Description
Technical field
The present invention relates to a kind of plastics, particularly relate to a kind of composite mobile phone shell material.
Background technology
Early stage mobile phone material mostly is generic engineering plastics, appearance usually without modification, just simple anti-slip veins or spray paint.Although very practical, the psychology that aesthetic feeling is advocated in consumption cannot be met.In mobile phone below, many mobile phones have employed magnificent material to decorate the outward appearance of mobile phone.Wherein, piano baking vanish receives popular welcome.Piano lacquer technique, be the one of baking finish process, operation is very complicated, and the piano baking vanish of mechanization still very fast.Some cell phone manufacturer have employed piano lacquer technique to manufacture, and some then sprays paint with common polyurethane paint, technique and durability degree aspect far short of what is expected.Piano baking finish process gives top grade, magnificent aesthetic feeling in appearance, highlights the texture of mobile phone, also brings good feel.Current this technology is very ripe, but service time longer there will be comes off or depainting phenomenon, and becoming easily infected by fingerprint, to affect mobile phone attractive in appearance, and wear-resistant aspect need to improve.So, select actually or abandon also seeing the attitude of consumer oneself.
Summary of the invention
The object of the present invention is to provide a kind of composite mobile phone shell material, there is wear-resisting, oil resistant, transparent, the features such as good springiness.
Technical scheme of the present invention is: a kind of composite mobile phone shell material, described composite mobile phone shell material comprises the TPUE rubber of the superiors, macromolecule transparent material and the undermost PET in intermediate layer combine, described TPUE rubber includes polyester-type and polyether-type, described TPUE rubber accounts for the 32%-33% of composite mobile phone shell all materials component, described macromolecule transparent material accounts for the 33%-34% of composite mobile phone shell all materials component, described PET accounts for the 32%-36% of composite mobile phone shell all materials component.
In a preferred embodiment of the present invention, described PET comprises PET PET and polybutylene terephthalate PBT.
In a preferred embodiment of the present invention, described TPUE rubber accounts for 32% of composite mobile phone shell all materials component, described macromolecule transparent material accounts for 33% of composite mobile phone shell all materials component, and described PET accounts for 35% of composite mobile phone shell all materials component.
A kind of composite mobile phone shell material of the present invention, has wear-resisting, oil resistant, transparent, the features such as good springiness.
Detailed description of the invention
Be described in detail below in conjunction with to preferred embodiment of the present invention, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
In one embodiment, described composite mobile phone shell material comprises the TPUE rubber of the superiors, the macromolecule transparent material in intermediate layer and undermost PET and combines, described TPUE rubber includes polyester-type and polyether-type, described TPUE rubber accounts for the 32%-33% of composite mobile phone shell all materials component, described macromolecule transparent material accounts for the 33%-34% of composite mobile phone shell all materials component, and described PET accounts for the 32%-36% of composite mobile phone shell all materials component.
Further illustrate, described PET comprises PET PET and polybutylene terephthalate PBT, described TPUE rubber accounts for 32% of composite mobile phone shell all materials component, described macromolecule transparent material accounts for 33% of composite mobile phone shell all materials component, and described PET accounts for 35% of composite mobile phone shell all materials component.
Further illustrate, TPUE rubber is a kind of material between rubber and plastics as elastomer, and this finds out from its rigidity, and the rigidity of TPUE rubber can be measured by elastic modelling quantity.The elastic modelling quantity of rubber is usually at 1-10Mpa, and TPUE rubber is at 10-1000Mpa, and plastics are at 1000-10000Mpa.The hardness range of TPUE rubber is quite wide, has high resiliency from ShoreA60-ShoreD80 in whole hardness range; TPUE rubber in very wide temperature range-40-120 DEG C, has flexibility, and does not need plasticizer; TPUE rubber has good resistivity to oils (mineral oil, animal and plant fat and lubricating oil) and many solvents; TPUE rubber also has good resistance to weather, extremely excellent resistance to high-energy ray performance.Well-known wearability, tear resistance, it is all excellent for bending and disturbing intensity; Hot strength is high, and percentage elongation is large, and the low grade of long compressive permanent set is all the remarkable advantage of TPUE rubber.
TPUE rubber performance: mechanical property: the mechanical property of TPUE rubber elastomer mainly comprises: hardness, hot strength, compression performance, tearing strength, resilience and anti-wear performance, resistance to immunity in the wrong etc., and the mechanical property of TPUE caoutchouc elasticity plastics, except these performances, also have higher shear intensity and ballistic work etc.
Further illustrating, PET molecular structure high degree of symmetry, there is certain crystalline orientation ability, so there is higher film forming and become second nature.PET has good optical property and weatherability, and amorphous PET has good optical transparence.PET has excellent abrasion performance frictional property and dimensional stability and electrical insulating property in addition.The bottle that PET makes has that intensity is large, the transparency is good, nontoxic, impermeable, quality is light, high thus the receiving of production efficiency is applied widely.PBT and PET molecular chain structure is similar, and most of character is also the same, and just molecular backbone becomes four by two methylene, so molecule is submissiveer, processing characteristics is more excellent.
PET is the polymer of milky or light yellow highly crystalline, surface smoothing and glossy.Resistance to creep, fatigue resistance, rub resistance are good, wear away little and hardness is high, have toughness maximum in thermoplastic; Electrical insulation capability is good, and temperature influence is little, but corona resistance is poor.Nontoxic, against weather, chemical proof good stability, hygroscopicity is high, and the drying before shaping is necessary.Weak acid resistant and organic solvent, but thermo-labile water soaking are not alkaline-resisting.The vitrification point of PET resin is higher, and crystallization rate is slow, and moulding cyclc is long, and molding cycle is long, and molding shrinkage is large, poor dimensional stability, and the shaping of crystallization is fragility, and heat resistance is low.The invention provides a kind of composite mobile phone shell material, there is wear-resisting, oil resistant, transparent, the features such as good springiness.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
