(7) product with moulding uses the laser engraving machine engraving to form pattern or literal, and wherein the power of laser engraving machine can be selected 50W for use, and laser speed can be selected 7Kmm/s for use.
Because of containing following composition and performance in the resin combination of the present invention:
(1) thermal stability difference pigment;
(2) PMMA itself has good foaminess;
(3) divinyl has softening PMMA and is combined into the performance of magnetic white with PMMA;
Therefore, the resin combination pellet that aforesaid method is made has good foaminess, exists thermal stability difference between pigment and resin combination itself and the composite pigment.Under laser is strafed moment high temperature, the position of being strafed is produced be subjected to heat foamable fast, and the strong component of relatively poor component of pigment thermostability and thermostability is separated, thereby produce heterochromaticly, therefore formation has certain relief font or pattern.
Product after the moulding of use said composition is applicable to that laser sculpture forms the literal or the pattern of various lines smooth and continuous; can carve out white writing or pattern as black product; the purple product can be carved out blueness or red literal or pattern; green product can be carved out yellow literal or pattern, and mazarine can be carved out red-purple etc.Compare with the traditional oils impression method, this formation literal or method of patterning have good environmental-protection function, and working efficiency can improve more than 30 times, cost can reduce by 10 times, the precision height can be on concave plane, and particularly formation mark in shelter such as slit or perforate is used for false proof.In addition, the literal of its formation or pattern resistance to abrasion are more than 50 times of mimeograph, and difficult drop-off has performances such as antiacid, alkali, oiliness, are suitable for different areas and complex environment and use.
Preparation method's technology of resin combination of the present invention is simple, and each composition mixes very evenly in the composition grain of formation, guarantees that the lines of the literal carved or pattern are uninterrupted.
Example one
This example forms white text with the black product engraving or pattern is the manufacture method that example illustrates resin combination of the present invention, its preparation method and product.Wherein resin combination carries out proportioning by following mass percent:
Polymethylmethacrylate 75%
Polyethyl methacrylate 24.5%
The black pigment 0.5% of Heat stability is good

(4) particle with step (3) is that raw material is injection molded into telephone outer shell;
(5) telephone outer shell is put into laser engraving machine, with power 50W, laser speed 7Kmm/s carries out laser sculpture, thereby forms the white numeral on telephone outer shell, and also forms white marker and pattern on shell.
The principle that forms white numeral, sign and pattern is: under laser is strafed moment high temperature; the telephone outer shell material of this black is that these resin true qualities add carbon black look pigment and make; it selects for use the thermostability of carbon black look pigment to be higher than this resin combination; the moment of laser high temperature strafe under the condition; resin moment is foamed by heat of solution; the magnetic white of resin own is separated with the carbon black toner, strafes position white composition protrusion generation and have relief white writing or pattern.
Example two
This example carves out yellow literal with the light green product or pattern is the manufacture method that example illustrates resin combination of the present invention, its preparation method and product.Wherein resin combination carries out proportioning by following mass percent:
Polymethylmethacrylate 75%
Poly-n-butyl methacrylate 24.5%
Green composite pigment 0.5%
The green composite pigment of this thermal stability difference, be by titanium blue or green blue and yellow ultramarine by making green at 3: 1, if will make product carve out yellow literal or pattern, then the thermostability of yellow ultramarine is identical with the thermostability of resin own easily molten in the composite pigment, and their thermostability is lower than the blue or green blue pigment of titanium.
The manufacture method of product may further comprise the steps:
(1) drops in the kneader by above-mentioned formulation selection material, under vacuum, high pressure, 200～220 ℃, mediated mixing 40～60 minutes, until plasticating into uniform soft rubber;
