Abstract
The invention discloses a kind of POM and PTFE copolymers and preparation method thereof, its each component and its content are：POM：50%；PTFE：50%.Its preparation method is：1st, prepare two firing equipments, a main frame, a subsidiary engine, and be separately heated to 280 ~ 380 DEG C and 165 ~ 195 DEG C；2nd, PTFE plastic grains are added into main frame, POM plastic particle is added into subsidiary engine, and debug the rotating speed and feeding rotating speed of main and auxiliaries, make satisfaction feed proportioning；3rd, subsidiary engine is connected with main frame, the material heat that subsidiary engine discharges to main frame is melted section；4th, the extruded machine of compound after hot melt is extruded.Simple production process of the present invention, low-quality product can be changed over premium quality product, low-value product is converted into high-value product, greatly reduces use cost, and product more high temperature resistant, chemical resistance, sliding can be made, and improve its hardness and thermal change type temperature.
Description
Technical field
The present invention relates to high performance plastics technical field of modification, more particularly to a kind of high temperature resistant for improving product, chemically-resistant
Property, sliding, and POM and the PTFE copolymer of its hardness and thermal change type temperature can be improved and preparation method thereof.
Background technology
POM（Acetal resin）Definition：Polyformaldehyde be it is a kind of without side chain, high density, high crystalline linear polymer,
It is the one kind for belonging to engineering plastics, it is firm also to turn into match by people.It is the engineering plastics with excellent combination property.Have good
Physics, mechanically and chemically performance, especially have excellent crocking resistance.
But POM plastic unlike other engineering plastics can high temperature resistant, and also intolerant to bright and new irradiation, acid resistance
Difference, and impact strength is not high.
Therefore, generally use and the method for other materials copolymerization change its characteristic, still, the method being copolymerized in the prior art
Complexity, and be required to professional equipment and could carry out, otherwise it can not synthesize.Its complex process, cost are high, and the intensity of copolymerization product
It is unable to reach demand.
The content of the invention
In order to solve the problems of the prior art, it is an object of the invention to provide a kind of POM and PTFE copolymers and its system
Preparation Method, it can make product more high temperature resistant, chemical resistance, sliding, and can improve its hardness and thermal change type temperature.
To achieve these goals, the technical solution adopted by the present invention is：
The percentage by weight of a kind of POM and PTFE copolymers, its each component included and each component is respectively：
POM 50%
PTFE 50%。
Present invention also offers a kind of POM and PTFE copolymers preparation method, it comprises the following steps：
S1, prepare two firing equipments, one be main frame, one be subsidiary engine, and main and auxiliaries be separately heated to required temperature
Degree；
S2, PTFE plastic grains are added into main frame, POM plastic particle is added into subsidiary engine, and debug turning for main and auxiliaries
Speed and feeding rotating speed, it is allowed to meet feed proportioning；
S3, subsidiary engine is connected with main frame, the material heat that subsidiary engine discharges to main frame is melted section；
S4, by the extruded comminutor of compound after hot melt.
Preferably, the heating-up temperature of main frame is 280 ~ 380 DEG C in step S1, and the heating-up temperature of subsidiary engine is 165 DEG C ~ 195 DEG C.
It is further preferred that the feed proportioning of POM plastic particle, PTFE plastic grains is：50%： 50%.
Still more preferably, the extruder is single screw extrusion machine or double screw extruder.
By using above technical scheme, a kind of POM of the present invention and PTFE copolymers and preparation method thereof and prior art
Compare, its advantage is：
1st, the present invention can make product more high temperature resistant, chemical resistance, sliding, and can improve its hardness and thermal change type temperature.
2nd, it maintains the original characteristics of cryogenic material POM, while can make original material property and usability scope more
Widen general.
3rd, low-quality product is changed over premium quality product by the present invention, low-value product is converted into high-value product, significantly
Reduce use cost.
4th, simple production process of the present invention, production cost are low.
Embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, with reference to instantiation, to the present invention
It is further described.It should be understood that these descriptions are merely illustrative, and it is not intended to limit the scope of the present invention.In addition,
In illustrating below, the description to known features and technology is eliminated, to avoid unnecessarily obscuring idea of the invention.
A kind of POM of the present invention can use formula as below to prepare with PTFE copolymers：
Formula one：
Weight percentages of components（%）
POM 50
PTFE 50
Formula two：
Weight percentages of components（%）
POM 70
PTFE 30
Formula three：
Weight percentages of components（%）
POM 80
PTFE 20
It is formulated more than, its preparation process is：
1st, prepare two firing equipments, one be main frame, one be subsidiary engine, and main and auxiliaries be separately heated to required temperature
Degree；
2nd, PTFE plastic grains are added into main frame, POM plastic particle are added into subsidiary engine, and debug the rotating speed of main and auxiliaries
And feeding rotating speed, it is allowed to meet above-mentioned feed proportioning；
4th, subsidiary engine is connected with main frame, the material heat that subsidiary engine discharges to main frame is melted section；
5th, by the extruded comminutor of compound after hot melt.
Above-mentioned embodiment is exemplary, is to preferably make skilled artisans appreciate that originally
Patent, it is impossible to be not understood as the limitation for including scope to this patent；As long as times made of spirit according to disclosed in this patent
How with change or modification, the scope that this patent includes is each fallen within.
