Adhesive glue and plastic foam products using the adhesive glue

Abstract

The invention disclose an adhesive gel which is characterized in that the adhesive gel is prepared from raw materials with the weight percentage of 12-20 percent of polyisobutylene with 400 million viscosity average molecular weights, 9-19 percent of liquid paraffin and 65-78 percent of gasoline or petroleum ether. A foam plastic product is composed of the adhesive gel and foam plastic particles according to the weight ratio of 2 to 1 to 4 to 1. The foam plastic product has the advantages of nontoxic performance, tasteless, no mouldiness and good plasticity. The foam plastic product can be deformed adhesively into various shapes, can not dry for a long time and can not disperse in water. And non-polar group in the polyisobutylene molecule structure in the adhesive gel is provided with weak viscosity to polar materials. Therefore, the foam plastic product can not stick to hands or other objects.

Description

technical field [0001] The invention relates to a colloid for bonding objects, in particular to an adhesive glue and a foam plastic product using the adhesive glue. Background technique [0002] There are many kinds of DIY educational toys for children on the market at present, and plasticine is one of them. It can allow children to give full play to their imagination and pinch out various shapes they imagine at will, which is beneficial to children's intellectual development. Plasticine also has many disadvantages, such as: over time, it is easier to dry, because the raw material of plasticine is mostly calcium carbonate powder, and the color pigment used in the colored plasticine contains heavy metal ions, the powder of plasticine is easy to dry after drying. If it falls off, it will adhere to the children's hands, be taken into the mouth by the child, or be directly inhaled by the child's nasal cavity, which will affect the health of the child.
