Abstract
A disclosed polyoxymethylene modification material comprises, in percent by mass, 42-73% of polyoxymethylene, 2-3% of a lubricant, 5-10% of a metal powder, 1-3% of melamine, 1-3% of an inorganic nano-material, 1-3% of an anti-oxidant, 5-15% of a siloxane master batch, 2-4% of a flexibilizer, 5-15% of polyurethane, and 4-8% of a flame retardant additive. The employed formula is scientific, the prepared material possesses good lubricity, toughness, strength, heat conductivity, bearing capability, antiwear property and other advantages, also by adding the melamine composition into polyoxymethylene, the processing process of polyoxymethylene is facilitated to be improved, generation of excitant gases is reduced, and harm to human body is reduced.
Description
Technical field
The present invention relates to a kind of material modified technical field, be specifically related to a kind of polyoxymethylene modified material.
Background technology
Polyoxymethylene (Polyformaldehyde, write a Chinese character in simplified form POM) be that one does not have side chain, high-density, the thermoplastic engineering plastic of high crystallization, has excellent mechanical property, outstanding self-lubricity, wear resistance and chemical proofing, rigidity is large, creep resistant and fatigability good, and mechanics, chemistry and the electrical property that can in wide temperature range, keep it to have, be in engineering plastics closest to one of kind of metal, can be used to replace the nonferrous metal and alloy such as aluminium, zinc goods.Polyoxymethylene can adopt the methods such as injection, blowing, extrusion molding and spiral casting to process, and is widely used in automotive industry, electric, the industry such as household electrical appliance, precision instrument and building materials.With the high speed development of modern plastics industry, global POM product consumption demand increases rapidly, one of a kind of very important engineering plastics having become the world today.
But the impelling strength of polyoxymethylene is low, notch sensitivity is poor, easily the shortcoming such as decomposition significantly limit its application in each field particularly expensive goods field in the course of processing, therefore improves the decomposition of polyoxymethylene in the course of processing and just seems very important.
Summary of the invention
Goal of the invention: the object of the invention is, in order to make up the deficiencies in the prior art, to provide a kind of polyoxymethylene modified material, making polyoxymethylene reduce decomposition in the course of processing as far as possible.
Technical scheme: a kind of polyoxymethylene modified material, comprises following component and mass percentage content:
Polyoxymethylene 42-73%,
Lubricant 2-3%,
Metal powder 5-10%,
Trimeric cyanamide 1-3%,
Inorganic nano material 1-3%,
Oxidation inhibitor 1-3%,
Siloxanes master batch 5-15%,
Toughner 2-4%,
Urethane 5-15%,
Flame-retardant additive 4-8%.
Described polyoxymethylene comprises kematal and homopolymerization polyoxymethylene, and described lubricant comprises tetrafluoroethylene, molybdenumdisulphide and graphite.
Described inorganic nano material comprises nano aluminium oxide, nano silicon oxide, and this inorganic nano material is single powder or mixture.
Described metal powder is one or more in the copper alloy powder of sheet, zinc powder or copper powder.
Beneficial effect: the scientific formulation that the present invention adopts, the material made has the advantages such as good oilness, toughness, intensity, thermal conductivity, supporting capacity and wear resistance, the tripolycyanamide simultaneously added in polyoxymethylene, favourable the polyoxymethylene course of processing to be improved, reduce the generation of irritant gas, reduce the injury to human body.
