Problems solved by technology

[0003] In ordinary glass fiber reinforced modified polypropylene (pp) materials, due to the difference in material polar compatibility between PP and glass fibers, floating fibers on the surface, poor material fluidity, and partial warping of the product will appear when forming large-scale products. At the same time, there are defects such as low product strength, low production efficiency and high cost, which have an adverse impact on the promotion and application of products; especially in the context of increasingly large-scale products and complex structures, the products Therefore, using the characteristics of good electrical insulation and high mechanical strength of non-alkali glass fiber, a kind of superfine non-alkali glass fiber cotton and its preparation method for plastic reinforcement are developed to A good solution to the harsh requirements of practical material applications

Abstract

The invention relates to superfine alkali-free glass fiber cotton. The superfine alkali-free glass fiber cotton is prepared from, by weight, 80-90% of superfine alkali-free glass fiber and 10-20% of adhesive assistant; the superfine alkali-free glass fiber is prepared from, by weight, 55-59% of SiO2, 13-18% of Al2O3, 2.5-4.5% of MgO, 15-24% of CaO, 0-0.5% of Na2O, 0-0.3% of K2O, 0.15-0.4% of Fe2O3, 6-8.5% of B2O3 and 0.5-1.5% of TiO; the total content of alkaline metal oxide Na2O and k2O is smaller than 0. 6%, and the sum of the contents of SiO2, Al2O3, MgO and CaO is greater than 92.5%. The invention further relates to a preparation method of the superfine alkali-free glass fiber cotton, the superfine alkali-free glass fiber is light in weight and supper thin and uniform in diameter, and has excellent mechanical performance.

Description

technical field [0001] The invention belongs to the technical field of functional composite materials, and relates to a preparation method of ultrafine alkali-free glass fiber cotton. Background technique [0002] Alkali-free glass fiber refers to aluminoborosilicate with an alkali metal oxide content of less than 1% in the fiber composition. It has a series of excellent properties such as good electrical insulation, high temperature resistance, corrosion resistance, high mechanical strength, light specific gravity and water resistance. , which is incomparable to other functional materials and structural materials. Alkali-free glass fiber is the best basic functional material for the development of modern industry, agriculture, national defense and cutting-edge science; at the same time, because the alkali-free glass fiber has less alkali metal content, its dielectric constant is only about 6.5, which can be mainly used for Reinforcement materials for electronic circuit boa...
