Preparation method of nano porcelain-like sand grains

Abstract

The invention discloses a preparation method of nano porcelain-like sand grains. The nano porcelain-like sand grains are prepared from light calcium powder, plant cellulose, negative ion powder, edible gum, food colouring, dicalcium silicate, tricalcium aluminate and pearl powder in proportion. According to the preparation method of nano porcelain-like sand grains provided by the invention, pure natural inorganic powder and plant extract are polymerized and then fired to obtain the product, SGS detection indicates that the nano porcelain-like sand grains have no pollution or radioactivity, donot contain formaldehyde or other harmful substances, the grains are uniform, smooth, clean and free of fine sand, are healthy, environment-friendly, high strength, flame retardant, safe and environment-friendly sand grains, also carry negative ions in themselves, can effectively inhibit the breeding of bacteria, have the advantages of washability, great color variety, flame retardance, smooth surface, high hardness, health and environmental protection, sterilization function in themselves, provide children with a safer, healthier, more environmentally friendly, and also recyclable entertainment environment, and bring better application prospects.

Description

technical field [0001] The invention relates to the technical field of novel inorganic non-metallic materials, in particular to a method for preparing nano-porcelain imitation sand particles. Background technique [0002] The sand used in existing children's playgrounds and families has many potential safety hazards. It is easy to breed bacteria, is flammable, has too many uneven particles, and enters children's eyes, ears and respiratory tracts. It is flammable, It cannot be washed with water, it is easy to breed bacteria, the color is single, the surface is not smooth or even sticks to hands, etc. For this reason, we propose a method for preparing nano-porcelain-like sand. Contents of the invention [0003] The main purpose of the present invention is to provide a method for preparing nano-porcelain-like sand particles, which can effectively solve the problems in the background technology. [0004] In order to achieve the above object, the technical scheme that the pres...
