Abstract

The invention discloses a refrigerator backboard with a flame-retardant function. The refrigerator backboard comprises, by weight, 90-150 parts of polybutylene terephthalate, 40-60 parts of filling agent glass fibers, 40-100 parts of halogen-free flame retardants, 2.0-3.0 parts of toughening agents, 0.2-0.5 part of silane coupling agents, 0.3-0.7 part of antioxidants, 0.3-0.6 part of lubricating agents and 2.5-5.0 parts of dibutyltin dilaurate. The refrigerator backboard is novel in scheme and reasonable in formula and has the advantages of flame resistance and high hardness, and the performance of the refrigerator backboard can be effectively improved by the preparation method.

Description

technical field [0001] The invention relates to the technical field of refrigerator backboards, in particular to a refrigerator backboard with a flame-retardant function. Background technique [0002] The backboard of the refrigerator is a partition used to protect the internal equipment of the refrigerator from being affected by the external environment. It has flame retardant properties, but its strength performance is still lacking. Contents of the invention [0003] The object of the present invention is to solve the disadvantage that the existing refrigerator backboard has flame-retardant performance but lacks strength performance, and proposes a refrigerator backboard with flame-retardant function. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A refrigerator backboard with flame-retardant function, comprising the following components in parts by mass: 90-150 parts of polybutylene terephthalat...
