Description

Polymer polymer ceramic clay and preparation method thereof Technical Field The invention relates to the field of high-molecular polymerization clay, in particular to high-molecular polymerization clay and a preparation method thereof. Background With the development of social economy and the improvement of the living standard of people, the DIY hand-made product market presents a rapid development situation. From the child primary entry plasticine, rice clay and ultra-light clay to the super clay, stone-plastic clay and the like used by art professionals, DIY products are increasingly rich in variety, and the creation demands of consumers of different ages and different levels are met. The hand modeling materials sold in the market at present mainly have the following types and defects that 1. The plasticine and the rice clay are the most basic hand modeling materials for children and are mainly prepared by taking flour, water, food color and the like as raw materials. The product has the obvious defects of high safety and low price, does not have the modeling maintaining capability, is easy to crack and deform in the drying process, cannot be stored for a long time, usually cracks or mildews after a few days, has single color and poor plasticity, is only suitable for primary enlightenment education of children, and cannot meet the fine modeling requirement. 2. Ultralight clay is a popular light handmade material in recent years, and the main components of the ultralight clay are foam powder, water, adhesive and the like. Its advantages are light texture and rich colours. But the defects are also obvious that the product has similar texture to foam after drying, low density and poor strength, does not have ceramic texture, has rough surface, cannot be finely carved, is easy to absorb moisture and deform and yellow and age after long-term storage, and has no permanent preservation value. 3. The stone-plastic clay takes natural stone powder as a main raw material, has hard texture after drying, has stone-like texture and can be permanently stored. But has the defects of rough hand feeling, poor ductility, easy cracking in the molding process, water addition and kneading, inconvenient operation, long drying time of 24-48 hours, low efficiency, and pungent smell, and partial products contain pungent components, thus being not suitable for children. 4. Super clay (also called as American clay) is a professional hand-made material, uses polymer resin as base material, and possesses excellent plasticity and detail expressive force. However, the novel plastic composite material is high in price, difficult for common consumers to bear, hard in handfeel, high in kneading force, unsuitable for teenagers and female users, high in operation threshold and capable of being baked and cured at a specific temperature. 5. The traditional soft clay is also called polymer clay, and is generally prepared from polyvinyl chloride resin powder, liquid paraffin oil, phthalate plasticizers and other auxiliary agents. Although the products have certain plasticity and preservation value, the environmental protection performance is poor, the traditional polymer clay often uses phthalate plasticizers (such as DBP, DOP and the like), and various researches prove that the substances have endocrine disrupting effects, and the countries and regions of European Union, the United states and the like have strictly limited the use of the substances in toys and children products. The stability is poor, and heavy metal stabilizers such as lead salt, cadmium salt and the like are often used in the traditional formula, and the heavy metal stabilizers are harmful to human bodies and can cause toxic smog to be released in the baking and using processes of the product. The hand feeling is sticky, and the traditional soft clay is easy to stick hands and tools in the molding process, so that the operation experience and the fineness of the work are affected. And (3) oil is discharged after drying, namely, oil substances ooze out of the surface of a part of traditional products after baking and curing, the appearance of the product is destroyed, and dust is easy to be stained. The aging and hardening are easy to occur in the sealing and preserving process of the traditional soft clay, and the traditional soft clay cannot be stored for a long time. Aiming at the defects of the traditional soft clay, the prior art has a part of reports on improvement technology. For example, patent literature discloses a method for producing a polymer clay based on a polyvinyl chloride paste resin, to which a liquid paraffin oil, a phthalate plasticizer and a lead salt stabilizer are added. However, as mentioned above, such techniques still have drawbacks in terms of environmental protection and usability. In addition, the citric acid ester environment-friendly plasticizer is tried to replace phthalate, but the problems of heavy metal of a stabilizer and anti-sticking and
