摘要： The present invention provides a polyamide composite material, which includes the following components in parts by weight: 25-85 parts of a polyamide resin; 10-50 parts of a glass fiber; 5-25 parts of polytetrafluoroethylene; and 0.1-2 parts of at least one of a K/Na/Ca/Mg/Ba/Zn/Li/Al salt of montanic acid. The montanate can effectively inhibit free hydrogen fluoride in the polytetrafluoroethylene, thereby effectively inhibiting free silicon in the glass fiber and improving the electrical performance of the material.

摘要： The present invention provides a polyamide composite, including the following components: 20 to 80 parts of a polyamide resin; 1 to 30 parts of a red phosphorus flame retardant; 0.01 to 10 parts of trimethallyl isocyanurate; and the polyamide composite has a cross-linked structure between polyamide molecules. By adding trimethallyl isocyanurate (TMAIC) for irradiation cross-linking treatment, and by the red phosphorus flame retardant, not only the polyamide composite can meet the needs of flame retardant, but also glow-wire ignition temperature (GWIT) and comparative tracking index (CTI) have been improved.

摘要： The present invention relates to a flame-retardant nylon composite and use thereof, including components: 55 parts to 80 parts of a nylon resin; 1 part to 30 parts of a red phosphorus; and 0.01 part to 2 parts of a phenolic substance. According to the present invention, by adding a small amount of the phenolic substance to the red phosphorus flame-retardant nylon composite, phosphorus precipitation can be effectively inhibited, and a phosphine precipitation amount can be reduced to 30 ppm or less, while good electrical performances can be maintained, which is applicable in fields of connectors, contactors, etc. in electronic appliances.

摘要： The present invention provides a polyformaldehyde composite material, in parts by weight, including the following components: 70 to 95 parts of a polyformaldehyde; 5 to 20 parts of a SEBS; wherein, the SEBS is acid modified or amine modified. Due to modification by acid or amine, and presence of a polystyrene segment, a compatibility of the SEBS with the polyformaldehyde reduces because of a steric hindrance effect, which reduces an ability of a POM molecular chain to arrange regularly. When injection molded into a product or template, an incompatibility of the material itself will form a micro-rough effect on a surface of the material. When an incident light reaches the micro-rough surface, a reflection direction of the light will change and thus a diffuse reflection occurs, and a low-gloss material is obtained.
