Comparative example 1
A preparation method of elastic heating cloth comprises the following steps:
s1: preparing elastic heating cloth
(1) Preparation of gallium indium tin liquid alloy
Weighing and mixing metal raw materials according to the weight ratio of 65% to 25% to 10% of gallium, indium and tin, and stirring at 80 ℃ until no solid particles exist;
