Abstract

The invention relates to an expanding material form manufacturing an expansion toy and a manufacturing method of the expanding material for manufacturing the expansion toy. The expanding material provided by the invention for manufacturing the expansion toy is manufactured by EVA (ethylene-vinyl acetate copolymer), water uptake resin, talcum powder, milky white glue, zinc stearate, calcium carbonate superfine powder, TPR (thermoplastic rubber), titanium dioxide, oily table glue and C5 petroleum resin. The advantages of the expanding material for manufacturing the expansion toy are mainly embodied as follows: no toxicity and no pollution exists, the water swelling multiplying power is high, good flexibility is kept after water uptake, the physical strength and chemical properties are very stable, deformation is unlikely to occur, the storage time before water uptake and the service life after water uptake are long, and the shelf life before water uptake is over 12 months.

Description

technical field [0001] The invention relates to a material for making inflatable toys and a preparation method thereof. Background technique [0002] An inflatable toy is a toy that expands when it absorbs water, and its expansion rate is determined by the water expansion rate of the material. Existing expansion materials used to make inflatable toys are mainly composed of water-based components and oil-based components, the water-based components absorb water, and the oil-based components maintain the overall skeleton of the material. The existing swelling materials mainly have the following disadvantages: low water absorption expansion ratio, short storage time without water absorption, generally 4-5 months, no elasticity after water absorption expansion, easy deformation, poor stability, easy decomposition and deterioration, resulting in preparation The inflatable toys have low playability and short service life. Contents of the invention [0003] The purpose of the p...
