3D printing high-strength artificial stone pattern die and preparation method thereof

Abstract

The invention belongs to the technical field of artificial stone pattern dies, and specifically relates to a 3D printing high-strength artificial stone pattern die and a preparation method thereof. The 3D printing high-strength artificial stone pattern die is prepared through stainless steel and is provided with thick textures and thin textures, wherein the thick textures are 5-400mm in thicknessand 5-30mm in height; the thin textures are 0.5-5mm in wide and 5-30mm in height. The preparation method comprises the steps of scanning and inputting a natural stone picture or drawing an artificialstone three-dimensional model; jetting stainless powder to manufacture the die through a 3D printer based on the natural stone picture or the artificial stone three-dimensional model; and then processing the die by laser melting, annealing, grinding and polishing. According to the die prepared by the method, the thin textures are extremely hard to break and bend; the washing costs only 10-20min; the abrasion is greatly prevented; the service life is long; the weight is light; various complex textures can be prepared; and the comprehensive use cost is low.

Description

technical field [0001] The invention belongs to the technical field of artificial marble pattern molds, in particular to a 3D printing high-strength artificial stone pattern mold and a preparation method thereof. Background technique [0002] Artificial quartz stone is a new type of stone material that is made of quartz sand powder as the main filler, unsaturated polyester resin as the binder, and is formed by high-pressure compression under vacuum and set at medium temperature. It is a wear-resistant, high-hardness, non-toxic Radioactive pollution, reusable environmental protection, green new building materials and decorative materials. However, the usual quartz stone is a granular plate or a simple short-grained plate. Because there is no rich natural texture and color of marble, the grade of artificial quartz stone cannot be greatly improved. At present, there are pattern plates imitating natural marble at home and abroad, but the color is relatively dull and the texture...

AI Technical Summary

Problems solved by technology

Although this method effectively solves the monotony of patterns, our company has started to use this method to produce marble-like quartz stones since 2013. After nearly five years of practical production experience, we found that this method has the following disadvantages: First, not strong enough

Due to the large size of artificial stone, with a length and width of 1.65*3.2 meters, the mold strength of this plastic material is not strong enough, especially in places with fine lines, the width is only 0.5-5mm, and it is easy to distort, deform or even break

Second, it is difficult to clean

This kind of plastic mold is easy to stick to resin, making it difficult to clean, and the cleaning time is as long as 1-3 hours

Third, short life

This plastic mold is frequently exposed to resin and peroxide, and it can no longer be used for 1-2 months. It needs to be replaced with a new mold, resulting in extremely high mold replacement and production costs.
