Embodiment 1

[0031] This bio-based soft porcelain contains the following raw materials by mass: 100 parts of composite powder, 50 parts of polyacrylate emulsion, 15 parts of silane coupling agent, 5 parts of polyether polyurethane, 10 parts of polydimethylsiloxane, waste Fiber 5 servings.

[0032] The processing method of composite powder comprises the steps:

[0033] (1) Wash the egg shells and remove the film, dry and grind them into 2000-mesh fine powder;

[0034] (2) Take 1 kg of egg shell powder, add 50 g of zinc nitrate, 20 g of magnesium carbonate, 10 g of sodium hydroxide and 2.5 kg of pure water to form a solution, and stir for 2 h. After mixing evenly, use spray drying to remove the moisture in the powder.

[0035] (3) Mix the rice husk ash and the egg shell powder obtained in step (2) in a weight ratio of 1:2 with a dry powder mixer and put them into a muffle furnace, set the temperature at 1100 °C, and calcined for 5 hours. Pulverize the block to get composite powder.

Embodiment 2

[0043] The steps of Example 2 are the same as in Example 1, except that the amount of composite powder added in Example 1 is changed to 130 parts.

Embodiment 3

[0045] The steps of Example 3 are the same as in Example 1, except that the waste fibers in Example 1 are changed into rice husk fibers.

Abstract

The invention discloses bio-based soft porcelain and a preparation method thereof. The bio-based soft porcelain is prepared from the following raw materials in parts by weight: 100 to 130 parts of composite powder, 40 to 60 parts of polyacrylate emulsion, 8 to 15 parts of silane coupling agent, 5 to 10 parts of polyether polyurethane, 5 to 10 parts of polydimethylsiloxane and 5 to 8 parts of waste fiber. The bio-based soft porcelain is prepared through the processes of stirring, mixing, compression molding, drying and the like. Herein, the egg shells, the rice hull ash and the waste fibers are used as raw materials, so that recycling of waste resources can be achieved to the maximum extent, and the prepared bio-based soft porcelain has the effects of resisting bacteria, adsorbing and decomposing toxic gas, adjusting humidity and the like. The method is simple in process, low in cost, environment-friendly and rich in material source.

Description

technical field [0001] The invention relates to the technical field of building materials and decoration materials, in particular to a bio-based soft porcelain and a preparation method thereof. Background technique [0002] The annual output of eggs in China is 5.6 million tons, and the output of eggshells is about 610,000 tons. Although my country has abundant eggshell resources, there is no effective treatment mode. There are very few manufacturers who process and utilize eggshells, and the development and research of eggshells is also very small. weak. At present, a large number of eggshells produced by food processing factories can only be treated as garbage, causing environmental pollution and waste of resources; in 2020, the output of rice is 212 million tons, of which rice husks are about 42 million tons. well developed and utilized. In recent years, in order to solve the problem of effective utilization of rice husk, power plants using rice husk as fuel have been bu...
