Embodiment 1
[0022] The detailed technical scheme of the present invention is specifically described below in conjunction with embodiment:
[0023] A quick preparation method of a light-duty sponge body, comprising: (1) putting foam plastics of various shapes and sizes into a shredder to shred, and controlling the mesh diameter of the filter screen at the outlet of the shredder to be about 1 cm. ②According to the following proportions by mass: 70% of polyether polyol, 29% of tolylene diisocyanate, and 1.0% of stannous octoate, fully mixed and stirred evenly to prepare the adhesive. ③ Take 78% of the chopped foam plastics and 22% of the adhesive according to the mass percentage and put them into a mixer to fully stir and mix them, then put them into a special container for extrusion molding, and control the extrusion demoulding time to 4 hours. After demoulding, a lightweight sponge with good elasticity, softness, moderate durability is obtained.
Embodiment 2
[0025] A quick preparation method of a light-duty sponge body, ① put foam plastics with different shapes and larger fragments into a shredder to shred, and control the mesh diameter of the filter screen at the discharge port of the shredder to be about 5 centimeters. ②According to the following proportions by mass percentage: 80% polyether polyol, 19.5% tolylene diisocyanate, 0.5% stannous octoate, fully mixed and stirred uniformly in sequence to prepare the adhesive. ③ Take 93% of the chopped foam plastics and 7% of the adhesive according to the mass percentage and put them into a mixer to stir and mix them, then put them into a special container for extrusion molding, and control the extrusion demoulding time to 6 hours. After demoulding, a lightweight sponge with good elasticity, softness, moderate durability is obtained.
