Problems solved by technology

This substance is not provided by non-renewable resource petroleum. With the continuous decline of petroleum, the supply of this substance will become more and more scarce. In addition, because the extraction of polyether polyol from petroleum will cause environmental pollution, therefore, the use of this substance Sponge is made, which is not friendly to the environment

Abstract

The invention mainly discloses a biodegradable slow-recovery sponge, and in particular relates to the sponge comprising main materials which use palm oil polyalcohol components instead of components of partial petroleum byproducts so as to realize biodegradability and environmental protection. Furthermore, because the product adopts plant oil to replace partial petroleum byproducts, the sponge realizes that renewable energy is adopted to replace non-renewable energy, not only relieves the crisis of raw material shortage along with non-renewable energy shortage in the future, but also can reduce volatile smell of the sponge and maintain the nature flavor of the oil due to the characteristics of the plant oil self.

Description

technical field [0001] The invention relates to a sponge, in particular to a polyether polyol which uses vegetable oil polyol as a raw material to replace part of petroleum by-products and realizes environmental protection. Background technique [0002] The main components of sponges currently on the market are polyether polyols, which are petroleum by-products. This substance is not provided by non-renewable resource petroleum. With the continuous decline of petroleum, the supply of this substance will become more and more scarce. In addition, because the extraction of polyether polyol from petroleum will cause environmental pollution, therefore, the use of this substance A sponge is produced, which is not friendly to the environment. Contents of the invention [0003] The main task of the present invention is to provide a palm oil polyol sponge, in particular to a polyether polyol that uses vegetable oil as a raw material to replace part of petroleum by-products to achi...
