Embodiment 1

[0015] The specific preparation process of the anti-ultraviolet APET composite film mentioned in the present invention is as follows:

[0016] a) Material selection and preparation, the APET composite film is composed of an inner layer and an outer layer. The inner layer is made of PE film with a thickness of about 0.07mm; the outer layer is made of APET sheet with a thickness of about 0.25mm; the function used when the two layers are combined The main components and percentage ratio of the compound agent are: triazine ultraviolet absorber 30%, acrylate adhesive 40%, and the rest are auxiliary agents; auxiliary agents include ethanol diluent, calcium-zinc composite stabilizer, Glyceryl tristearate dispersant, diphenylamine antioxidant, etc., the percentage of diluent accounts for about 18%-20%;

[0017] b) Prepare functional composite agent, the preparation process is as follows: First, add acrylate adhesive and related additives to the mixing tank, control the temperature of ...

Abstract

The invention discloses a method for preparing an uvioresistant APET composite film. The method comprises the following steps: a) selecting and preparing materials; 2) preparing a functional composite agent; c) performing dry compounding treatment; and d) performing after treatment on the film. The invention discloses a method for preparing the uvioresistant APET composite film. The method is reasonable in procedure arrangement, scientific in application process and moderate in cost; the prepared composite film is high in interlayer combination strength and excellent and stable in mechanical property and has an outstanding and long-lasting uvioresistant function, and the practicability of the APET film is effectively improved.

Description

technical field [0001] The invention relates to a preparation method of an APET film, in particular to a preparation method of an APET composite film with an anti-ultraviolet effect, and belongs to the technical field of APET products. Background technique [0002] APET film is a polyester sheet of plastic-absorbing material, also known as polyester hard tape. It belongs to thermoplastic environmental protection plastic products. Its side materials and waste products can be recycled. Degradable plastic. When packaged products made of this material are discarded, they end up as water and carbon dioxide. APET environmental protection film is widely used in the packaging of cosmetics, food, electronics, toys, printing and other industries, such as various high-end blister packaging, folding boxes, rubber tubes, windows, etc. At this stage, China already has relatively mature APET production technology, and its price is far lower than that of PETG sheet. [0003] APET film is...
