Abstract

The invention relates to elastic material for preparing elastic and flexible toys, and particularly relates to elastic flexible glue. The elastic flexible glue comprises the following components by weight percentage: simethicone, super fine calcium carbonate, boric acid, TPR (thermal plastic rubber), zinc stearate, silicon resin, bentonite, barium carbonate, linseed oil and erucyl amide. The elastic flexible glue provided by the invention has good elasticity and proper bulking intensity; the surface of the elastic flexible glue is smooth, good in hand feel, adhesive, and tough, and has good aging resistance, high stability and long service life that is from 13 to 15 months; and the elastic and flexible toys made of the elastic flexible glue have high quality, and are playable and durable.

Description

technical field [0001] The invention relates to an elastic material for making elastic soft toys and a preparation method of the material. Background technique [0002] Elastic soft rubber is a material used to prepare various soft animal toys, bouncy balls, jumping balls and other elastic soft toys. Such elastic soft toys have relatively high requirements for elasticity and feel. Existing elastic soft rubber is mainly made of simethicone, calcium carbonate and boric acid. This kind of elastic soft rubber has many deficiencies such as poor high temperature and low temperature resistance, low stability and perishability, especially easy aging, insufficient elasticity, low bulkiness and poor hand feeling, which make the quality of toys prepared by elastic soft rubber poor. Low playability. In terms of service life, the service life of the elastic soft rubber mentioned above is generally 7 to 8 months, which is very short. Contents of the invention [0003] The purpose of ...
