Problems solved by technology

[0003] However, the existing water-based paint avoids the addition of toxic and harmful components on the solvent, but it still cannot avoid the release of toxic substances caused by plastic aging and other problems, and the anti-fouling ability is not enough, and it absorbs the external environment and causes direct contact with children. Therefore, it is necessary An environmentally friendly and non-toxic coating, which can avoid the harm caused by plastic aging and has excellent antifouling ability, avoiding the adsorption of toxic and harmful substances

Abstract

The invention relates to the field of energy-saving environment-friendly new material industry and discloses an environment-friendly nontoxic coating suitable for toys of children. Low-cost raw materials E-44 epoxy resin and trimethyl hydroxy silane are selected and modified with zinc borate and Ce / TiO2 nanometer hybridized mixture, so that the toxic substances, such as dioxin and plasticizer released from plastic toys, and the hazardous substances, such as benzene and aldehyde, in air can be decomposed; the prepared modified organic silicon resin has ultrahigh heat stability and excellent anti-ultraviolet property, can solve the problem of easiness in ageing and cracking of inner plastic caused by the factors of illumination, temperature, and the like, is capable of releasing sterilizingions and has a photocatalytic antibacterial function; during the process of coating preparation, the modified organic silicon has high compatibility with other additives, the silane macromolecule is high in surface energy, the contact angle between liquid and the silane macromolecule is obviously reduced, the dispersing capacity is high and the pollution resistibility is strong; the modified organic silicon is an environment-friendly nontoxic coating suitable for toys of children.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly new material industry, and in particular relates to an environment-friendly and non-toxic coating suitable for children's toys. Background technique [0002] China's toy exports account for an important proportion. With the introduction of relevant regulations in some western countries, solvent-based coatings have been banned. Coupled with the user's own safety and health needs, the coatings industry has also ushered in a transition period to safe and environmentally friendly coatings. Environmentally friendly water-based coatings will gradually replace solvent-based coatings. Professionals predict that domestic environmentally friendly water-based coatings will have more than 10 times the growth potential. Statistics show that water-based paints are more widely used in children's toys. Children and teenagers have weak constitutions and sensitive respiratory tract...
