Problems solved by technology

[0003] Due to some defects of natural colored sand, such as poor weather resistance, color and luster can not meet the decoration requirements, the currently mainly used colored sand is artificial colored sand. defect:
This method still cannot escape the weakness of traditional colored sand, and its application field has certain limitations.

Embodiment 1

[0030] Weigh 10g of quartz sand sieved with 50 mesh, add 40ml of distilled water and stir for 20min, add 1g of SnCl 2 , and 0.3g of 32wt% concentrated hydrochloric acid, add 50ml of distilled water, stir and react for 30min, then take it out and rinse with distilled water, filter, and dry to obtain pretreated quartz sand.

[0031] Weigh 1g glucose, 1gAgNO 3 , 3g diethanolamine, 80ml distilled water to prepare a plating solution, add 10g of pretreated quartz sand, stir and react at room temperature for 30min, then wash with distilled water, filter, and dry at 100°C for 1h to obtain colored sand with silver-plated surface. From figure 1 It can be seen from the figure that the surface of the chemically silver-plated colored sand has a strong metallic feel and has the flashing characteristics of silver alone, which can improve the decorative effect of the colored sand.

Embodiment 2

[0033] Weigh 10g of yellow sand sieved with 50 mesh, add 40ml of distilled water and stir for 20min, add 1g of SnCl 2 , and 0.3g of 32wt% concentrated hydrochloric acid, add 50ml of distilled water, stir and react for 30min, then take it out and rinse with distilled water, filter, and dry to obtain pretreated quartz sand.

[0034] Weigh 1g glucose, 1gAgNO 3 , 3g diethanolamine, 80ml distilled water to prepare a plating solution, add 10g of pretreated quartz sand, stir and react at room temperature for 30min, then wash with distilled water, filter, and dry at 100°C for 1h to obtain colored sand with silver-plated surface. From figure 2 It can be seen from the figure that the surface of the chemically silver-plated colored sand has a strong metallic feel and has the flashing characteristics of silver alone, which can improve the decorative effect of the colored sand.

Abstract

The invention discloses a method for preparing colored sand with metallic silver effect. The chemical plating method is mainly used to plate silver metal on the surface of sand and gravel, which mainly includes the following steps: 1) adding pretreated sand and gravel into a container, Distilled water and glucose are fully stirred; 2) Mix a certain amount of silver nitrate with ammonia water or amine, and stir until there is no precipitation; 3) Add the solution in 2) to 1) and stir for a period of time at room temperature, then dry to obtain silver plating colored sand. The preparation process of the present invention is highly efficient, low in cost, high in quality grade, and imparts a strong metallic feeling to the surface of the sandstone.

Description

technical field [0001] The invention relates to the field of artificial colored sand preparation, in particular to the preparation of colored sand with metallic silver effect. Background technique [0002] Colored sand has bright colors, stable performance, and rich texture. It is widely used in building decoration materials, floors, roads, real stone paint and texture coatings, decorative mortar, roofing, etc., and is also used in handicrafts and artistic creations. [0003] Due to some defects of natural colored sand, such as poor weather resistance, color and luster can not meet the decoration requirements, the currently mainly used colored sand is artificial colored sand. defect: [0004] 1. The preparation process of colored colored sand is simple, the equipment requirements are relatively low, and the cost is low. However, because organic pigments are used as the raw material for the preparation, the prepared colored sand has poor weather resistance and is easy to fal...
