condition of high elongation, and is e...
