Problems solved by technology

Traditional ultra-light clay uses boric acid or borax as a cross-linking agent to form agglomerates, but boric acid and borax are toxic to a certain extent and are likely to cause harm to children's health, and have always been controversial in terms of environmental protection
Moreover, the ultralight clay prepared by boric acid or borax has poor agglomeration stability

Abstract

The invention provides ultra-light clay and a preparation method thereof. The ultra-light clay is prepared from the following raw material components in percentage by mass: 20%-50% of rubber powder, 45%-75% of water, 2%-5% of foaming powder and 1%-5% of glutaraldehyde. The ultra-light clay is prepared through the following steps: mixing the formula amount of water and glutaraldehyde firstly, adding the formula amount of foaming powder for mixing, and finally, adding the formula amount of rubber powder for mixing to obtain the ultra-light clay. Compared with traditional boron-containing ultralight clay, the provided ultralight clay is nontoxic and environmentally friendly, and has better aggregation stability.

Description

technical field [0001] The invention belongs to the technical field of paper clay, and in particular relates to an ultralight clay and a preparation method thereof. Background technique [0002] Paper clay, surface clay, and pottery clay are commonly used kneading materials, and are often used to make clay figurines, ornaments, paintings, etc. Paper clay is easy to obtain and store, it can be kneaded anywhere, and it can be colored freely. It is not like ceramics that need to be grilled. Using it to create has the pleasure of direct contact like playing with clay, and can be directly added to watercolor or Painted with watercolor, acrylic paint, oil paint and other paints, it is popular in modern society. [0003] Super-light clay (Super-Light Clay) is a kind of paper clay, referred to as super-light clay. It is easier and more comfortable to knead, and more suitable for modeling. It is a hand-made modeling material that can be dried naturally in Japan. [0004] Ultra-ligh...
