Description
Technical field
The invention belongs to technical field of polymer materials, specifically a kind of bloom cubic texture material and preparation method thereof.
Background technique
Metal-like preference trend is prevailing in the consumer goods currently on the market, especially middle and high-end market, metal-like appearance
50% or more accounting, especially high glaze, the special-effects such as match volume are more pursued by consumer.Gold currently on the market
The realization for belonging to the apparent effect of texture mainly includes lower three kinds: the first uses real sheet metal, and surface carries out wire drawing, erosion
The techniques such as line, anodic oxidation realize decorative effect, though surface effect is good, cannot achieve real while high glaze and cubic texture
It is existing, and price is extremely expensive；Second use overlay film or spraying technology, grain effect is also fine, but exists in production process
The problems such as environmental pollution is big, and material recovery is difficult；The third use is exempted from spray metal texture modified material and is molded, production effect
Rate is high, at low cost and environmentally friendly, but limited and current mark and the apparent forming defect of weld bond, the practical ranges of material contract significantly
It is small.
Therefore a kind of high glaze, low forming defect are developed, while there is the metal-like material pair of cubic texture structure again
There is important value and significance in current consumption market.
Summary of the invention
The purpose of the present invention is to provide a kind of bloom cubic texture materials and preparation method thereof.
The purpose of the present invention can be achieved through the following technical solutions:

Beneficial effects of the present invention:
1, the present invention constitutes space structure using the three-dimensional framework filler of high length-diameter ratio as filling in injection molding process
Skeleton plays orientation guiding role to sheet metal texture toner, and metal-like toner orientation is changed by skeleton filler orientation
Orientation, metal-like toner sheet-like particle orientation present certain rule different orientation, sheet metal texture toner it is reflective
Effect changes, so that macroscopic view seems the metal effect for occurring having match volume, and angle changing is watched, material table
Slight variations can also be occurred by revealing the cubic texture effect come, and have visual angle variation effect.In addition the stereoscopic effect of material
It can be regulated and controled by the number of three-dimensional framework filler.
2, in forming process, metal-like toner can generate common metal texture material in injection molding turbulent flow or welding
Inconsistence problems are orientated, causes moulding surface flow marks or weld bond serious, largely effects on product appearance aesthetic effect, this hair
The three-dimensional framework filler of bright middle use play the guiding role to the orientation of metal-like toner, can weaken significantly and take in this case
To inconsistence problems, the effect of reduction forming defect is played.
3, the addition of three-dimensional framework filler of the present invention reduces the glossiness of material, but by improving Shooting Technique, molding
Product still has bloom mirror effect.
4, the hardness of three-dimensional framework filler and metal-like toner of the present invention height higher than the hardness of substrate resin, prepared
Light cubic texture material hardness also correspondinglys increase, and the scratch resistance of material greatly improves.
Metal-like material stereoscopic effect prepared by the present invention is significant, and has angle change effect, material hardness highly resistance
It scratching, forming defect is few, and it is versatile with existing modified device, it is suitable for mass production.
