Abstract
The invention discloses a kind of POM and PTFE micro mist copolymers and preparation method thereof, its each component and its content are：POM：65~90%；PTFE micro mists：10~35%.Its preparation method is：1st, by PTFE micro mists and POM batch mixings.2nd, 100 degree are heated in blending, the heat time is 4 hours.3rd, 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 only use and add few PTFE micro mists, itself and POM copolymer can be made there is high-wearing feature, weatherability, chemical resistance, high temperature resistant, low warpage, lower shrinkage, and be not easy to fission.
Description
Technical field
The present invention relates to high performance plastics technical field of modification, more particularly to a kind of high-wearing feature, weatherability, chemically-resistant
Property, high temperature resistant, low warpage, lower shrinkage, it is not easy POM and PTFE micro mist copolymers for fissioning 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, hardness is low.
Therefore, generally use and the method for other materials copolymerization change its characteristic, such as add TPU to improve its impact resistance
Can, still, the method that is copolymerized in the prior art is complicated, and is required to professional equipment and could carry out, and otherwise can not synthesize；And TPU
Addition need higher, complex manufacturing, cost are high, and copolymerization product is softer, hardness is low, it is difficult to meet 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 micro mists copolymer and
Its preparation method, only with adding few PTFE micro mists, you can make itself and POM copolymer there is high-wearing feature, weatherability is resistance to
Chemically, high temperature resistant, low warpage, lower shrinkage, and be not easy to fission.
To achieve these goals, the technical solution adopted by the present invention is：
The percentage by weight of a kind of POM and PTFE micro mist copolymers, its each component included and each component is respectively：
POM 65 ~ 90%
PTFE micro mists 10 ~ 35%.
Preferable scheme, the percentage by weight of the POM and PTFE micro mists are respectively：POM accounts for 65%, PTFE micro mists and accounted for
35%。
Present invention also offers a kind of POM and PTFE micro mist copolymers preparation method, it comprises the following steps：
S1, by POM and PTFE micro mist batch mixings, be heated to 100 DEG C, the heat time is 4 hours.
S2, the extruded machine of compound after hot melt extruded.
Preferably, POM plastic particle, the feed proportioning of PTFE micro mist plastic grains are：65~90%:10~35%.
It is further preferred that the feed proportioning of POM plastic particle, PTFE micro mist plastic grains is：65%:35%.
By using above technical scheme, a kind of POM and PTFE micro mist copolymers of the present invention and preparation method thereof with it is existing
Technology is compared, and its advantage is：
1st, the present invention uses PTFE micro mists, and PTFE micro mists not only remain the original all premium properties of polytetrafluoroethylene (PTFE), also had
There are many unique performances：Such as without self-coagulation, without electrostatic effect, intermiscibility is good, molecular weight is low, good dispersion, self lubricity
High, coefficient of friction reduces obvious etc..When being copolymerized with POM, only with the few PTFE micro mists of addition, you can have its copolymer
High-wearing feature, weatherability, chemical resistance, high temperature resistant, low warpage, lower shrinkage, and be not easy to fission, overall performance greatly enhances, raw
Production cost is greatly lowered.
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 micro mists copolymer：
Formula one：
Weight percentages of components（%）
POM 80
PTFE micro mists 20
Formula two：
Weight percentages of components（%）
POM 90
PTFE micro mists 10
Formula three：
Weight percentages of components（%）
POM 85
PTFE micro mists 15
Formula four：
Weight percentages of components（%）
POM 65
PTFE micro mists 35
It is formulated more than, its preparation process is：
1st, by POM and PTFE micro mist batch mixings, 100 degrees Celsius are heated to, the heat time is 4 hours.
2nd, the extruded machine of compound after hot melt is extruded.
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.
