Embodiment Construction

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0021] refer to figure 1 , Vegetable oil polyether production sponge process, including raw material supply section 1, mixing section 2, foaming section 3, first extract and synthesize polyether polyol from vegetable oil raw material, obtain vegetable oil polyether polyol. The raw material components of the raw material supply section 1 include a polyol component and an isocyanate component. The polyol component is a combined polyol component formed by mixing vegetable oil polyether polyol, chain extender, foaming agent, catalyst and foam stabilizer, and the isocyanate component includes isocyanate. The raw material components are respectively input into the working storage tank, and the temperature control system regulates the temperature of the ...

Abstract

The invention relates to the field of sponge products, and specially, relates to a technology for producing sponge from a plant oil polyether. The technology comprises a raw material supply process section, a mixing process section and a foaming process section. The technology is characterized in that through extraction and synthesis, a plant oil polyether polyol is prepared from plant oil raw materials; raw materials adopted by the raw material supply process section comprise a polyol component and an isocyanate component; the polyol component comprises the plant oil polyether polyol, a chain extender, a foaming agent, a catalyst and a foam stabilizer; the isocyanate component comprises isocyanate; the raw materials are respectively input into a work storage tank; and a work storage tank temperature is controlled in a range of 20 to 25 DEG C by a temperature control system, wherein the temperature error is less than 1DEG C. The technology has the advantages that a plant oil polyether replaces a traditional petroleum polyether to be utilized for production of sponge (comprising common sponge and slow-rebound sponge), and thus waste sponge degradation is realized; environmental pollution is reduced; and environmental protection and sustainable development can be promoted.

Description

technical field [0001] The invention relates to the field of sponge products, in particular to a sponge technology. Background technique [0002] Sponge products have gradually become popular in people's lives, including seats, sofas, mattresses and other household items made of sponge. In addition to the household items made of sponges, people also use sponges as cleaning utensils, such as cleaning household with sponge products, cleaning dishes with sponge products, bathing with sponge products, etc. [0003] Polyether polyol is the main raw material for the production of polyurethane sponge. The polyether polyol generally used in the production of polyurethane sponge is usually petroleum polyether polyol. However, the polyurethane made of petroleum polyether polyol has high stability and is naturally It is difficult to decompose in the state; making it non-degradable is not conducive to environmental protection and sustainable development. At the same time, as petrochem...
