preparation example Construction

[0028] The preparation method of the halogen-free flame-retardant high-gloss mineral fiber reinforced PC / ABS material described in this embodiment includes the following steps:

[0029] 1) Drying the mineral fiber material, spraying a silane coupling agent solution on the surface to mix, drying and cooling to obtain a surface-treated mineral fiber material;

[0030] 2) Add the PC, ABS, silsesquisilicone flame retardant, stabilizer, toughening agent, anti-dripping agent, compatibilizer, coupling agent and anti-floating fiber leakage agent into the high-speed mixing In the machine, mix at high speed for 2-10 minutes to obtain the main feed mixture;

[0031]3) Put the above-mentioned main feed mixture into an intermeshing co-rotating twin-screw extruder to melt and extrude, and add the organophosphorus flame retardant and surface-treated mineral fiber materials through side feeding according to the ratio, and melt the reaction , extrusion, cooling, pelletizing, and drying to obt...

Embodiment 1

Abstract

The invention discloses a halogen-free flame-retardant highlight mineral fiber enhanced PC / ABS composite material and a preparation method thereof. The halogen-free flame-retardant highlight mineral fiber enhanced PC / ABS composite material comprises the following components in parts by weight: 35 to 55 parts of PC, 5 to 10 parts of ABS, 0.1 to 0.3 part of a sesquialter silicon flame retardant, 6 to 12 parts of an organic phosphorus flame retardant, 0.1 to 0.3 part of an anti-drip agent, 2.0 to 5.0 parts of a compatilizer, 2 to 5 parts of a toughening agent, 0.1 to 1 part of a stabilizer, 10 to25 parts of mineral fiber material, 0.3 to 1 part of a coupling agent and 0.3 to 0.6 part of a floating fiber leakage preventing agent. The prepared composite material can completely replace a metalmaterial in the aspect of performance, realizes a macromolecular material with highlight effect through the common mold temperature machine and provides more choices for industrial design.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a halogen-free flame-retardant high-gloss mineral fiber reinforced PC / ABS material and a preparation method thereof. Background technique [0002] The substitution of plastics for metals and other traditional materials has become one of the main strategies for product management in many markets. The driving force for replacing metals with plastics is the combination of three elements: cost reduction, design flexibility, and weight reduction. Under the pressure of reducing environmental pollution, energy saving and emission reduction, it is necessary to develop new engineering plastic composite materials to replace metal materials. High-gloss steam injection molding technology helps to promote glass fiber reinforced materials to replace metal materials, but this production process has the disadvantages of long processing cycle, low production effi...
