Perhaps, (3) are combined into silicon rubber air-vent paper with glass fibre matrix and silastic-layer with the mould pressuring method.

Above-mentioned glass fibre matrix can adopt the glass fibre gauze of tool elastic effect and general plain weave not to have a glass fibre gauze of elastic effect.

Above-mentioned silicon rubber can reaction makes under the condition of catalyst existing by having raw material such as link crosslinking silicone material.For example, obtain the silicon rubber slurry after raw material such as vinylsiloxane by having link properties and the platinum catalyst interlinkage hybrid reaction, its process can be with reference to following formula:

(1) vinylsiloxane with+basic hydrogen siloxane+platinum catalyst → product arranged.

(2) vinylsiloxane with+basic hydrogen siloxane+peroxide → product arranged.

Certainly,, also can add silica reinforcing agent or the like in the above-mentioned reaction raw materials, so that the silastic-layer that forms has better toughness and anti-tear, tensile strength at the needs of actual conditions.

It is pointed out that in addition for making its standard that meets food sanitation safe, its silastic-layer should be a food-grade silicon rubber because of this silicon rubber air-vent paper mainly is the field that is applied to Food Contact.But the preparation technology of above-mentioned silicon rubber slurry also referenced patent number is the scheme that Chinese invention patent proposed of ZL02102780.3.

The multiple preparation technologiesization of this silicon rubber air-vent paper, and all succinctly easy to operate, simultaneously, its raw material sources are extensive, and are with low cost.

Compared with prior art, the beneficial effects of the utility model are: this silica gel air-vent paper good air permeability, and the heat conductivility excellence is not polluted by oil, water can, be easy to peel off with food, and be convenient to clean, simultaneously, multiple preparation technologiesization, simple and easy to operate, raw material sources are extensive, and are with low cost.The utility model is suitable for reusing in the digesting technoloy of various food.
