Preparation method and application of high-strength polymer carbon fiber composite building template

Abstract

The invention discloses a preparation method of a high-strength polymer carbon fiber composite building template, which comprises the following steps: respectively preparing a carbon fiber reinforced resin prepreg layer and a glass fiber reinforced resin prepreg layer, and carrying out staggered stacking at a certain angle to form a reticular staggered structure. The strength and toughness of the whole composite material are effectively enhanced. The used resin adopts thermoplastic resin as a main material, and polycarbonate resin with higher strength is added, so that the impact resistance is good, the refractive index is high, the processability is good, and the UL94V0-grade flame retardant property is achieved without additives; when used in a building template, the used resin has better flame retardant property. The reinforcing agent is selected from a multi-wall nanotube and a modified nano composite material, and has a certain promoting effect on the strength, elasticity, toughness and impact resistance of the building template.

Description

technical field [0001] The invention relates to the field of preparation of carbon fiber composite building templates, in particular to a preparation method of high-strength polymer carbon fiber composite building templates. Background technique [0002] At present, the building formwork used for a long time in the market is wooden, steel formwork and aluminum formwork. Wooden formwork is cheap and easy to use, but it is easy to be scrapped after a short period of use. Besides, in terms of protecting the natural environment, excessive deforestation will cause an imbalance in the natural environment, and storage and transportation are not convenient. Steel formwork and aluminum formwork are not anti-corrosion. It is easy to react with cement, so before the cement is poured, the surface of the steel and aluminum alloy formwork must be painted to prevent corrosion, which is not environmentally friendly and increases the cost.

Wooden formwork is cheap and easy to use, but it is easy to be scrapped after a short period of use. Besides, in terms of protecting the natural environment, excessive deforestation will cause an imbalance in the natural environment, and storage and transportation are not convenient. Steel formwork and aluminum formwork are not anti-corrosion. It is easy to react with cement, so before the cement is poured, the surface of the steel and aluminum alloy formwork must be painted to prevent corrosion, which is not environmentally friendly and increases the cost. Solidify together, thereby deforming or scrapping the formwork when disassembled

[0003] In addition, due to the wider demand for lightweight building materials, carbon fiber materials are very popular due to their own characteristics. Compared with metal materials such as titanium, steel, and aluminum, carbon fiber materials have light weight, high strength, and modulus. High, low density, small linear expansion coefficient, etc., the reinforcing material used as building formwork will significantly improve its performance, but carbon fiber materials also have certain shortcomings. In the preparation process of building formwork, there are usually some high-temperature treatment processes, which will affect carbon fiber. The strength of the material is reduced to a certain extent. How to prepare a high-strength polymer carbon fiber composite building formwork is worth exploring
