Description

A kind of PC plastic material and preparation method

technical field

The invention relates to a PC plastic material, in particular to a PC plastic material capable of radium-carving fonts or patterns of different colors on the surface of a product and a preparation method thereof.

Background technique

When the original products are used to print characters or patterns on some products, they are used for various logos by silk screen printing or labeling. Although the cost of silk screen printing products is low, but the ink sticks to it, the wear resistance is not good. And the printed fonts will have burrs, which will affect the appearance, and as long as there are impurities or dust on the surface of the product, the product will become an inferior product with a high rate of defective production.

Contents of the invention

The purpose of the present invention is to: aim at the above-mentioned defects of the prior art, provide a kind of PC plastic material and preparation method; Adopt the plastic product that this new type of plastic material produces, can directly burn part of material by laser light energy on the surface, obviously Produce the graphics and text to be etched. The clarity of the product can also be used to laser engrave the QR code on the product and scan it. The products produced by laser engraving can completely replace the silk screen printing process with high precision, and the designed fonts can be exactly the same, very beautiful, the products appear high-end and exquisite, and the production defect rate is low, thereby improving production benefit. In the past, ink screen printing or label glue pasting involved the concept of environmental protection, and the plastic products produced by this new type of plastic material have better environmental protection characteristics.

A PC plastic material is provided, which is made by mixing the following raw materials according to the mass ratio:

Polycarbonate 80-93; MBS or silicon-based toughening agent 1-3; high-temperature-resistant special high-efficiency flame retardant additive or flame retardant mixed with KSS and PTFE 0.1-0.4; high-pigment carbon black or titanium dioxide 1-4.

A PC plastic material is provided, which is made by mixing the following raw materials according to the mass ratio:

Polycarbonate 80; MBS or silicon-based toughening agent 3; high-temperature-resistant special high-efficiency flame retardant additive or flame retardant mixed with KSS and PTFE 0.4; high-pigment carbon black or titanium dioxide 4.

A PC plastic material is provided, which is made by mixing the following raw materials according to the mass ratio:

Polycarbonate 93; MBS or silicon-based toughening agent 2; high-temperature-resistant special high-efficiency flame retardant additive or flame retardant mixed with KSS and PTFE 0.2; high-pigment carbon black or titanium dioxide 3.

A method for preparing the above-mentioned PC plastic material is provided; comprising the steps of:

One: mix:

1) First pour polycarbonate and toughener and stir for 2-3 minutes to mix well

2) Pour in high-pigment carbon black or titanium dioxide pink powder, and stir for another 2-3 minutes

3) Pour in the flame retardant and set the stirring time for 18-20 minutes to ensure uniformity;

2. Production of pellets:

1) Set the temperature of the machine, place the sand net, check whether the temperature reaches the set value, pour it into the hopper of the granulator, and start production after checking;

2.) During the manufacturing process, the physical properties of the beer board are inspected;

3.) Stir the finished particles for 30-40 minutes, weigh and pack after stirring evenly.

The products produced by the present invention can engrave any font or pattern on the surface with high precision and are very beautiful. However, traditional silk screen printing uses ink to stick on the product, which has poor wear resistance and prints out fonts. There will be burrs, which will affect the appearance, and as long as there are impurities or dust on the surface of the product, the product will become an inferior product with a high rate of defective production. The plastic products produced by this new type of plastic material can directly burn part of the material through laser light energy on the surface, and show the graphics and characters to be etched. The clarity of the product can also be used to laser engrave the QR code on the product and scan it. The products produced by laser engraving can completely replace the silk screen printing process with high precision, and the designed fonts can be exactly the same, very beautiful, the products appear high-end and exquisite, and the production defect rate is low, thereby improving production benefit. In terms of the unenvironmental concept of ink screen printing or label glue pasting in the past, the plastic products produced by this new type of plastic material are more advanced. At the same time, this new type of plastic black product can be laser engraved into white or golden yellow, which is quite exquisite and beautiful. It can also carve out the QR code graphics for product anti-counterfeiting scanning.
