Abstract

The invention relates to a production technology of flame-retardant cotton. The formula comprises the following components in percentage by weight: 45-55% of polyether polyol; 4-10% of FR-V6 flame retardant; 12-20% of toluene diisocyanate; 0-5% of dichloromethane; 0.25-0.5% of silicone; 0.5 to 1.5 percent of triethylene diamine; 8-14% of stannous octoate; 12 to 18 percent of water. The sponge has the advantages of combustion prevention, sound and heat insulation, good elasticity, low smoke, no toxicity and the like, can replace common sponge, is applied to the fields of airplanes, ships, trains and automobiles, and can be made into a mattress for guest rooms of hotels.

Description

A kind of flame-proof cotton

Technical field:

The present invention relates to a kind of production technology of flame-retardant sponge.

Background technology:

Sponge is widely used in aircraft, steamer, train, automobile and the daily goods, but the very easily burning in air of common sponge, and when burning produce a large amount of obnoxious flavour and flue dust, serious threat the safety of people's lives and properties.

Summary of the invention:

The objective of the invention is to overcome the shortcoming of common sponge, provide a kind of and can stop the incendiary sponge.

The present invention, its formulation weight per-cent is:

Polyether glycol 45-55%;

FR-V6 fire retardant 4-10%;

Tolylene diisocyanate 12-20%;

Methylene dichloride 0-5%;

Silicone 0.25-0.5%;

Triethylene diamine 0.5-1.5%;

Stannous octoate 8-14%;

Water 12-18%.

The present invention forms by efficient composite structure, synthetic chemistry reaction.Have advantages such as the burning of prevention, sound-insulating and heat-insulating, good springiness, low smog, nontoxicity, every technical indicator reaches the advanced level of international like product.Can replace common sponge, be applied to aircraft, steamer, train, automotive field, also can be made into mattress and be used for hotel guest-room.

Embodiment:

Polyether glycol 50kg, FR-V6 fire retardant 5kg, tolylene diisocyanate 14kg, methylene dichloride 1.5kg, stannous octoate 12kg and water 16kg are mixed stirring, make its reaction, when temperature rises to 70-130 ℃, add silicone 0.5kg and triethylene diamine 1.0kg again, through adjustment.

The described FR-V6 fire retardant of present embodiment, the product that can select for use Dongguan Bang Ni company or auxiliary reagent factory, Chunan, Zhejiang Province to provide.
