Abstract
The invention discloses a magnetic sheet toy and a preparation method thereof. The magnetic sheet toy comprises a shell, and a magnet and a gasket which are positioned in the shell, the shell comprises the following raw materials in parts by weight: 1-3 parts of an antioxidant and 1-3 parts of a lubricant, and the composite material is prepared from 30-50 parts of resin base material, 15-20 partsof anion modified polyesterfiber, 10-20 parts of PVC paste resin / opal composite material, 15-20 parts of anion viscosefiber, 7-13 parts of compatilizer, 2-5 parts of antioxidant, 5-10 parts of silanecoupling agent, 6-12 parts of organic antibacterial agent and 5-15 parts of flame retardant. The magnetic sheet toy has the advantages that air can be purified, the air quality of the infant teaching environment is improved, the antibacterial rate is good, the antibacterial effect is good, the washability is good, and after being washed many times, the magnetic sheet toy still has the high negative ion release amount and antibacterial rate.
Description
technical field [0001] The invention relates to the technical field of plastic products, more specifically, it relates to a magnetic sheet toy and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the requirements for the quality of life have become higher and higher, and the cultivation of young children has also paid more and more attention. Most families first consider the development of the intelligence of young children.
