Nontoxic rubber color daub and preparation method thereof

Abstract

The invention discloses a nontoxic rubber color daub and a preparation method thereof. The preparation method is characterized by comprising the following steps: mixing 5 to 30 portions of rubber elastomer, 5 to 25 portions of white factice, 20 to 80 portions of mineral filler, 1 to 10 portions of bonding agent, 5 to 20 portions of plasticizing agent, 0.1 to 10 portions of pigment, and 0.5 to 3 portions of anti-aging agent with or without proper amount of auxiliary materials on a mixing machine at a temperature of 50 to 250 DEG C; and mixing the rubber elastomer and the white factice evenly first, then adding other components, and mixing the components evenly. The nontoxic rubber color daub is nontoxic and pollution-free, has strong temperature difference adaptability, good hand feeling and bright color, and can not only be used as a toy for children and a tool for artists to make models, but also can be used as a building joint filling material.

Description

technical field [0001] The invention relates to the technical field of a color mud mixture and a related manufacturing method. Background technique [0002] Colored clay has a wide range of uses as a toy for children or teenagers, as well as a tool for artists to shape or make models. To this end, scientific and technological personnel continue to make new improvements. [0003] For example, the Chinese patent application with the patent application number of 03111236.6 discloses a color mud and a production method, which is made from the following raw materials: 400-600 grams of paper mud, 5-15 grams of potassium pearate, and 5-10 grams of polyvinyl acetate emulsion. 15 to 35 grams of advertising pigments, put the raw materials in the above proportions into a container and stir evenly to form a finished product, and obtain a non-toxic and harmless color mud suitable for children's color mud painting and simple to make.
