Description

A kind of light fixture high light transmittance ratio glass cover body and preparation method thereof
Technical field
The present invention relates to glass making techniques field, be specifically related to a kind of light fixture high transmission rate glass Glass cover body and preparation method thereof.
Background technology
Lucite is commonly called as acrylic, middle a surname's acryl, sub-Gree, is divided into water white transparency, has Color is transparent, pearly-lustre, embossing lucite four kinds.Organic glass products refers to by lucite material Expect artware or the consumer goods made according to its good feature.Because lucite has Preferably the transparency, chemical stability, mechanical property and weatherability, easy dyeing, easily process, The advantages such as attractive appearance, so organic glass products is widely used.
Light is when by any medium between its light transmittance (T), reflectance (R) and absorbance (A) Following relation is there is according to law of conservation of energy:
T+R+A=1
Can significantly draw to make glass just obtain higher light transmittance from above-mentioned energy relationship Light reflection in glass medium, scattering and absorption loss water have to be reduced.And in the life of glass During product, the existence of the internal spherocrystal of vitreous body can cause the scattering of light wave so that glass saturating Luminosity reduces.How to reduce or to stop glass in process of production because crystallisation procedure causes spherocrystal Growth become for an important problem.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of light fixture high light transmittance ratio glass cover Body and preparation method thereof.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of light fixture high light transmittance ratio glass cover body, is made up of the raw material of following weight portion: poly-4- Methyl-1-pentene 14-22 part, SB 10-16 part, styrene-acrylonitrile Copolymer 5-9 part, polynorbornene 4-9 part, methyl methacrylate 2-5 part.
Preferably, it is made up of the raw material of following weight portion: poly(4-methyl-1-pentene) 21 parts, benzene second Alkene-butadiene copolymer 13 parts, SAN 7 parts, polynorbornene 5 parts, Methyl methacrylate 2 parts.
Preparation process is as follows:
1) by common to poly(4-methyl-1-pentene), SB, styrene-acrylonitrile After polymers, polynorbornene, methyl methacrylate mix homogeneously, it is warming up to 260 DEG C and is melted Melt thing A；
2) mold cavity carrying out precooling treatment, mold cavity thickness is 3-6mm, chilling temperature For-10-0 DEG C；
3) after fused mass A temperature stabilization, mold cavity is entered with the pressure injection of 12-14MPa In and pressurize, quickly cool down with 90-130 DEG C/min, obtain part B；
4), after part B being carried out deburring process, to obtain final product.
Preferably, described step 2) in mold cavity thickness be 3mm, chilling temperature is-3 DEG C.
Preferably, described step 3) in injection pressure be 14MPa.
Preferably, described step 3) in rate of cooling be 120 DEG C/min.
The invention provides a kind of light fixture high light transmittance ratio glass cover body and preparation method thereof, it has Benefit effect is: raw material of the present invention is amorphous polymers, has the intrinsic property being difficult to crystallization, Each component Combination is preferable.Additionally, raw mixture is heated to 260 DEG C become note after molten state Enter in the mould of precooling treatment the degree of supercooling that can effectively increase molten mass top layer, prevent The crystallization process on molten mass top layer.Meanwhile, can make by arranging relatively thin die cavity thickness Obtain fused mass core and still remain the highest degree of supercooling, center microcell part can be stoped Crystallization process.The present invention effectively prevents the surface of raw materials melt body and the knot of core Brilliant process, effectively inhibits the growth of spherocrystal, decreases the scattering process of light, enhance light The property passed through.Light fixture high light transmittance ratio glass cover body of the present invention and preparation method thereof is prone to real Existing, it is greatly improved the light transmission of glass cover body, has broad application prospects.
