Description

Technical Field

[0001] The invention relates to the field of pearl cotton production, in particular to an EPE pearl cotton anti-slip process. Background Art

[0002] Pearl cotton is a soft foam material made of polyethylene foam. It has the characteristics of lightness, softness, sound insulation, shockproof and heat preservation. It is widely used in packaging, heat preservation and sound insulation fields.

[0003] When common pearl cotton is packaged, the product is protected during transportation by covering the outside of the product with pearl cotton. The product contacts the placement position through the surface of the pearl cotton. However, due to the low friction coefficient of the pearl cotton surface, its anti-slip performance is reduced. When the product shakes during transportation, the product is prone to sliding, which reduces the stability of the product and affects the safety of product transportation. Summary of the invention

After the pre-pressing treatment, the flattening equipment is used for flattening again, and then the flattened and shaped material is wound up by a winding machine to obtain the EPE pearl cotton coil.

[0013] Preferably, the silica aerogel in step S1 is obtained by grinding aerogel blocks. The silica aerogel has a large specific surface area and a high porosity, and is used to thicken, thixotropically and reinforce the molten raw materials.
