Abstract
The invention relates to a casing material of a hospital queue number machine. The material has high strength and good lubricating property, and the scratch resistance of the material is effectively improved. Compared with the traditional casing material of the hospital queue number machine, the casing material provided by the invention has good tenacity and is not likely to cause coating shed.
Description
Technical field
The invention relates to a kind of hospital Zero queuing machine sheating material, the scratch resistance ability that it has higher intensity and strengthens, and have certain toughness.
Background technology
Because hospital's Zero queuing machine rate of utilization is very high, its outermost material is generally polythene material, but the intensity of polythene material is lower, be easy to be worn in the process of using, perhaps suffer to scratch and destroy, for example the slight friction of nail just can abrade or scratch its surface easily, influences the outward appearance of Zero queuing machine, therefore often need increase protective layer in position the most easy to wear.And protective layer commonly used is the clinkery epoxy powder coating, and it has higher intensity, hardness, by scratching experiment test; scratch depth is more shallow; can be used as the coating of the scratch resistance ability that improves material, but that the shortcoming of this coating is toughness is relatively poor, causes coming off of coating after being scratched easily.
The research report in Europe shows, by add the lubricant polysiloxane or with the aliphatic amide modification, can improve scratch resistance and the scratch property of thermoplastic olefin, but doing the shortcoming of bringing like this is, the mechanical property of material is not high, and surface gloss does not reach requirement.
In addition, patent 99804334 discloses a kind of composition with improved scratch resistance and scratch performance, it comprises: (1) a kind of graft copolymer, it comprises the amphoteric polymeric material main chain, graft polymerization has at least a vinyl monomer that can carry out radical polymerization on this main chain, (2) a kind of additive, it is selected from, gross weight by composition, (a) at least a low-molecular ethylene polymers of about 0.5%-10% or its functionalized derivative and (b) at least a low-molecular ethylene polymers (a) and the (ii) mixture of about 0.5-10% inorganic microspheres of (i) about 0.5%-10%.Said composition also randomly contains the functionalized amphoteric polymeric material of compatilizer such as unsaturated carboxylic acid.Said composition optionally contains one or more rubber components of 2-30% of having an appointment, the amphoteric polymeric material of about 15-50% wide molecular weight distribution or both mixtures.
But the intensity of said composition does not reach the requirement as sheating material, and therefore, desirable hospital's Zero queuing machine sheating material need namely have higher intensity, has good toughness and scratch resistance ability again.
Summary of the invention
The object of the present invention is to provide a kind of hospital Zero queuing machine sheating material, have higher intensity and good toughness, excellent lubricating property can improve the scratch resistance performance of material effectively.
Technical solution of the present invention is as follows: a kind of hospital Zero queuing machine sheating material, comprise 100 parts of polyether-ether-ketones or tetrafluoroethylene, 5-8 part carbon fiber or glass fibre, 3-5 part graphite and/or molybdenumdisulphide, 2-5 part titanium dioxide, 0.1-0.4 part methacrylic acid or methacrylic ester, 0.3-0.5 part initiator, 1.5-2 part softening agent, said components is in twin screw extruder, at 280-360 ℃ of following extruding pelletization.
Described initiator is a kind of in dicumyl peroxide, di-t-butyl peroxide or the dibenzoyl peroxide.
Said components can also add 0-1 part anti-aging agent.
Can also add 0-3 part oxidation inhibitor.
The beneficial effect of sheating material of the present invention is:
(1) have higher intensity, and excellent lubricating property, effectively improved hospital's Zero queuing machine sheating material scratch resistance performance, increase the work-ing life of hospital's Zero queuing machine shell;
(2) have good toughness, better with the adhesive property of primer, difficult drop-off;
(3) need not protective coating, cost is lower.
