Sponge synthesized from bio-based isocyanate and mattress prepared from sponge

Abstract

The invention provides a sponge synthesized from bio-based isocyanate and a mattress prepared from the sponge, and relates to the technical field of thick mattresses and thin mattresses. According to the sponge synthesized from bio-based isocyanate, the bio-based isocyanate is bio-based toluene diisocynate (TDI), and the sponge is prepared from the following raw materials in parts by weight: 100 parts of polyol, 1.45- 4.7 parts of water, 0-12 parts of dichloromethane, 0.3-1.5 parts of a silicone surfactant, 0.1-0.33 parts of an amine catalyst, 0.02-0.39 parts of stannous octoate and 39.89-61.84 parts of the bio-based TDI. The sponge is synthesized from bio-based toluene diisocynate and polyol, the bio-based toluene diisocynate is synthesized from bio-based toluene, nitric acid, hydrogen and carbon monoxide as raw materials, and the bio-based toluene diisocynate is used to replace traditional toxic petroleum-based isocyanate, so that the dependence of sponge production on petroleum can be reduced, and meanwhile, carbon emission and environmental pollution caused by use of petroleum are reduced.

Description

technical field [0001] The invention relates to the technical field of mattresses, in particular to a sponge synthesized from bio-based toluene diisocyanate and a mattress prepared from the sponge. Background technique [0002] Mattress is an item between the human body and the bed to ensure consumers get a healthy and comfortable sleep. Mattresses are made of various materials, and mattresses made of different materials can bring different sleep effects to people. [0003] At present, there are only sponges synthesized from bio-based polyols and petroleum-based isocyanate on the market. Most of the current production methods rely on toxic petroleum-based isocyanate. The residual toxic petroleum-based impurities in the finished product will cause adverse health reactions after inhalation, such as irritation to the skin, eyes and throat. , leading to asthma and other serious lung problems, while the use of petroleum-based isocyanates consumes non-renewable petroleum, and exce...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a sponge synthesized from bio-based toluene diisocyanate and a mattress prepared from the sponge, which solves the problem that only bio-based polyols and petroleum-based isocyanate are synthesized on the market. Its residual toxic petroleum-based impurities will cause adverse health reactions after inhalation, and at the same time, excessive consumption of non-renewable petroleum will cause environmental pollution.
