Glass fiber composition

Abstract

The invention discloses a glass fiber composition. The glass fiber composition consists of the following raw materials in parts by weight: 40-70 parts of polyethylene powder, 10-20 parts of phenolic resin, 1-5 parts of fatty acid polyglycol ether, 2-4 parts of ferric oxide, 20-40 parts of a silane coupling agent, 2-6 parts of a color masterbatch, 1-5 parts of phosphorous acid, 1-3 parts of sodium hexametaphosphate, 2-4 parts of ethylene glycol, 1-3 parts of bamboo fiber mat, 4-10 parts of barium titanate powder, 1-3 parts of sodium carbonate, 1-3 parts of quicklime, 4-6 parts of quartz powder, 1-3 parts of borocalcite and 2-4 parts of magnesium oxide. The glass fiber composition has the advantages of light weight, high strength and high-temperature resistance; the dielectric constant of the formula is increased through barium titanate powder; a preparation method of the glass fiber composition is simple in process and can be implemented on conventional equipment; and meanwhile, the glass fiber composition is high in strength, rigidity and impact toughness, simple in process, low in cost and high in production efficiency.

[0002] With the development of the battlefield environment, in order to improve the battlefield survivability of tactical missiles and effectively suppress and destroy enemy air defense or early warning systems, the flying speed of missiles is getting faster and faster, and the range is getting farther and farther. Therefore, tactical missiles have begun to put forward more weight requirements. Due to the high density and poor toughness of the material itself, the weight of the product is relatively high. The use of resin-based composite materials in the radome can greatly reduce the cost of the radome. weight; but most resin-based composite materials have poor temperature resistance, so the range of use is small. With the continuous enhancement of "ecological awareness", people pay more and more attention to environmental protection and health. Among them, excellent processing performance, The environmental pollution caused by plastics used in various industrial products has become a common concern. In particular, fiber-reinforced composite materials are usually composed of glass fibers, carbon fibers, etc. and plastics. Disposal is difficult and the production environment is harsh. It has added a great burden to the environment. Therefore, natural fibers such as bamboo, hemp, and wood fibers have attracted people's interest in development and application because of their light weight, low price, easy availability, biodegradability, and no pollution to the environment. Although the surface of glass fiber is generally treated with soda ash, since polypropylene is a non-polar polymer material, the interface bonding strength with glass fiber is poor, even if some acid anhydride grafted polypropylene is usually used to improve the interface bonding strength , but the improvement of the performance of polypropylene by glass fiber modification is still limited
