Description

technical field [0001] The invention relates to the field of glass fibers, in particular to a preparation process of an acid and alkali-resistant glass fiber composite material. Background technique [0002] Alkali-resistant glass fiber, also known as alkali-resistant glass fiber, was invented by a doctor of the British Institute of Building Research, and developed and industrialized in the 1970s in cooperation with the British Pilkington Glass Company to produce products, mainly used to strengthen cement In concrete, it can effectively resist the erosion of alkaline substances in cement concrete. Due to the characteristics of light weight, high strength, non-combustibility, high temperature resistance, corrosion resistance of alkali substances, strong designability, and easy molding, alkali-resistant glass fibers are used in non-load-bearing The structure can replace steel bars to enhance the tensile strength of cement concrete, so the research and development and applicati...

[0002] Alkali-resistant glass fiber, also known as alkali-resistant glass fiber, was invented by a doctor of the British Institute of Building Research, and developed and industrialized in the 1970s in cooperation with the British Pilkington Glass Company to produce products, mainly used to strengthen cement In concrete, it can effectively resist the erosion of alkaline substances in cement concrete. Due to the characteristics of light weight, high strength, non-combustibility, high temperature resistance, corrosion resistance of alkali substances, strong designability, and easy molding, alkali-resistant glass fibers are used in non-load-bearing The structure can replace steel bars to enhance the tensile strength of cement concrete, so the research and development and application of glass fiber reinforced cement have developed rapidly in developed countries above the middle level. In addition, glass fiber is an inorganic non-metallic material with excellent performance. Its insulation, Good heat resistance and corrosion resistance, high mechanical strength, acid and alkali resistance, rigidity, anti-aging, and oxidation resistance of existing glass fiber composite materials need to be improved. Among many polymer composite materials, fiber reinforced composite materials are due to It has excellent comprehensive properties, and glass fiber has good corrosion resistance, heat resistance, good mechanical strength, and low raw material prices, etc., and is widely used in composite materials for reinforcement purposes. It is made by blending two or more materials together through an auxiliary method. There is often a phase interface between the materials due to different properties, which will eventually lead to the change of the shear force between the interface layers and lead to the failure of the composite material. poor performance
