Produce.
The invention has the advantages that：
1st, rigid acetal resin and esters of acrylic acid toughener are pre-mixed in 100-200 degree, prepare acrylic acid
Ester carries POM master batch, equivalent to being diluted processing to POM.This pre-mixed resin is added in polyester alloy material afterwards, passed through
The immixture of twin-screw extrusion is effectively disperseed.Highly-efficient lubricant is added in melt, on the one hand improves the surface of material
Coefficient of friction, improve plastic wear-resisting；On the other hand in process, increase the mobility of melt, reduce the viscosity of melt
And melt temperature, prevent acrylate to carry POM master batches and degraded under high melt temperature.
2nd, compared with prior art, this kind of rub resistance flame retardant polyester alloy provided by the present invention, utilizes acrylic resin
Efficient toughness reinforcing and support, the high-crystallinity POM similar to rigid particles is pre-processed.With highly-efficient lubricant,
PTFE reduces the melt temperature in the coefficient of friction and process on surface.Effectively POM is caused to be distributed in flame retardant polyester alloy
In, on the basis of polyester alloy keeps fire-retardant and main physical property, anti-wear performance is significantly improved.
