Problems solved by technology

The company has been committed to the research and development of stone surface treatment technology, and is very familiar with the current situation of stone products in the building materials industry. In the traditional stone surface processing technology, solvent-based synthetic coatings are generally used, not only because of the long curing time, but also the production efficiency is very low. , and because of the serious environmental pollution and high energy consumption caused by solvent volatilization, it does not meet the requirements of environmental protection and energy saving. The company fully understands that the application of surface light curing treatment technology to stone to improve the quality and grade of stone is an inevitable development trend

Embodiment 1

[0030] The steps and process parameters of the photocuring treatment method:

[0031] 1. Clean the surface of the stone so that there is no dust, oil stains, etc. on the surface;

[0032] 2. To dry the surface of the stone, it can be dried naturally, dried or blown dry, so that there is no moisture, moisture, etc. on the surface;

[0033] 3. Glue coating: apply the light-curing glue on the surface of the stone, and scrape the glue twice with a trowel, so that the glue can penetrate into the pits and cracks to form a coating; it can also be applied by a flow coating machine;

[0034] 4. Ultraviolet light curing: Send the glue-coated stone into the ultraviolet light device, using a metal halide ultraviolet lamp light source with a wavelength of 365 nm, and the ultraviolet intensity of the metal halide ultraviolet lamp is 56 watts / cm. The distance between the layer surfaces was 11 cm and the irradiation time was 6 seconds.

Embodiment 2

[0038] The steps and process parameters of the photocuring treatment method:

[0039] Step is the same as embodiment 1; Parameter changes are as follows: adopt metal halide near ultraviolet lamp tube light source, wavelength 335 nanometers, the ultraviolet intensity of ultraviolet lamp tube is 75 watts / centimeter, the distance between near ultraviolet light source and coating surface is 14 centimetres, The irradiation time was 8 seconds.

[0040] The effect of the stone surface after treatment and the performance test results of the cured film:

[0041] The aesthetics of the stone surface is greatly improved by visual inspection, the original pits, cracks and other defects are filled, the brightness reaches above 80 degrees, and the adhesion test results show that more than 90% of the cured film does not fall off.

Embodiment 3

[0043] The steps and process parameters of the photocuring treatment method:

[0044] Step is the same as embodiment 1; Parameter changes are as follows: adopt metal halide near-ultraviolet lamp tube light source, wavelength 385 nanometers, the ultraviolet intensity of metal halide ultraviolet lamp tube is 40 watts / centimeter, the distance between near-ultraviolet light source and coating surface is 10 cm, and the irradiation time was 10 seconds.

[0045] The effect of the stone surface after treatment and the performance test results of the cured film:

[0046] The aesthetics of the stone surface is greatly improved by visual inspection, the original pits, cracks and other defects are filled, the brightness reaches above 80 degrees, and the adhesion test results show that more than 90% of the cured film does not fall off.

Abstract

The present invention is one kind of light curing treatment method for the surface of stone material, and the method has no solvent pollution, raised production efficiency, raised stone material quality, environment protecting effect and low power consumption, and can form film fast. The method includes the following steps: cleaning surface, drying surface, coating light cured glue to the surface of stone material homogeneously to form coating, and light curing to form film via irradiating withnear ultraviolet ray for certain time.

Description

technical field [0001] The invention relates to a processing technology for stone surface treatment, in particular to a stone surface photocuring treatment method. Background technique [0002] Light-curing adhesives have excellent properties of high solid content, no solvent pollution, and rapid curing to form films under ultraviolet light irradiation, and are increasingly widely used in the field of surface treatment technology. The company has been committed to the research and development of stone surface treatment technology, and is very familiar with the current situation of stone products in the building materials industry. In the traditional stone surface processing technology, solvent-based synthetic coatings are generally used, not only because of the long curing time, but also the production efficiency is very low. , and because of the serious environmental pollution and high energy consumption caused by solvent volatilization, it does not meet the requirements of...
