Preparation method of anti-aging polypropylene fiber

Abstract

The invention relates to a preparation method of anti-aging polypropylene fiber, and belongs to the technical field of functional fiber preparation. According to the method, wollastonite raphioid fiber, aluminum borate whisker, concave-convex rod crystals, sodium bicarbonate water solution and nano-montmorillonite are mixed and stirred; then, the materials are soaked into a sulfamic acid solution for heating, stirring and dispersing; suspended solids are taken to be subjected to ultrasonic treatment; then, upper layer suspended solids are taken to be filtered, washed and dried; obtained materials are mixed with the aluminum borate whisker, PP-g-MAH, silane coupling agents, ultraviolet absorbents, light stabilizers and antioxidants; the obtained mixture is stirred and dried; isotatic polypropylene is added; the mixture is stirred; fusion compounding is performed to prepare the anti-aging polypropylene fiber. The preparation method has the advantages that the defects in the prior art are overcome; the aluminum borate whisker, the PP-g-MAH, the wollastonite raphioid fiber, the ultraviolet absorbents, the light stabilizers and the antioxidants are added in the isotactic polypropylene; the blending fusion is performed with the isotactic polypropylene to prepare the sheath core type anti-aging polypropylene fiber using the anti-aging polypropylene as a sheath layer.

Description

technical field [0001] The invention relates to a preparation method of anti-aging polypropylene fiber, which belongs to the technical field of functional fiber preparation. Background technique [0002] Polypropylene fiber or PP fiber is a fiber melt-spun from isotactic polypropylene. Its biggest advantage is light weight and a density of 0.91 / cm 3 , 20-30% lighter than ordinary chemical fibers, is the smallest specific gravity of all textile fibers, high strength, large elongation, high initial modulus, and excellent elasticity. The abrasion resistance of polypropylene fiber is second only to that of polyamide fiber, and it has good corrosion resistance, especially for inorganic acid and alkali stability, no mildew, no rot, and no fear of insects, etc. , such as various furniture cloths, decorative cloths, advertising cloths, carpets, bags, tents, geotextiles, cables, fishing equipment, packaging materials and filter cloths, etc., but polypropylene fibers do not absorb wa...

Problems solved by technology

The abrasion resistance of polypropylene fiber is second only to that of polyamide fiber, and it has good corrosion resistance, especially for inorganic acid and alkali stability, no mildew, no rot, and no fear of insects, etc. , such as various furniture cloths, decorative cloths, advertising cloths, carpets, bags, tents, geotextiles, cables, fishing equipment, packaging materials and filter cloths, etc., but polypropylene fibers do not absorb water, are difficult to dye, and have a lot of static electricity. And low temperature, due to the high regularity of its molecular structure, so the impact strength is poor

Polypropylene fiber is very sensitive to ultraviolet rays, easy to age, and has poor flame resistance. Due to its non-hygroscopic, airtight, uncomfortable, poor thermal stability, and easy to absorb dust, it is not suitable for clothing
