Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of a silicone dough kneading mat with long aging resistance and long service life. Background technique [0002] Silicone kneading mat is often used in food pretreatment, has excellent anti-stickiness, can easily remove oil stains, stains, etc. on the surface with hot water or detergent, and can be used repeatedly; it has good temperature resistance, and the conventional temperature resistance can reach above 200 ℃; Good softness and easy storage. The non-stick and temperature-resistant properties of the silicone kneading mat make it better for food processing, and it can also be used as a placemat, table mat, heat insulation mat, etc. It is an indispensable item in the kitchen. However, most existing kneading pads have problems such as poor aging resistance and short lifespan. For example, the application number 201610414333.8 discloses ...
