preparation example Construction

[0070] The preparation method of maleic anhydride graft modified polypropylene in the present invention is not particularly limited, it can be commercially available, or can be obtained by solution method, supercritical CO 2 It can be synthesized by methods well known to those skilled in the art such as solution method, melting method, radiation method and solid phase method.

[0071] For example, the maleic anhydride graft-modified polypropylene is prepared by the melting method: mix styrene and the initiator dicumyl peroxide, dissolve, and make a styrene solution of the initiator. Mix polypropylene and maleic anhydride into a mixture, feed the mixture of polypropylene and maleic anhydride into the twin-screw extruder, after it melts, put the styrene solution of the initiator in different screw barrel sections of the twin-screw extruder Continuous metering input, melt grafting reaction, to obtain maleic anhydride graft modified polypropylene.

[0072] In the maleic anhydride...

Abstract

The invention relates to the field of high polymer materials, and particularly discloses an anti-flaming polyamide composite material with good printing performance. The anti-flaming polyamide composite material is prepared from the following raw materials in parts by weight: 30 to 90 parts of polyamide resin, 1 to 20 parts of polybenzimidazole, 3 to 15 parts of ethylene-vinyl acetate copolymer, 1 to 10 parts of SEBS (Styrene-Ethylene-Butylene-Styrene Block Copolymer), 1 to 15 parts of maleic anhydride modified polypropylene, 1 to 15 parts of cyclodextrin-polyethylene glycol composite, 1 to 10 parts of liquid paraffin, 1 to 10 parts of filler, 0.5 to 1 part of brominated flame retardant and 0.5 to 3 parts of synergistic flame retardant.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant nylon composite material with good printing performance and a preparation method thereof. Background technique [0002] Nylon, also known as polyamide (PA), is the variety with the largest output, the most varieties, and the widest application among the five major engineering plastics. Polyamide has good comprehensive properties, such as mechanical properties, heat resistance, wear resistance, cold resistance, corrosion resistance, chemical resistance, non-toxicity, self-lubrication and easy molding process. Therefore, it can be widely used in mechanical construction, auto parts, electronic devices, chemical equipment, aviation, metallurgy and other fields. [0003] Nylon has excellent comprehensive properties such as excellent mechanical properties, heat resistance, wear resistance, and chemical corrosion resistance, and is widely used in the fields of machine...
