AI Technical Summary

Problems solved by technology

The existing self-adhesive protective film manufacturers in the market have problems such as low viscosity, abnormal viscosity increase with temperature increase, difficult production and processing, and narrow product use range because the adhesive layer uses relatively single-functional raw materials.

Embodiment Construction

[0017] A production process of a self-adhesive protective film, comprising the following steps: (1) After heating a screw and a mold to a predetermined temperature, the raw materials of the prepared adhesive layer, physical property layer and unwinding layer are respectively put into the corresponding (2) The raw materials of each layer flow to the mold body of each layer after being sheared and plasticized by the corresponding screw; (3) The single-layer melt is evenly distributed and merged in the flow channel of the mold body, and the process is carried out from bottom to top. The superposition of each layer forms a multi-layer composite melt; (4) Through the circular mold mouth, the melt is blown to the set width by the pressure of compressed air, and the bubble shape is shaped by the purified external cold air, and then Winding and slitting into customer demand products.

[0018] The thickness ratios of the above-mentioned unwinding layer, physical property layer, and adh...

Abstract

The invention discloses a self-adhesive protective film and a production technology thereof. The self-adhesive protective film comprises a bonding layer, a physical property layer and an unwinding layer, and the bonding layer is made from SEBS and tackifying resin C5 which serve as raw materials; the physical property layer is made by mixing the three raw materials of LLDPE, HDPE and MLLDPE; the unwinding layer is made from LDEP serving as the raw material. Accordingly, the application range is greatly widened, the controllability and stability of the product processing process are improved, and the rejection rate is lowered. Meanwhile, the problem that in a traditional technology, bonding layer distribution is uneven is solved, and the product quality is greatly improved.

Description

technical field [0001] The invention relates to a protective film, in particular to a self-adhesive protective film for a home appliance color steel plate and a production process thereof. Background technique [0002] Household appliances are extremely vulnerable to damage and pollution during production, processing, assembly, and transportation. The existing self-adhesive protective film manufacturers in the market have problems such as low viscosity, abnormal viscosity increase with temperature increase, difficult production and processing, and narrow product use range because the adhesive layer uses relatively single-functional raw materials. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art, and provide a production process of an improved self-adhesive film product home appliance color steel plate self-adhesive protective film with more complete functions and more in line with customer u...
