preparation example Construction

[0031] In addition, the present invention also provides a preparation method of a halogen-free flame-retardant nylon 66 composite material, comprising the following steps:

[0032] Weigh each component by weight as follows:

[0033]

[0034]

[0035] Among them, the halogen-free flame retardant is a mixture of halogen-free organic phosphine flame retardants and intumescent phosphorus-nitrogen flame retardants;

[0036] After mixing the above-mentioned raw materials except glass fiber evenly, extrude to granulate, and add glass fiber during extrusion, wherein the temperature during extrusion is controlled at 200-250°C.

[0037] The above-mentioned halogen-free flame-retardant nylon 66 composite material is made of nylon 66 resin, halogen-free flame retardant, glass fiber, nucleating agent and other additives through high-temperature extrusion and granulation. The material has a good flame-retardant effect and can reach UL-94. V-0 level, in line with flame retardant requi...

Abstract

The invention relates to a halogen-free flame-retardant nylon 66 composite material. The composite material is prepared from the following components in parts by weight: 53-67 parts of nylon 66 resin, 0.3-0.4 part of coupling agent, 17-21 parts of halogen-free flame retardant, 0.2-0.4 part of nucleating agent, 0.3-0.4 part of antioxidant, 0.2-0.3 part of lubricant and 15-25 parts of fiberglass, wherein the halogen-free flame retardant is a mixture of a halogen-free organic phosphorus flame retardant and an expandable phosphorus-nitrogen flame retardant. The halogen-free flame-retardant nylon 66 composite material is prepared from nylon 66 resin, the halogen-free flame retardant, fiber glass, the nucleating agent and other auxiliary agents by high-temperature extrusion and granulation, thus the material has good flame-retardant effect, can reach V-0 level in UL-94 and meets the flame-retardant requirements; and at the same time, the flame retardant is prepared by mixing the halogen-free organic phosphorus flame retardant and the expandable phosphorus-nitrogen flame retardant, thus the composite material has no pollution, meets the environmental protection requirements, has excellent comprehensive properties and can be widely popularized and applied. In addition, the invention also relates to a preparation method of the halogen-free flame-retardant nylon 66 composite material.

Description

【Technical field】 [0001] The invention relates to the field of polymers, in particular to a halogen-free flame-retardant nylon 66 composite material and a preparation method thereof. 【Background technique】 [0002] Nylon is an excellent engineering plastic with excellent mechanical properties, heat resistance, wear resistance, self-lubrication and good processability. Its application ranks first among the five major engineering plastics and is widely used in automobiles, home appliances, Toys and other related industries. With the rapid development of science and technology, people's requirements for materials are becoming more and more stringent, and the requirements for materials' flame retardancy and environmental protection are getting higher and higher. The application of traditional halogenated flame retardants is limited due to their toxicity. 【Content of invention】 [0003] Based on this, it is necessary to provide an environmentally friendly and non-toxic haloge...
