Abstract
The invention discloses a soft polyurethane foaming plastic, which is prepared from the following ingredients in parts by weight: 40 to 50 parts of polyether, 30 to 35 parts of isocyanate, 1 to 1.2 parts of silicon oil, 0.15 to 0.2 part of stannous octoate, 0.09 to 0.1 part of triethylene diamine, 5 to 8 parts of dichloromethane, 8 to 12 parts of filling materials, 0.5 to 0.8 part of plasticizers and 1.5 to 3 parts of water. The existing soft polyurethane foaming plastic recipe is improved; all ingredients are mutually cooperated and matched, so that the polyurethane foaming plastic has the advantages of high density, high rebounding performance, high compression load, low cost and great application range.
Description
Technical field
The present invention relates to a kind of macromolecular material, more particularly, to a kind of flexible polyurethane foam.
Background technology
The global polyurethane foam market demand in 2015 up to 9.6 hundred million tons, on polyurethane foam market contain by the Asian-Pacific area
Huge growth potential, automobile, furniture industry become the frontier of the polyurethane foam market demand.Sponge is used as soft poly- ammonia
One branch of ester foamed plastic, has extensively in every field such as commercial production, science and techniques of defence, health care, daily life
Application.With premium properties such as density low, elastic recovery is good, sound-absorbing, ventilative, insulations.Soft polyurethane foam product accounts for polyurethane
The 80% of industry total flow, with industrial expansion, this ratio is also rising.
Sponge is to mix polyethers or polyester resin, cross-linking agent, foaming agent, catalyst and surfactant instead
A kind of block soft bubble of simultaneously molding is answered, then through the working procedure processing such as cutting, compound into variously-shaped product.Production technology is main
There is block soft bubble and mold soft two kinds of bubble, because the field that it is used is different, can all there is different wanting to density, soft or hard, resilience
Ask.Density is an important characterization parameter of sponge, affects the load-carrying properties and service life of sponge, even if having reached high
Load, the structural framework composition of low density products must be less than high density product, after certain use time, will
The a series of problem such as deform, and service life can not reach requirement.But current flexible polyurethane foam high density
Can not have both simultaneously with high resilience so that its application is subject to a definite limitation.
The content of the invention
The invention aims to provide a kind of while having high density, high resilience, high compression loads concurrently, and cost is more
Cheap flexible polyurethane foam.
To achieve these goals, the present invention is employed the following technical solutions：
A kind of flexible polyurethane foam, it is made up of the component of following weight portion：40~50 parts of polyethers, 30~35 parts
Isocyanates, 1~1.2 part of silicone oil, 0.15~0.2 part of stannous octoate, 0.09~0.1 part of triethylene diamine, 5~8 parts of dichloromethanes
Alkane, 8~12 parts of fillers, 0.5~0.8 part of plasticizer, 1.5~3 parts of water.The present invention matches somebody with somebody to existing flexible polyurethane foam
Fang Jinhang is improved, and polyethers and isocyanates are polyurethane foam plastics raw material, and silicone oil is dispersant and foam stabilizer, and octanoic acid is sub-
Stannum is catalyst, and triethylene diamine is initiator, especially increased filler, dichloromethane, filler plus membership greatly improve it is poly-
The density and load of urethane foam, but the addition of filler can cause that polyurethane foamed material texture is harder, and resilience is poor, because
Dichloromethane is added in this present invention, dichloromethane can produce many micro-bubbles, these bubbles can both make uniform filling
Dispersion avoids piling up, and affects the concordance of final products, while these bubbles can improve the opening of polyurethane foam, then coordinates
Plasticizer solves polyurethane foamed material texture after addition filler harder finally with the resilience of raising polyurethane foam plastics
And the problem that resilience is poor.The mutual coordinated of each component in flexible polyurethane foam of the present invention so that polyurethane foam
Foam plastics have high density, high resilience, high compression loads concurrently, and cost is more cheap, with larger range of application.
Preferably, described filler particle diameter is 800~1000 mesh.
Preferably, described filler is the one kind in Calcium Carbonate, calcium sulfate, calcium chloride, barium sulfate, brium carbonate, barium chloride
Or it is various.
Preferably, the plasticizer is dioctyl phthalate.
Therefore, the present invention has the advantages that：Existing flexible polyurethane foam formula is improved,
The mutual coordinated of each component so that polyurethane foam plastics has high density, high resilience, high compression loads concurrently, and cost is more
For cheap, with larger range of application.
