AI Technical Summary

Problems solved by technology

Due to the surface properties of the glass fiber, the degree of modification is shallow, and even the modification can only partially modify the surface of the glass fiber. The amount of modifier used is large, not to mention wasting resources, and the effect obtained is often incomplete. As one wishes

[0024] Weigh the corresponding formula according to the formula shown in Table 1, and prepare according to the following steps:

[0025] (1) Immerse the glass fibers in hydrofluoric acid for 10-40 seconds, wash and dry, and set aside;

[0026] (2) Add an appropriate amount of glass fiber, methoxyvinyldimethylsilane, tetrahydrofuran and hydrochloric acid obtained in step (1) into a reaction vessel, and react at 30-70°C for 1-5 hours to obtain a vinyl-containing modified permanent glass fiber material;

[0027] (3) The modified glass fiber material, azobisisobutyronitrile, and vinyl chloride monomer of step (2) are polymerized in a reactor to obtain a glass fiber / PVC composite material;

[0028] (4) the composite material that step (3) obtains and 100 mass parts polyvinyl chloride, 20 mass parts nanometer calcium carbonate, 20 mass parts dioctyl sebacate, 4 mass parts stearic acid, 1.5 parts of tribasic, two 1.5 parts of alkali are stirred in a stirred tank, cooled to a suitab...

Abstract

The invention discloses high-strength glass fiber modified PVC (polyvinyl chloride) door and window profile and a preparation method thereof. Glass fibers are modified from the perspective of chemicalmodification, so that cohesiveness between the glass fibers and a substrate interface can be better, and one composite material which is improved in overall performance such as impact strength, tensile strength, wear resistance and the like is obtained and has great economic and social value when applied to the door and window profile with high strength and high wear resistance.

Description

technical field [0001] The invention relates to a high-strength glass fiber modified polyvinyl chloride composite door and window profile, in particular to the production and preparation method of the high-strength and wear-resistant composite material in the door and window profile. Background technique [0002] Polyvinyl chloride (PVC) is one of the commonly used polymer materials in the chemical and chemical industry. PVC is a white powder with an amorphous structure, with a small degree of branching, a relative density of about 1.4, and a glass transition temperature of 77-90°C. Decomposition, poor stability to light and heat, above 100°C or after long-term sunlight exposure, it will decompose and produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties, must be added in practical applications Stabilizers to increase stability to heat and light. The molecular weight of industrial...
