Polymerization, polymerization time is 3 hours, high temperature polymerization at 100 ° C, polymerization time is 8 hours, after the viscous slurry M completes the polymerization reaction, the pressure holding temperature reaches 27 ° C, and then the autoclave is ...

Embodiment 2

[0050] like Figures 3 to 5 As shown, the present embodiment provides a method for preparing a spar image by using polymethyl methacrylate, comprising the following steps:

[0051]1) Take the mass percentage of 32% methyl methacrylate, 67% polymethyl methacrylate, 0.3% plasticizer, 0.7% coloring agent and stir, and pour the stirred viscous slurry M To the mold, and the pouring thickness is 10 cm, and then carry out the polymerization at a temperature of 10 ° C, after 50 minutes of polymerization and a layer of hard film is formed on the surface, put it into the autoclave, and in the autoclave, perform a low temperature of 40 ° C in turn. Polymerization, polymerization time is 3 hours, medium temperature polymerization at 70 ° C, polymerization time is 3 hours, high temperature polymerization at 100 ° C, polymerization time is 8 hours, after the viscous slurry M completes the polymerization reaction, the pressure holding temperature reaches 20 ° C, and then Only open the autoc...

Embodiment 3

[0059] The present embodiment provides a method for preparing a spar image using polymethyl methacrylate, comprising the following steps:

[0060] 1) Take 35% of methyl methacrylate, 64% of polymethyl methacrylate, 0.4% of plasticizer, 0.3% of coloring agent, 0.3% of benzoyl peroxide by mass and stir, The stirred viscous slurry M is poured into the mold, and the pouring thickness is 25 cm, and then the polymerization is carried out at a temperature of 20 ° C. In the autoclave, low-temperature polymerization at 50° C. was carried out in turn, the polymerization time was 5 hours, and the medium-temperature polymerization at 89° C. was carried out. The polymerization time was 4 hours and the high-temperature polymerization at 110° C. The polymerization time was 9 hours. After the pressure holding temperature reaches 10℃, the autoclave is opened, and the spar A is taken out and polished; the pressure parameter of the autoclave is 0.8MPa;

[0061] 2) The image is printed on the UV...

Abstract

The invention discloses a method for preparing a spar image by using polymethyl methacrylate, relates to the field of plastic high polymer materials, and solves the problems of low color trueness, poor image detail reduction degree and no aesthetic property of a finished product caused by the existing method for making an image into a transparent product. Comprising the following steps: mixing methyl methacrylate and polymethyl methacrylate to obtain viscous slurry M, then putting the viscous slurry M into an autoclave for polymerization to obtain spar A, printing an image on the spar A, casting the viscous slurry M again, and putting the viscous slurry M into the autoclave for polymerization to obtain a spar finished product B; the spar finished product B formed by heating and polymerizing methyl methacrylate and polymethyl methacrylate has better high transparency and is easy to dye, so that the manufactured spar is high in image color trueness and good in image reduction degree, and when the spar is polymerized in the autoclave, the spar A and the viscous slurry M can be fused together, so that a seamless effect can be achieved.

Description

technical field [0001] The invention relates to the field of plastic polymer materials, and more particularly to the technical field of a method for preparing a spar image by using polymethyl methacrylate. Background technique [0002] At present, there are two ways to make images into transparent material products. The first is laser engraving technology, which is to focus a pulsed laser inside the transparent product to generate micron-sized vaporization burst points, which are then controlled by a calculator. There is a burst point, so an image can be formed inside the transparent product, and there are no seams on the edge, but the production cost is huge. Secondly, the laser engraving image is composed of a group of bubble particles, which cannot restore the details of the image, the color authenticity is not high, and it cannot make colored images. [0003] Another method is to make the image into a transparent product. After selecting transparent products such as gla...
