Abstract

The invention relates to the technical field of composite materials, in particular to a composite material of silicone rubber and reticulated polyurethane, a preparation method and application. The composite material comprises soft reticulated polyurethane with material meridians and collaterals and silicone rubber covering the surfaces of the material meridians and collaterals of the soft reticulated polyurethane, and the silicone rubber completely wraps the material meridians and collaterals. The composite material is a home textile elastic material with good resilience and has good air permeability, washing performance and weather resistance, and the defects that existing home textile resilience materials such as pillow inners and mattress inner mats cannot be washed with water, are noteasy to clean thoroughly and are prone to breeding bacteria are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material of silicone rubber and reticular polyurethane, a preparation method and an application thereof. Background technique [0002] At present, rebound home textile materials on the market, such as pillow cores, mattress pad materials, etc., no matter what kind of material they are, cannot have both breathable and water-washable properties. Commonly used pillow materials include polyurethane, latex, cassia seeds, etc. During the use of these materials, the human body will sweat and soak into the pillow material, which will cause mold and odor in the pillow core. Washing or boiling in water cannot thoroughly clean the pillow or mattress inner pad, and cannot completely solve the problem of pillow or mattress odor and mite removal. [0003] Although the polyurethane mesh material has air permeability and washable properties, the pillows produced with pur...
