Description
Technical Field
The application relates to the technical field of synthetic leather, in particular to a special silicon rubber synthetic leather fabric for an automobile seat and a manufacturing process thereof.
Background
Polyvinyl chloride (PVC) synthetic leather, polyurethane (PU) synthetic leather's production, use and aftertreatment process have serious pollution, do not accord with the environmental protection requirement, and the silicon rubber synthetic leather has its unique advantage: the artificial leather has the characteristics of environmental protection, good weather resistance, stain resistance and the like, becomes a new hot spot in the field of artificial leather, and attracts the wide attention of people.
In the related technology, the silicon rubber synthetic leather is a composite material formed by sequentially bonding a textile substrate, a bottom layer adhesive and a surface layer adhesive, and the synthetic leather adopts a material containing Si-CH 2 ＝CH 2 The group vinyl silicone oil and the hydrogen-containing silicone oil containing Si-H group are subjected to hydrosilylation reaction under a platinum catalyst to prepare the synthetic leather.
In the related technology, because the silicon rubber molecular chain is very soft and smooth, the silicon rubber molecular chain is nonpolar, and the acting force between molecules is small, the strength of the unreinforced silicon rubber is very low, and the utilization value is not high, so that the wear resistance and the mechanical property of the silicon rubber type synthetic leather are poor, the application is limited, and the development of the silicon rubber with high wear resistance and high mechanical strength is urgently needed.
Disclosure of Invention
In order to improve the wear resistance of the silicon rubber synthetic leather fabric, the application provides a special silicon rubber synthetic leather fabric for an automobile seat and a manufacturing process thereof.
In a first aspect, the application provides a special silicone rubber synthetic leather fabric for an automobile seat, which adopts the following technical scheme:
the silicon rubber synthetic leather fabric is formed by sequentially bonding a fabric base, a bottom rubber layer and a surface rubber layer.
The surface glue layer is prepared from the following raw materials in parts by weight:
50-70 parts of vinyl-terminated polysiloxane;
10-30 parts of hydrogen-containing silicone oil;
4-9 parts of inorganic whiskers;
0.01-0.04 part of methylbutynol;
10-16 parts of methyl methacrylate;
0.02-0.07 part of benzoyl peroxide;
