Problems solved by technology

However, when the plastic parts made of these raw materials in the prior art form characters or patterns on the surface, generally only ink screen printing method can be used. The mimeograph method, which has not been changed for many years, is complicated to operate, the work efficiency is too low, the cost is too high, and it causes environmental pollution. , the product is not environmentally friendly
Moreover, this traditional mimeograph method cannot work on irregular platforms, especially when forming characters or patterns in hidden places such as slits or openings.
In addition, the characters or patterns formed by the mimeograph method do not have acid, alkali, oil resistance, poor wear resistance, and are easy to fall off.
Due to the limitation of existing raw materials, the molded plastic products cannot be used for laser engraving to form continuous and smooth characters or patterns

example 1

[0071] This example illustrates the resin composition of the present invention, its preparation method and the manufacturing method of the product by taking a black product engraved to form white characters or patterns as an example. Wherein the resin composition is proportioned according to the following mass percentages:

[0072] Powdered PMMA resin 75%

[0073] Butadiene latex 24.5%

[0074] Black pigment with good thermal stability 0.5%

[0075] The manufacturing method of the product includes the following steps:

[0076] (1) Select the materials according to the above formula and put them into the kneader, knead and knead for 40-60 minutes under vacuum, high pressure, and 200-220°C until a uniform soft rubber is masticated;

[0077] (2) Plasticize the kneaded soft glue with a double-roll mill under the heating condition of 180-200°C, and press the soft glue into a sheet;

[0078] (3) cooling the flaky rubber block, and pulverizing to form fine flaky particles;

example 2

[0083] This example illustrates the resin composition, its preparation method and product manufacturing method of the present invention by taking a light green product engraved with yellow characters or patterns as an example. Wherein the resin composition is proportioned according to the following mass percentages:

[0084] Powdered PMMA resin 75%

[0085] Butadiene latex 24.5%

[0086] Green Composite Pigment 0.5%

[0087] The green composite pigment with this difference in thermal stability is made of titanium blue and yellow pigments at a ratio of 3:1 to make green. If the product is to be engraved with yellow text or patterns, the thermal stability of the yellow pigment in the composite pigment is different from that of the resin itself. The thermal stability is the same as soluble, and their thermal stability is lower than that of titanium blue pigments.

[0088] The manufacturing method of the product includes the following steps:

[0089] (1) Select the materials a...

Abstract

The invention relates the resin composition and the plastic rubber product and preparing method, comprising 25%-90% base resin, 5-70% substance with butadienyl and 0.1-5% heat stability difference color. The base resin comprises polymethyl methacryate, polyethyl methacrylate, or poly-n-butyl methacrylate. The resin is used to carve word or pattern with laser ray, and the word has the advantages of environmental protection, high efficiency and low cost.

Description

technical field [0001] The invention relates to a resin composition for preparing plastic parts of products such as cards, telephones, computer keyboards, fax machines and a method for preparing the plastic parts. The resin composition is suitable for laser engraving. Background technique [0002] The plastic parts of products such as cards, telephones, computer keyboards, and fax machines are generally injection-molded with resin materials such as ABS and HIPS (high-impact polystyrene resin). However, when the plastic parts made of these raw materials in the prior art form characters or patterns on the surface, generally only ink screen printing method can be used. The mimeograph method, which has not been changed for many years, is complicated to operate, the work efficiency is too low, the cost is too high, and it causes environmental pollution. , The product is not environmentally friendly. Moreover, this traditional mimeograph method cannot work on irregular platforms,...
