Abstract
The invention provides a toughened nylon compound which comprises the components by weight percent: 56-68% of nylon 6, 12-24% of methyl methacrylate-butadiene-styrene graft polymer, 1-5% of phosphite antioxidant, 3-12% of grafted polyethylene and 0.1-3% of polytetrafluoroethylene micro powder. The toughened nylon compound greatly improves the impact strength of nylon, reduces the cost and effectively reduces the water absorption of the nylon.
Description
Technical field
The present invention relates to the nylon field, particularly relate to a kind of toughened nylon compound.
Background technology
Nylon (polymeric amide) has high strength, good mechanical property, physics, mechanical property, electrical property, wear-resisting, the advantages such as oil resistant and chemical-resistant resistance are high such as tensile strength, shock resistance is good, and chemical-resistant resistance and oil-proofness are outstanding, are most widely used kinds in the five large general engineering plastic.Nylon product is widely used in automobile making, electronic apparatus, mechanical means, the fields such as aerospace.The shortcomings such as but most of nylon product all exists low temperature and the dry state impact property is poor, and notched Izod impact strength is low, and water-intake rate is large, thereby limited its application in many aspects.Therefore, occurred on the market many nylon being carried out the nylon product of toughening modifying, to improve the toughness of nylon material.
But therefore the problem such as have preparation tenacity increased nylon complex process in the prior art, notched Izod impact strength is low, cost is higher has been subject to people's broad research.
Summary of the invention
The object of the present invention is to provide a kind of lower-cost toughened nylon compound.
In order to realize purpose of the present invention, a kind of toughened nylon compound provided by the invention is comprised of each component of following weight percent:
Nylon 6 56 ~ 68%;
MBS graftomer 12 ~ 24%;
Phosphite kind antioxidant 1 ~ 5%;
Grafted polyethylene 3 ~ 12%;
Ptfe micropowder 0.1 ~ 3%.
In the preferred embodiment of the invention, a kind of toughened nylon compound is comprised of each component of following weight percent:
Nylon 6 56%;
MBS graftomer 24%;
Phosphite kind antioxidant 5%;
Grafted polyethylene 12%;
Ptfe micropowder 3%.
In the preferred embodiment of the invention, a kind of toughened nylon compound is comprised of each component of following weight percent:
Nylon 6 63%;
MBS graftomer 21%;
Phosphite kind antioxidant 5%;
Grafted polyethylene 9%;
Ptfe micropowder 2%.
Beneficial effect of the present invention is: above-mentioned toughened nylon compound, can greatly improve the shock strength of nylon, and reduce cost, also can effectively reduce the water-intake rate of nylon simultaneously.
Embodiment
Below in conjunction with embodiment, the invention will be further elaborated.
Embodiment 1
A kind of toughened nylon compound is comprised of each component of following weight percent:
Nylon 6 68%;
MBS graftomer 12%;
Phosphite kind antioxidant 5%;

The preparation method of above-mentioned toughened nylon compound, its preparation process is:
1, nylon 6 was put into dehumidifying heat pump, 110 ℃ temperature inner drying dehumidifying 8 hours.
2, fully mixing is for subsequent use after 2 minutes put into together high speed mixer through nylon 6, MBS graftomer, phosphite kind antioxidant, grafted polyethylene, ptfe micropowder behind the desiccant dehumidification.
3, the mixture in above-mentioned 2 is put into twin screw extruder, extrude toughened nylon compound by twin screw extruder.
4, then toughened nylon compound forms the nylon composite particle by the dicing machine blank by tie rod after the moulding of cooling trough water-cooled, finishes the preparation of toughened nylon compound.
Utilize the made product of preparation method of above-mentioned toughened nylon compound on the use field, greatly to increase its use range, be widely used in the fields such as automobile making, electronic apparatus, mechanical means, aerospace such as this nylon product.
Embodiment 2
A kind of toughened nylon compound is comprised of each component of following weight percent:
Nylon 6 56%;
MBS graftomer 24%;
Phosphite kind antioxidant 5%;
Grafted polyethylene 12%;
Ptfe micropowder 3%.
Embodiment 3
A kind of toughened nylon compound is comprised of each component of following weight percent:
Nylon 6 63%;
MBS graftomer 21%;
Phosphite kind antioxidant 5%;
Grafted polyethylene 9%;
Ptfe micropowder 2%.
Above-mentioned toughened nylon compound can improve the shock strength of nylon greatly, reduces cost, also can effectively reduce the water-intake rate of nylon simultaneously.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
