DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be described below in a clear and complete manner. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0016] Embodiment

[0017] A temperature-variable soft light bar lamp strip processing technology, comprising a light bar raw material and a temperature-sensitive color-changing powder. In the embodiment, the light bar raw material is a rubber raw material, a silica gel raw material or a plastic raw material. The plastic raw material includes PC, PVC, PMMA or ABS. Polycarbonate (PC for short) is a kind of thermoplastic engineering plastic with carbonate groups (-O-CO-O-) in the molecular backbone.

[0018] Polyvinyl chloride plastic (PVC, trade name "chlorine plastic") is a thermoplastic plastic polymerized from vinyl chloride monomer.

[0019] Poly (methyl methacrylate) plastic (PMMA), also known as acrylic, organic glass or acrylic, is a thermoplastic plastic polymerized from methyl methacrylate.

[0020] The processing steps are as follows: Step A, the temperature-sensitive color-changing powder and the light bar raw material are prepared according to a certain mass component; in step A, the mass components of the temperature-sensitive color-changing powder and the light bar raw material are as follows: 18-30 parts of temperature-sensitive color-changing powder, and the rest is light bar raw material. Specifically, in step A, the mass components of the temperature-sensitive color-changing powder and the light bar raw material are as follows: 25 parts of temperature-sensitive color-changing powder, and the rest is light bar raw material.

[0021] Meanwhile, in step B, the raw materials in step A are heated respectively, and after being heated to the corresponding temperature, they are sent into a co-extrusion die for co-extrusion molding. In step B, the corresponding temperature is less than or equal to 230°. In step B, the co-extrusion molding is a single-layer light bar or a multi-layer light bar. The above-mentioned process is beneficial to improve the processing efficiency and the processing quality. The extrusion process is to use two or more extruders to melt different raw materials, and then introduce them into a shared composite head, and then converge and extrude at the same time.

[0022] The present invention has the following positive effects: the process of the present invention is simple, which is conducive to improving processing efficiency. Furthermore, the co-extrusion molding operation can improve the effectiveness of the light strip. Moreover, it is mixed with thermochromic powder, so when the lamp is lit, the color of the light strip will change as the temperature of the lamp rises. This not only helps to improve the lighting and decorative effect, but also helps to judge the temperature of the lamp, which can meet the usage needs of different situations.

[0023] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0024] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
