Method for producing composite layer substrate of trunk ornamental plate for automobile

Abstract

The invention relates to a method for producing a composite layer substrate of a trunk ornamental plate for an automobile, which can be particularly applied to manufacturing a composite layer of the trunk ornamental plate for the automobile. The method is characterized by comprising the following steps: taking PET as a bonding substrate; coating PP on the bonding area on the surface of a PET blanket; putting into an oven, heating, drying and taking out; and then pressing the substrate by a presser, and cutting by a cooling water cutter to obtain a finished product. The invention has simple technology and equipment requirement, stable technology, avoids investing for establishing large-scale equipment, ensures safety and accuracy of operation, and improves the operating efficiency. The finished product has the advantages of high resistance to high and low temperature, ageing resistance, good bending resistance, high rigidity and no breakage or droop; no semi-finished product accumulatesduring transportation so that the manufacturing cost is saved; and no harmful matter is generated in the whole production process.

Description

technical field [0001] The invention relates to a production method of a base material of a composite layer of a trim plate of an automobile trunk, and in particular can be applied to making a composite layer of a trim plate of an automobile trunk. Background technique [0002] PET (polyethylene terephthalate), as a high-molecular compound with extremely high molecular weight, has high elasticity characteristics that are lacking in general materials. It has excellent physical and mechanical properties in a wide temperature range. It has a certain hysteresis effect on alternating and vibration stress and fluctuation, so it has the function of sound insulation and shock absorption. In addition, its heat resistance, chemical resistance, toughness, electrical insulation, safety and other advantages also promote the development of the PET industry. the popularity of its products. However, PET has poor impact performance, weak rigidity and is easy to deform. Contents of the in...
