Degradable highly-elastic sponge and preparation technology thereof

Abstract

The invention relates to degradable highly-elastic sponge and a preparation technology thereof. The degradable highly-elastic sponge and the preparation technology thereof have the advantages that thedegradable highly-elastic sponge is made of green, natural and healthy materials according to the environment-friendly preparation technology, harmless to human bodies and capable of avoiding resource waste and environment pollution, and its mechanical properties including rebound resilience and compression set value are in compliance with the international standards; through adoption of recyclable pineapple fibers, resource waste is reduced and physical properties of low-density sponge with natural latex matrixes are improved to comply with the international standards; sodium alcohol ether sulphate and sodium lauryl sulfate which serve as foaming agents substitute for traditional pollutional ones to further avoid pollution; the high-performance low-density sponge with the excellent mechanical properties can be produced at a low preparation cost; the preparation technology is safe, simple and environment friendly.

Description

technical field [0001] The invention relates to the field of a sponge, in particular to a sponge containing healthy green natural ingredients, the production process is environmentally friendly, has no pollution to the environment, has no harm to the human body, can avoid waste of resources and environmental pollution, and has mechanical properties such as resilience and compression permanent deformation values ​​in line with International standard degradable high-elastic sponge and its preparation process. Background technique [0002] Sponge is a very common porous material with good water absorption, some of which have good elasticity, deformation recovery and other properties, and can be used to clean items or to produce some comfortable and soft seat cushions. [0003] Commonly used sponges are made from wood cellulose fibers or expanded plastic polymers. Alternatively, there are natural sponges made from spongy animals, and most natural sponges are used for body clean...

Problems solved by technology

[0006] In order to solve the high production cost of the above-mentioned high-density sponge, the poor mechanical properties of the low-density sponge cannot meet the standard of seat cushion sponge, and the pollution generated in the preparation process of the sponge is relatively large, the artificial high polymer is difficult to degrade, and the foaming agent is In order to solve the problems of harming people and polluting the environment during the soaking process, it provides a product containing healthy green natural ingredients, the production process is environmentally friendly, has no pollution to the environment, has no harm to the human body, can avoid resource waste and environmental pollution, and has resilience and permanent compression.
