Embodiment 1

[0024] The preparation method of the silicone baking pan includes the following technical steps: (1) adding aluminum powder accounting for 5% of the total product weight and 1% of the total product weight to the commercially available high-temperature vulcanized and kneaded silicone rubber with a hardness of 70 degrees The carbon black is used as a colorant and a C-5 (double 2,5) vulcanizing agent, which accounts for 1% of the total weight of the product, is mixed into a solid silicone rubber compound by an open mill;

[0025] (2) Slice the solid silicone rubber compound into films with a thickness of 3 mm, put it into a baking pan mold on a molding press with a pressure of 200 tons, and continue to pressurize it at a high temperature of 170 ° C for 300 seconds to make a baking pan blank ;

[0026] (3) Trimming the formed baking pan blank to remove burrs, and making a silicone baking pan through secondary vulcanization at a high temperature of 200° C. for 4 hours.

Embodiment 2

[0028] The preparation method of the silicone baking pan includes the following technical steps:

[0029] (1) The commercially available AB two-component liquid silicone rubber with a hardness of 70 degrees is added into the A agent and the B agent, respectively, adding aluminum powder that accounts for 5% of the total product weight, mixed into the mixer, and then adds 1% of the total product weight. Carbon black is used as a pigment, and it is fully stirred and processed into liquid silicone rubber (LSR);

[0030] (2) The liquid silicone rubber is injected into the baking pan mold on the molding machine with a pressure of 100 tons through a horizontal injection machine, and is continuously pressurized at a high temperature of 130 ° C for 80 seconds to make a baking pan;

[0031] (3) Trimming the formed baking pan blank to remove burrs, and making a silicone baking pan through secondary vulcanization at a high temperature of 200° C. for 4 hours.

[0032] Compared with the pr...

Abstract

The invention discloses gel silica baking pot and its preparation methods. The gel silica baking pot the invention is formed by adopting combination molding pressing or ejecting and sulfurizing of multi-component, and its composition are silicone rubber, thermal conductivity agent, vulcanizing agent. Gel silica baking pot using the technology program of the invention, under the same conditions, the cake or bread using the present product has better sallow effects than that using traditional gel silica baking pot, and in particular, makes shape, color and taste of the baked cake have the same desired effect as that of the traditional metal baking pot.

Description

technical field [0001] The invention relates to the field of baking equipment, in particular to a silica gel baking tray and a preparation method thereof. Background technique [0002] The baking pans for traditional baked cakes and other foods are all made of metal, and there are also baking pans made of silicone rubber. However, compared with metal, traditional silicone rubber has poor thermal conductivity. When making baking pans, baked cakes The appearance, color and taste are difficult to achieve the ideal effect of traditional metal baking pans. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and to provide a convenient, hygienic and recyclable silicone baking tray which is very suitable for baking and making cakes. [0004] Another object of the present invention is to provide a preparation method of the silica gel baking pan. [0005] In the present invention, it is found through researc...
