Abstract

The invention discloses an EPS foam packaging plate for a washing machine and a preparation process of the EPS foam packaging plate. The packaging plate comprises a base material layer and a decorative layer, wherein the decorative layer is attached to the outer side of the base material layer, and is prepared from the following materials in parts by weight: 90-112 parts of polyphenylene propylene, 21-25 parts of bamboo charcoal fiber, 24-28 parts of diatomite powder, 11-14 parts of talc powder, 4-5 parts of aluminum hydroxide powder, 2-3 parts of antimony trioxide, 2-5 parts of a stabilizer,1-3 parts of a foaming agent and 1-3 parts of a compatibilizer. The base material layer of the EPS foam packaging plate is prepared in advance and coated with a flame-retardant polyether polyol material, and the bamboo charcoal fiber is adhered in a grid shape to form a decorative layer. By means of compatible mixing of all the components and cooperation with the compatilizer, uniform distributionof all the components of the whole EPS foam packaging plate is achieved during polystyrene foaming, so that the overall flame-retardant effect is improved.

Description

technical field [0001] The invention belongs to the technical field of spare parts of household appliances, and in particular relates to an EPS foam packaging board used for washing machines and a preparation process. Background technique [0002] With the continuous development of science and technology, EPS foam, also known as polystyrene foam, is a light polymer. It uses polystyrene value to add foaming agent, and softens in a heated environment to generate gas to form a hard foam. Foam plastic with closed cell structure. [0003] EPS foam packaging board has strong plasticity and is often used in the packaging industry, especially in the transshipment packaging of large household appliances. It is used to wrap large household appliances to prevent them from being knocked. In the production process, although a certain amount of flame retardant is added, the uniformity of the flame retardant and polystyrene raw materials cannot be guaranteed when mixed, resulting in uneve...
