Problems solved by technology

[0005] Due to the frequent occurrence of car accidents and fire incidents, the flame resistance of car body parts and various building material partitions has also received high attention. In addition, it is known that the interior parts and partitions used to make interior parts and partitions contain a large amount of extremely flammable matrix resin. If only the existing coating method is used to coat the flame retardant on the surface, the coating may peel off due to external impact, and the purpose of isolating the fire source will not be achieved. Therefore, if the prepreg itself can be equipped with flame resistance, it should be more beneficial Let the industry make various flame-resistant materials

Embodiment

[0027] (Chemicals)

[0028] Following examples and comparative examples use following chemicals respectively:

[0029](1) Epoxy resin: A combination of bisphenol A type epoxy resin (Epikote 1001 and Epikote 828), bisphenol F type epoxy resin (Epikote 862) and novolak type epoxy resin (Epikote 154) was used.

[0030] (2) Inorganic flame retardant: use ammonium polyphosphate (S-20).

[0031] (3) Thermoplastic resin: use PKHH and

[0032] (4) Hardener: use DDS.

[0033] (5) Reinforcing material: Embodiment 1~4 and comparative example 1 are to use carbon fiber (Toho Tenax HTS-12K, manufactured by Japan Toray Company), the tensile strength of this carbon fiber is 4300MPa, tensile modulus is 238GPa, Elongation (elongation) is 2.1% and density is 1.8g / cm 3 . Embodiment 5 is to use carbon fiber 3K plain weaving woven cloth (Toray CO6343, manufactured by Japan Toray Company), this carbon fiber woven cloth is woven by T300-3K fiber, and its tensile strength is 3530MPa, and tensil...

Abstract

The invention discloses prepreg with flame retardance; the prepreg contains a reinforcing material and a flame retardance compound. The reinforcing material is selected from reinforcing fiber or reinforcing fabric; the epoxy equivalent value of the flame retardant compound is between 190g / eq to 270g / eq, and the flame retardant compound is provided with epoxy resin, inorganic flame retardant, thermoplastic resin and hardener, wherein, calculated by 100 weight percent of the total weight of the flame retardant compound, the content of the inorganic flame retardant is 12 weight percent to 18 weight percent. The prepreg with flame retardance of the invention is applicable in manufacturing the inner parts of all transportation tools or all buildings materials, partition boards, etc.

Description

technical field [0001] The invention relates to a prepreg, in particular to a prepreg with flame resistance. Background technique [0002] Fiber composite materials have been widely used in the manufacture of various sporting goods (such as golf clubs, fishing rods, tennis racket frames, etc.), transportation tools, etc. Most of the fiber composite materials are made by continuous lamination of a plurality of prepregs (prepreg) [also known as sheet-like intermediate material, mainly composed of a reinforcing fiber and a matrix resin], and this prepreg is borrowed It is prepared by impregnating the reinforcing fiber into the matrix resin, so the type and content ratio of the reinforcing fiber and matrix resin will affect the properties of the prepreg, such as tackiness, tensile strength, shear Shear strength, flexural strength, etc. [0003] U.S. Patent Publication No. 6,287,696 discloses a prepreg comprising a plurality of reinforcing fibers and a resin composition, the re...
