Abstract

The invention relates to a PU (Polyurethane) toy, particularly relates to a foamed toy, and belongs to the technical field of foamed materials. The PU toy provided by the invention is prepared from aPU foamed material, wherein the PU foamed material is prepared from the following components in parts by weight: 48 to 62 parts of a polyurethane black material, 54 to 65 parts of a polyurethane whitematerial, 6 to 12 parts of preserved peony flower, 3 to 5 parts of cellulose microfibril, 5 to 10 parts of a carbon fiber, 3 to 5 parts of a foaming agent and 3 to 5 parts of a wetting agent. The PUtoy is prepared by adopting the PU foamed material; the safety and elasticity of the PU toy are increased by adding the preserved peony flower into the PU foamed material; the strength and toughness of the PU toy are enhanced by the cellulose microfibril; a foam structure of the PU toy is improved by the carbon fiber; and the prepared PU toy is enabled to be high in strength, good in elasticity and further uniform in structure.

Description

field of invention [0001] The invention relates to a PU toy, in particular to a foamed toy, which belongs to the technical field of foamed materials. Background technique [0002] Toys are indispensable in the growth process of children. Appropriate toys can not only bring happiness to children, but also increase children's interest in science and improve their ability to explore nature. Due to the rapid development of economy and society, more and more kinds of toys are put into the market, winning the favor of children. Various children's toys are sold on the market now, and due to the influence of martial arts TV, swords and the like are very popular among children as a kind of toys. Boys in particular like to imitate heroes on TV, and toy swords as imitation props can add a lot of fun to children's lives. [0003] At present, most of the toys sold in the domestic market are formed in a cylindrical shape, the plastic is hard, and the abdomen is filled to achieve the exp...
