Description

Technical Field

[0001] The invention relates to the technical field of composite materials, and in particular to a production process of a high-performance TPO composite material. Background Art

[0002] Composite materials refer to new materials that are formed by optimizing and integrating material components of different properties using material preparation technology. Composite materials have the advantages of different raw materials and can make up for some of the shortcomings of the raw materials. Through the complementarity of advantages, disadvantages and characteristics between materials, they achieve comprehensive performance that cannot be achieved by a single material. Alloys, synthetic resins, rubber, ceramics, etc. are all relatively common composite materials.

[0003] TPO is usually a copolymer of ethylene and octene, a new type of rubber with excellent properties. It is widely used in life. As an outdoor fabric, tarpaulin is used outdoors for a long time. The temperature difference between day and night and long-term exposure to the sun cause the fibers of the tarpaulin to break and be damaged. Therefore, a production process of high-performance TPO composite materials is proposed. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a production process of a high-performance TPO composite material. The TPO composite material has good strength, flexibility, soft feel, and good weather resistance. It can perfectly replace outdoor fabrics such as awnings, and the TPO composite material has strong practicality.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a production process of a high-performance TPO composite material, which completes the production process of the high-performance composite material through the steps of raw material selection, raw material mixing, composite molding, surface treatment, embossing treatment, finished product winding, etc.; the specific steps are as follows:

[0006] S1. Raw material selection: mesh, TPO particles, PP particles, EVA particles;

[0007] S2, raw material mixing: the TPO particles, PP particles, and EVA particles in step S1 are mixed and melted;

[0008] S3, composite molding: placing the mesh in step S1 on a composite device and composite it with the raw materials mixed in step S2 to form a finished blank;

[0009] S4, surface treatment: the finished blank compositely formed in step S3 passes through a surface treatment station, where a surface treatment agent is applied to the surface of the finished blank;

[0010] S5, embossing treatment: the finished blank which has been surface treated in step S4 is embossed by an embossing roller to form a finished product;

[0011] S6, Finished product winding: The winding roller at the rear of the composite equipment winds up the finished product, completing the production process of high-performance composite materials.

[0012] Preferably, the weight proportions of the raw material mixing process in step S2 are: 100 parts of TPO, 5 parts of EVA particles, and 5 parts of PP particles. During the mixing process, 18 parts of fire retardant, 0.3 parts of anti-UV additive, 2 parts of antioxidant, and 2 parts of light stabilizer are added.

[0013] Preferably, the composite molding process in step S3 is specifically as follows: placing the mesh on the composite equipment, connecting the first nozzle to the first melt extruder, connecting the second nozzle to the second melt extruder, the first nozzle spraying the first melt onto the mesh, and the second nozzle spraying the second melt onto the surface of the first melt on the mesh, the first melt and the second melt passing through the casting cooling station on the mesh to form a cast film, and the cast film and the mesh are composited by a composite pressure roller to form a finished blank.

[0014] Preferably, the surface treatment agent of the surface treatment process in step S4 is specifically: water-based silica gel or water-based PVDF or water-based PMMA.

[0015] Preferably, polyurethane particles are added into the first melt extruder, and TPO particles and EVA particles are added into the second melt extruder.

[0016] Preferably, the first nozzle and the second nozzle are respectively arranged on both sides of the surface of the fabric, and the second nozzle is located outside the first nozzle.

[0017] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0018] The TPO cast film is compounded on the surface of the mesh to encapsulate the mesh, and EVA is compounded on the surface of the mesh to make the mesh soft and have a certain flame retardant effect. Both PP and TPO have good weather resistance, which is convenient for improving the service life of the mesh. After use, TPO can be recycled to make other materials, such as car fenders, and after the fenders are damaged, they can be recycled again. It has good environmental performance and high-performance TPO composite materials are highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
