Abstract
The invention discloses masterbatch for plastic. The masterbatch comprises the following components in parts by weight: 45-65 parts of methyl methacrylate copolymer, 20-50 parts of inorganic or organic pigment and 0.5-1.5 parts of silane coupling agent. The invention also provides a preparation method of the masterbatch for the plastic. According to the invention, the high-property methyl methacrylate copolymer is used as a base material of the masterbatch, and inorganic or organic pigment and a small amount of silane coupling agents are added for carrying out blending extrusion and granulation, so that the masterbatch with good high temperature resistance and good mechanical property is obtained.
Description
[technical field]
The present invention relates to a kind of Masterbatch, particularly a kind of plastic cement Masterbatch and preparation method thereof.
[background technology]
Present plastic cement is generally used PC (Polycarbonate, polycarbonate), particles such as ABS (Acrylonitrile-Butadiene-Styrene, acrylonitrile-butadiene-styrene copolymer), the PC/ABS base-material as the look mother with Masterbatch.Yet, for the PC and PC/GF (Glass Fiber, the glass fibre) product of high-temperature molding, use the Masterbatch of particles such as PC, PC/ABS, ABS as base-material, at high temperature can cause part to be decomposed, influence the product mechanical property of making, thereby influence the outward appearance and the yield of product.
[summary of the invention]
In view of this, the object of the present invention is to provide a kind of high temperature resistant, plastic cement that mechanical property is good with Masterbatch and preparation method thereof.
For achieving the above object, a kind of plastic cement Masterbatch provided by the invention comprises the following component of calculating according to the mass fraction:
(a) ethylene methyl acrylate copolymer 45-65 part;
(b) inorganic or pigment dyestuff 20-50 part;
(c) silane coupling agent 0.5-1.5 part.
For achieving the above object, the present invention also provides the preparation method of a kind of plastic cement with Masterbatch, comprising:
With the silane coupling agent blend milled processed of the mineral dye of 20-50 part or pigment dyestuff and 0.5-1.5 part 8-12 minute;
The ethylene methyl acrylate copolymer of 45-65 part added in the blend after the above-mentioned grinding carried out again blend 7-10 minute; And
Obtain this plastic cement Masterbatch by the twin screw extruder extruding pelletization.
Plastic cement provided by the invention uses the base-material of high performance ethylene methyl acrylate copolymer as Masterbatch with Masterbatch and preparation method thereof, and add mineral dye or pigment dyestuff and a spot of silane coupling agent co-blended is extruded, granulation, the Masterbatch that obtains has good temperature resistance energy and mechanical property, and can improve the flowability of product.
[embodiment]
Plastic cement of the present invention comprises the following component of calculating according to the mass fraction with the better embodiment of Masterbatch:
(a) ethylene methyl acrylate copolymer 45-65 part;
(b) inorganic or pigment dyestuff 20-50 part;
(c) silane coupling agent 0.5-1.5 part;
(d) lubricant 0.5-2 part.
Wherein, plastic cement of the present invention uses ethylene methyl acrylate (Ethylene-Methyl Acrylate with Masterbatch, EMA) multipolymer is as the base-material of Masterbatch, the thermotolerance of this EMA multipolymer is more than 300 ℃, be difficult for decomposing, when formed product, also can improve the flowability of product, have outstanding snappiness and elasticity, therefore can be used for promoting the resistance to elevated temperatures and the mechanical property of material.
In the present embodiment, the Rutile type Titanium Dioxide in this mineral dye is used to make the white mother; This pigment dyestuff is a high-carbon black pigment, is used to make black masterbatch, and in other embodiments, this mineral dye and pigment dyestuff also can be other pigment, are used to make the Masterbatch of other colors.This silane coupling agent is an aminopropyl triethoxysilane, is used to improve the compatibility of pigment and EMA multipolymer.This lubricant is an ethylene bis stearamide, is used for pigment is played the lubricated effect of dispersion, makes pigment uniform distribution in blend.
Below in conjunction with specific embodiment plastic cement of the present invention is elaborated with Masterbatch and preparation method thereof.
