Problems solved by technology

[0003] Since thermoplastic polyolefin elastomer films are usually relatively expensive, the use of thermoplastic polyolefin elastomer films to make the skin layer of automotive interiors can provide a soft touch, while improving the grade of automotive interiors, it also virtually increases the cost of raw materials
At the same time, lightweight has become the development trend of the automotive industry, but the current interior skin materials have little consideration for lightweight development

preparation example Construction

[0038] In the fifth aspect, the present invention also provides a method for preparing a surface decoration composite material, the preparation method comprising the following steps: S1, sequentially extruding, molding, and cooling the polyolefin masterbatch according to the present invention to obtain a polyolefin Film; S2. Heating one side surface of the polyolefin film to melt it to form a melting surface to be embossed, and then bonding the foam layer to the other side surface of the polyolefin film and performing lamination-pressing The flowers are processed to obtain composite materials.

[0039] According to the preparation method of the present invention, the steps of extruding and forming the polyolefin film masterbatch can be carried out in a three-roll calender. For specific operating conditions, reference can be made to conventional operating conditions in the art. Taking the steps of extruding and molding with a three-roll calender as an example, the operating pa...

Abstract

The invention discloses a polyolefin composition, a polyolefin masterbatch, a polyolefin film and a surface decorative composite material and a preparation method of the surface decorative composite material. The composition comprises, in parts by weight, 100 parts of a polyolefin system, 0.01-3 parts of a crosslinking agent, 0.01-3 parts of a crosslinking assistant and 0.1-10 parts of a microsphere expansion agent when the weight of the polyolefin system is counted as a standard, wherein the crosslinking agent is an organic peroxide crosslinking agent, and the cross-linking assistant is an acrylate crosslinking assistant and / or a polybutadiene-based crosslinking assistant. The microsphere expansion agent is added, and a mode of microsphere expansion is adopted to replace the mode of gas foaming, so that not only can the density of the formed polyolefin film be reduced, but also no formation of pinholes in the surface of the formed polyolefin film can be achieved, and the surface structure of the polyolefin film is dense, soft and comfortable.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a polyolefin composition, a polyolefin masterbatch, a polyolefin film, a surface decoration composite material and a preparation method thereof. Background technique [0002] The scope of automotive interiors is mainly composed of instrument panels, door panels, roofs, seat cushions, wood grain finishes, sun visors, armrests, gear covers, etc. The material properties are very demanding, and they have high requirements for temperature resistance, weather resistance, odor, appearance, Wear resistance and other requirements are very strict. Among them, the structures of instrument panels, door panels, armrests, roofs, seat backs, etc. are basically the same. At present, the skin layers of these automotive interiors are increasingly using thermoplastic polyolefin elastomer films (TPO or TPV) . [0003] Since thermoplastic polyolefin elastomer films are usually relatively expensi...
