Abstract

The invention relates to the field of plate processing technologies, in particular to a modified PET thick plate and an extrusion molding method. The modified PET thick plate is processed from a modified PET material. The modified PET material comprises the following raw materials by weight: 80-120 parts of PET resin, 1-10 parts of a processing modifier, 20-40 parts of a plasticizer, 10-20 parts of filler, 6-10 parts of a stabilizer, and 1-3 parts of a lubricant. The processing modifier is prepared by taking mineral filler as the carrier, adding 1, 4-cyclohexanedimethanol and performing blending. According to the invention, by adding the processing modifier into PET resin, the prepared PET material has greatly enhanced heat resistance and machining deformation resistance on the basis of maintaining the original properties. The modified PET thick plate provided by the invention has the advantages of good toughness, excellent heat resistance, excellent temperature resistance and weatherability, high strength, excellent shock resistance, good flame retardance, excellent processability, and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a modified PET thick plate and an extrusion molding method thereof. Background technique [0002] PET plastic is one of the plastics with outstanding comprehensive properties among thermoplastics. It is an amorphous transparent PET sheet or film obtained by blistering, blow molding or extrusion, and is used in containers in medical, food hygiene and other industries. Or packaging, as well as many areas such as X-ray film and motion picture film. PET plastic has many excellent properties, but due to the bottleneck problem of material crystallinity control in the process of extrusion molding industry (brittleness occurs when high crystallization occurs), PET plastic is extended in the extrusion of relatively thick plate products. are greatly restricted. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpo...
