Description
Technical Field
The invention relates to the technical field of sponge foaming, in particular to a high-performance clean sponge.
Background
With the gradual increase of national economy and the gradual improvement of the living standard of people, the requirements of consumers on furniture products are gradually improved, and the requirements of high-performance sponge products are promoted to a certain extent. Sponge as a porous organic polymer has strong combustibility and has great potential safety hazard.
The traditional method for improving the flame retardant property of the sponge is to add a flame retardant mixture formed by combining halogen-containing polymers or halogen-containing flame retardants into the formula. This method has many problems, and the added flame retardant reduces the mechanical properties of the sponge product. With the time, the flame retardant is likely to migrate and be separated out of the product, so that the stability and the flame retardance are influenced; halogen-containing flame retardants release smoke and toxic gases when the article is burned. Another method for improving flame retardance is to introduce flame retardant elements and groups into a molecular structure, but the conventional method is not ideal in flame retardance effect, or the preparation method is complex and has high cost and great difficulty in industrial production.
The existing flame-retardant sponge is fragile and easy to break in use, which affects the quality of articles made of the flame-retardant sponge and relatively reduces the service life of the flame-retardant sponge product. But has no obvious breakthrough for low-density high-quality high-resilience products with higher requirements on the aspects of operation tolerance, dimensional stability, elasticity and the like.

In the course of further investigations it was found that when the polyether polyol having a hydroxyl value of 50-60mg KOH/g, the mass ratio of the first polymer polyol having a hydroxyl value of 18-30mg KOH/g to the second polymer polyol having a hydroxyl value of 32-48mg KOH/g was 1: (0.066-0.08): (0.166-0.2), the graphite can be tightly combined with other raw materials, so that the dispersibility of graphite is improved, and the volatility of organic matters of the sponge is reduced.
Graphite (II)
In the invention, the graphite is an allotrope of carbon, is a gray black opaque solid, has a density of 2.25 g per cubic centimeter, a melting point of 3652 ℃ and a boiling point of 4827 ℃.

Preferably, the mass ratio of the polyether polyol to the expanded graphite is 1: 0.028.
the Expanded Graphite (EG for short) is a loose and porous vermicular substance obtained by intercalating, washing, drying and high-temperature expanding natural Graphite flakes. EG has excellent properties such as cold and heat resistance, corrosion resistance, self-lubrication, etc. of natural graphite itself, and also has characteristics such as softness, compression resilience, adsorptivity, ecological environment compatibility, biocompatibility, radiation resistance, etc. which natural graphite does not have.
The inventor adopts the expanded graphite to improve the flame retardance of the sponge, and in the research process, the inventor finds that the sponge is subjected to slag removal and the mechanical property of the sponge is reduced due to the fact that the expanded graphite is added too much, and the flame retardance of the sponge is poor when the expanded graphite is added too little. In the process of further research, the inventor finds that when the mass ratio of the polyether polyol to the expanded graphite is 1: (0.016-0.04), the particle size of the expanded graphite is 0.5-1.5mm, and the sponge has excellent mechanical properties and flame retardant properties. The reason the inventor guesses may be that the expanded graphite has a worm-like structure, is porous and curved, has enlarged surface area and improved surface energy, and under the combined action of polyether polyol with 50-60mg KOH/g, first polymer polyol with a hydroxyl value of 18-30mg KOH/g and second polymer polyol with a hydroxyl value of 32-48mg KOH/g, the expanded graphite can be embedded, so that the dispersibility of the expanded graphite is improved, the softness, resilience and plasticity of the sponge are increased, the high carbon environment of the sponge is ensured, and the acarid resistance, antibacterial property and flame resistance of the sponge are improved.

Preferably, the amine catalyst is 1,3, 5-tris (dimethylaminopropyl) -hexahydrotriazine (CAS number 15875-13-5).
In a preferred embodiment, the tin catalyst is selected from one or more of dibutyltin dilaurate, stannous octoate, dibutyltin diacetate.
Preferably, the tin catalyst is stannous octoate (CAS number 301-10-0).
In a preferred embodiment, the catalyst is a mixture of 1,3, 5-tris (dimethylaminopropyl) -hexahydrotriazine and stannous octoate, and the mass ratio of the two is 21: 19.
surface active agent

the organic silicon oil surfactant is adopted by the inventor to reduce the surface tension of the mixture, ensure the stability of the foam through the surface tension in the foaming process, and improve the strength and the porous size stability of the foam. When Mitigo silicone oil L-580 is further adopted, the mass ratio of the Mitigo silicone oil L-580 to the expanded graphite is 1: (1.2-2), the sponge will not discolor during use, the inventor guesses that the reason is probably that the good air permeability of the mezzanine silicone oil L-580 can avoid the burning of foam, and the mezzanine silicone oil L-580 can provide a wide operation range of tin catalyst, and can inhibit the sponge from being oxidized during use under the combined action of the tin catalyst and the expanded graphite.
