A kind of handicraft clay plastic material and preparation method thereof

Abstract

The invention discloses a handicraft clay plastic material, which is made of the following raw materials in parts by weight: 2 to 3 parts by weight of borax, 1 to 2 parts by weight of ammonium dihydrogen phosphate, 4 to 6 parts by weight of magnesium oxide, and 0.5 to 1 part by weight of chlorine Aluminum chloride, 0.5-1 parts by weight of sodium humate, 50-60 parts by weight of kaolin, 10-20 parts by weight of calcium carbonate, 30-40 parts by weight of quartz powder, 10-20 parts by weight of muscovite powder, and 1-3 parts by weight of gypsum , 0.5 to 1 part by weight of hydroxyethyl cellulose, and the total water content is the required amount until the product becomes doughy and plastic. The handicraft clay plastic material of the present invention can be used under any conditions, the formula is reasonable and scientific, the raw material is easy to obtain, the cost is low, it is easy to disperse and stir, and the surface of the work is not easy to dry and crack during the hardening process, and the surface is dense and smooth. It can be widely used in sculpture, clay sculpture, models etc. The invention also discloses a preparation method of the handicraft clay plastic material. The preparation method has simple process steps and strong operability.

Description

technical field [0001] The invention relates to the technical field of clay sculpture, in particular to a handicraft clay sculpture material and a preparation method thereof. Background technique [0002] There are many kinds of clay sculpture artworks and a long history. It is a popular art form of our people and has strong local characteristics of China. Traditional clay plastic materials use clay as raw material, add various additives, and adjust the viscosity with water. However, the traditional clay plastic materials take a long time to harden, which usually takes a few days or longer, which is easy to cause deformation and collapse of the handicraft. In order to shorten the hardening time, the handicraft is usually hardened at high temperature. High temperature hardening consumes a lot of energy, and it is easy to cause cracks on the surface of the handicraft. .

AI Technical Summary

Problems solved by technology

Its disadvantages are: the hardening time of the sculpture mud is too long, at least 8 hours to harden; glutinous rice flour is added to the sculpture mud to improve the bonding strength, but the glutinous rice flour is easy to ferment, moldy and corrupt when the temperature is high and the humidity is high. , the fermented glutinous rice flour has a sour odor, surface foaming, long green hairs, greatly reduced viscosity, which affects the normal bonding process, which limits the application of the sculpture clay. At the same time, the glutinous rice flour is easy to agglomerate and difficult to stir Dispersion; the surface of the sculpture clay is easy to crack during the hardening process
