Abstract
The invention relates to a static-free low-wrap cold-resistant heat-resistant low-cost polypropylene composite material. The material is prepared from the following components in percentage by weight: 30-60 percent of polypropylene, 8-18 percent of conductive material, 20-60 percent of talcum powder and glass microballoons, 0.3-1.5 percent of coupler, 5-15 percent of tougher, a suitable amount of disperser and others. The preparation method of the composite material comprises the following steps of: premixing and treating the conductive material, the talcum powder, the glass microballoons, the coupler and the disperser in a high-speed mixer for 8-10 min; then, adding polypropylene and the toughener and mix at a high speed for 8-10 min; storing the mixture in a charging barrel of a pelletizer; and mixing, extruding and pelletizing with a double-screw extruder. Products which are made from the material by adopting a plastic injection technology can be continuously used at 20 DEG C below zero to 120 DEG C and can be used as semiconductors and static-free production technology equipment and products in the petrochemical industry, military, the aerospace and aviation industry and the IT (Information Technology) industry as well as static-free devices and tools for production and living.
Description
One, affiliated technical field
The present invention relates to low heat-resisting cold-resistant low-cost composite plastic of polypropylene material of warpage of a kind of anti-electrostatic (conduction) and manufacture method, the anti-electrostatic that is particularly useful for using in cold district and high thermal environment overlaps material.
Two, technical background
Because a large amount of uses easily produce and gather the electrostatic insulating polymeric material in the modern life and production, the voltage right and wrong of generation 2KV to 60KV are usually seen.Because a large amount of electrostatic accumulations, the spark that static discharge produces or the effect of static electric field power cause that easily burning and blast take place for easy alkene object and explosion hazard gases, disturb the works better of wireless apparatus, make aircraft become deaf person and blind person; Because electrostatic attraction dust makes the substandard purity of medicine entirely, printing quality is descended.In electronic industry, along with the size of circuit is more and more littler, sensitivity increases thereupon to electrostatic in the production.The static limit of the semi-conductor industry of present 30V, and hard disc magnetic head is subjected to the following electrostatic influence of 3V especially.Along with developing rapidly of China's IT industry and improving constantly of state of the art, macromolecular material, microelectronic device etc. have been widely used in each field and products thereof, the electrostatic problem principle of bringing has thus not only caused great financial loss to enterprise, causes heavy losses also for country, the people's lives and property.The cold-resistant heat-resisting low-cost polypropylene of the low warpage of research and development anti-electrostatic overlaps material, to improve engineering plastics in petrochemical complex, military project, IT (information electronics) industry purposes, guarantee production safety, improving the quality of products is significant.Also will have great effect and the actual meaning of using to China's material and equipment manufacturing industry.Change anti-electrostatic, the antistatic polypropylene plastic material of common use on market at present, its production product distortion big, easily warpage, winter hardiness are poor, at easy softening transform more than 90 ℃, only are applicable to the occasion of southern area and normal temperature, the anti-static product of low accuracy requirement.
Three, summary of the invention
The object of the present invention is to provide and a kind ofly have electrostatic-proof function and have the cold-resistant heat-resisting low-cost polypropylene of low warpage and overlap material and manufacture method thereof.
For achieving the above object, the solution that the present invention takes is: the cold-resistant heat-resisting polypropylene cheaply of the low warpage of a kind of anti-electrostatic overlaps material, the composition proportion of its material is (weight percent), polypropylene 30～60%, electro-conductive material 8～18%, talcum powder, glass microballon 20～60%, coupling agent 0.3～1.5%, toughner 5～15%, dispersion agent are an amount of etc., after each component mixes in high-speed mixer according to a certain percentage, mix the torch extruding pelletization through twin screw extruder, promptly get this matrix material.
The preparation method is as follows for this kind anti-electrostatic polypropylene composite material: the pre-mixing in high-speed mixer of electro-conductive material, talcum powder, glass microballon, coupling agent and dispersion agent was handled 8～10 minutes; added polypropylene and toughner high-speed mixing again 8～10 minutes; this kind compound is stored in the storage hopper of tablets press, manufactures the plastic pellet material with dual-screw pelletizer.
Make anti-electrostatic container and anti-electrostatic production utensil with this kind material, the technical parameter of its making is similar to conventional acrylic plastering Shooting Technique, and with the product that this kind anti-electrostatic matrix material is made, its key technical indexes is as follows:
1, tensile strength: 〉=20MPa
2, flexural strength: 〉=30MPa
3, jagged shock strength: 〉=6.0Kj
4, use temperature :-20～120 ℃
5, shrinking percentage: 0.6～0.9 anti-electrostatic index
6, volume resistance 10
3～10
9Between the preparation
7, static declined the phase entirely: less than 2 seconds
Four, embodiment
Below in conjunction with embodiment the present invention is done last description.

The composition proportion of its material is (weight percent), each component such as polypropylene 30～60%, electro-conductive material 8～18%, talcum powder, glass microballon 20～60%, coupling agent 0.3～1.5%, toughner 5～15%, dispersion agent are an amount of.
Implement 2
The pre-mixing in high-speed mixer of electro-conductive material, talcum powder, glass microballon, coupling agent and dispersion agent was handled 8～10 minutes; added polypropylene and toughner high-speed mixing again 8～10 minutes; this kind compound is stored in the discharge barrel of tablets press, is prepared into the plastic pellet material with dual-screw pelletizer.
