Description
Technical field
The present invention relates to field of material technology, it is more particularly related to a kind of counter body and its manufacturer
Method.
Background technology
The shell of computer or electronic calculator can protect inner body, therefore be contemplated that shell during manufacture shell
Certain mechanical strength is needed to have to play resistance to compression shockproof properties.
With the development of technology, the shell of electronic computer is endowed increasing function, such as radiation proof, anticorrosive corruption
Erosion, antistatic and radiating etc..The shell of existing electronic computer or electronic product is mostly plastics, and is mostly using single
Kind or a small amount of several resins suppress obtained plastics, such as the hair of Application No. 2014108564356 and 2015107746775
Bright patent, although the plastics that single resin is suppressed to obtain prepare simple low cost, but can not overcome the shortcomings that single resin,
Therefore it is many to suppress obtained plastics shortcoming.
Such as polyphenylene oxide：Combination property is good, and electrical insulating property is good, and water suction is small, but has stress cracking tendency.There is prominent electricity absolutely
Edge and excellent water resistance, there are preferable wearability and electrical property, good stability of the dimension.Its dielectric properties occupies the first place of plastics.
There is higher heat resistance, anti-flammability is good, has from breath property, has medium combustibility after being mixed with HIPS.It is light, it is nontoxic available
In food and medicine industry.Light resistance is poor, and use can change colour in the sun for a long time.With rigidity is big, heat resistance is high, it is fire retardant,
The advantages that intensity is excellent compared with high electrical performance.Gathering this ether also has the advantages that wear-resisting, nontoxic, anti-pollution.Major defect is melting stream
Dynamic property is poor, and machine-shaping is difficult.
Polypropylene：Relative density is small, only 0.89-0.91, is one of kind most light in plastics.Good mechanical property
Can, in addition to impact resistance, other mechanical properties are better than polyethylene, and moulding processability is good.With higher heat resistance, continuously
Temperature in use is up to 110-120 DEG C.Quality is pure, non-toxic.Electrical insulating property is good.Shortcoming：Product cold resistance is poor, and low-temperature impact is strong
Spend low.Product in use easy light, heat and oxygen effect and aging.Coloring is bad.Easy firing.Toughness is bad, electrostatic degree
Height, dyeability, printing and adhesion are poor.
Polyvinyl chloride：Maximum feature is fire-retardant, is widely used in flame retardant application.But polyvinyl chloride in combustion can
Discharge hydrogen chloride and other toxic gases, such as dioxin.It is cheap, be widely used, Corvic for white or
Buff powder.Different additives can be added according to different purposes, igelite can present different physical
Energy and mechanical property.RPVC has preferable tension, bending resistance, resistance to compression and impact resistance, can individually be used as structural wood
Material.Flexibility, elongation at break, the cold resistance of soft PVC can increase, but fragility, hardness, tensile strength can reduce.It is poly-
Vinyl chloride has preferable electrical insulation properties, can make low frequency insulating materials, and its chemical stability might as well.The thermostabilization of polyvinyl chloride
Property is poor, and long-time heating can cause to decompose.
Polyethylene：In the presence of air, sunlight and oxygen, it may occur that aging, change colour, be cracked, becoming fragile or efflorescence, losing it
Mechanical property.At a temperature of processing and forming, it also can decline its melt degree of killing because of oxidation, discoloration occurs, striped occurs,
So in processing and forming and attention is should give during using process or selection.Just because of polyethylene possesses as above speciality, it is easily worked
Shaping, therefore the regeneration recovery of polyethylene has very far-reaching value.
ABS resin：Weatherability it is poor, be also easy to produce degraded under the action of uv light；After outdoor half a year, under impact strength
Half drops.ABS plastic tubing, sulfuric acid corrosion resistant, does not meet sulfuric acid with regard to comminuted rupture.
Makrolon：Weak acid resistant, resistance to weak base, resistance to neutral oil.Not ultraviolet resistance, intolerant to highly basic.Main performance defect is resistance to
Hydrolytic stability is not high enough, and to notch sensitive, resistance to organic chemistry moral character, resistance to scratch is poor, is exposed to meeting in ultraviolet for a long time
Jaundice.As other resins, easily corroded by some organic solvents.
Sodium metasilicate：Cohesive force is strong, intensity is higher, acid resistance, heat-resist, alkali resistance and poor water resistance
Every kind of resin has its feature and shortcoming, if can mix various kinds of resin, complementary win-win, suppresses obtained modeling
Material advantage can be protruded more, and shortcoming can cut down or even eliminate, and also be more suitable for being used as electronic product casing.
The casing plastic sense of traditional computer or electronic product is dense simultaneously, and feel is bad, in light weight, gives people bad
Usage experience.
Therefore a kind of counter body for including various kinds of resin is designed, producing the counter body of superior performance turns into one
The problem of individual urgent need to resolve.
