Problems solved by technology

[0003] At present, the materials of high-performance resin composite materials used in domestic and foreign fields are relatively single, mainly unsaturated polyester, vinyl ester resin, and tough epoxy resin materials, but these materials have deficiencies to varying degrees.
Such as unsaturated polyester, high brittleness, low use temperature, and low bonding strength; although vinyl ester resin has the advantages of good toughness, good bonding strength, and low toxicity after curing, it has disadvantages such as low use temperature; epoxy resin , although it has the advantages of good toughness and high bonding strength, it has poor weather resistance, easy pulverization, high viscosity, and poor wettability. Poor, the curing system is highly toxic, the curing cycle is long, and the post-processing cost is high.
Therefore, traditional composite materials are far from meeting the market's increasingly high performance requirements.

Embodiment 1

[0008] Embodiment 1: A kind of flame retardant resin of the present invention, each raw material component is weighed according to the following weight ratio: unsaturated polyester resin 50%, clay fiber 10%, copper naphthenate 5%, cobalt isooctanoate 2% , calcium carbonate 20%, polyvinyl fluoride 5%, silicon dioxide 8%.

[0009] The preparation method of this flame retardant resin, its concrete steps are as follows:

[0010] 1. Take 50% unsaturated polyester resin and add it to the barrel, then add 10% clay fiber, 5% copper naphthenate, 2% cobalt isooctanoate, 20% calcium carbonate, 5% polyvinyl fluoride and 8 % of silica;

[0011] 2. Stir the above raw materials with a mixer for 30 minutes until the raw materials are completely uniform; the flame retardant resin can be made.

Embodiment 2

[0012] Embodiment 2: A kind of flame-retardant resin of the present invention, each raw material component is weighed according to the following weight ratio: unsaturated polyester resin 45%, clay fiber 11%, copper naphthenate 7%, cobalt isooctanoate 4% , calcium carbonate 22%, polyvinyl fluoride 2%, silicon dioxide 9%.

[0013] The flame retardant resin can be obtained according to the above preparation method.

Abstract

The invention discloses a flame-retarded resin. The flame-retarded resin comprises the following components in percentage by weight: 45-60% of unsaturated polyester resin, 10-20% of clay fiber, 5-8% of copper naphthenate, 2-5% of cobalt iso-octoate, 20-30% of calcium carbonate, 1-5% of polyvinyl fluoride and 8-12% of silicon dioxide. The flame-retarded resin has good permeability on a variety of fiber products due to small viscosity and good wetting property, is adjustable in viscosity and long in service cycle, can be widely applied to processes of mechanical winding, casting, manual pasting, die pressing and the like, and has a wide market value and a huge market potential.

Description

technical field [0001] The invention relates to the technical field of polymer materials, more specifically, it is a flame-retardant resin. Background technique [0002] With the continuous development of corrosion and protection and the improvement of industrialization, the application fields of composite materials are becoming wider and wider. The working conditions and media are becoming more and more complex, and the operating temperature is getting higher and higher. The market requirements for its performance are also increasing. Higher and higher. [0003] At present, the materials of high-performance resin composite materials used in domestic and foreign fields are relatively single, mainly unsaturated polyester, vinyl ester resin, and tough epoxy resin materials, but these materials have deficiencies to varying degrees. Such as unsaturated polyester, high brittleness, low use temperature, and low bonding strength; although vinyl ester resin has the advantages of go...
