Swelling agent for manufacturing toy

Abstract

The invention belongs to the technical field of swelling materials and particularly relates to a swelling agent for manufacturing a toy. The swelling agent comprises the following components in parts by weight: 40-60 parts of white alum, 30-36 parts of calcium oxide, 20-25 parts of scrap iron and 18-24 parts of calcium sulphoaluminate. The swelling agent is simple in composition and easy in obtaining of raw materials; by adopting the swelling agent for manufacturing the toy, the swelling effect of the toy can be enhanced, the service life of the toy can be prolonged and the material is environmentally friendly and harmless.

Description

technical field [0001] The invention belongs to the technical field of expansion materials, in particular to an expansion agent for making toys. Background technique [0002] Nowadays, the types of toys are really varied and varied. Among them, expansion toys made of the principle of thermal expansion and cold contraction are more and more popular among children. This type of toy expands in hot water and can float on the water surface. It is a good companion for children to take a bath; after cooling down, it will Shrink, take up less space. However, the existing inflatable toys usually have a short service life, and their expansion and contraction effects will be greatly reduced after being used several times, which is closely related to the composition of their materials. Contents of the invention [0003] The invention aims at the deficiencies in the prior art, and provides an expanding agent for making toys that can prolong the service life of the toy and is envi...
