Description
Technical field
The present invention relates to a kind of teaching head filling environment-protecting polyurethane semihard foam material and preparation method thereof, belong to poly- ammonia
Lipase absobed technical field.
Background technology
Teaching head refers to teach for the model of cosmetology and teaching made of Se Fa and rubber and inside stuffing
Head, is a kind of hair dressing and beauty training aid.Teaching head entered China before and after 1980 by foreign trade, was mainly used at that time
Mouthful.Now with the development of the country of China hairdressing and beauty industry, teaching head is needed as a kind of important teaching aid of cosmetology training
The amount of asking surges, and has formd a huge market.Filler is full of in teaching head head cavity, filler generally uses foamed glue
Or air.Polyurethane foam plastics has excellent physical mechanics, acoustics, electricity and chemical-resistance, and the density of material
Size and soft or hard degree can change with the difference of raw material and formula, convenient plus molding construction, better than other plastics
Kind, so as to be widely used in the making of teaching head filler.
The polyurethane material that in the market is applied to the filling of teaching head cavity is mostly polyurethane rigid foam plastic, due to poly- ammonia
Ester rigid foam material can not return to original shape after deforming upon, and feel is poor, so in the market starts with poly- ammonia
Ester semihard foam material substitutes rigid foam material；Now, the polyurethane semihard foam material applied to the filling of teaching head cavity is due to polyethers
Polyalcohol, the selection of catalyst are improper, and there are surface irregularity particularly face and the matter such as brain rear portion is swollen, overall shrinkage is big
Defect is measured, and the foaming agent that component A uses is generally physical blowing agent, and physical blowing agent all has atmospheric ozone layer destruction to make
With will progressively be eliminated.
At present, the polyurethane semihard foam material increase intensity of in the market is mainly polynary by using common or high activity polyether
Alcohol is parent, carries out a step copolymerization or two step copolyreaction generation polymer polyatomic alcohol with vinyl monomer compound, this birdss of the same feather flock together
Compound polyalcohol cost is higher, limits its application.
The content of the invention
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of teaching head half hard bubble material of environment-protecting polyurethane
Material, has a good toughness, impact resistance, the advantages of can restoring to the original state after stress deformation, solves the mass defect in filling process,
Obtained teaching head good appearance, meets demonstration lesson requirement.
Meanwhile the present invention also provides its preparation method, manufacturing cost is reduced, environmentally protective, scientific and reasonable, operation letter
It is single.
Teaching head of the present invention environment-protecting polyurethane semihard foam material, is made of component A and B component, with quality
Percentage meter；
Component A：
B component：
Polymeric diphenylmethane diisocyanate；Wherein, polyether polyol A is 3 degrees of functionality, number-average molecular weight 3000-
6000 propylene oxide, ethylene oxide copolyether polyalcohol, and epoxy ethane Han Liang≤10wt.%；Polyether polyol B is 3
Degree of functionality, the propylene oxide polyether polyalcohol of number-average molecular weight 500-3000；Polyether polyol C is number-average molecular weight 250-550
Ethylenediamine based polyether polyol.
The solid enhancement agent is the one or more in precipitated calcium carbonate, powdered whiting or melamine.
The foam stabiliser is organosilicone surfactants；It is preferred that the U.S. steps figure L-580.
The water is deionized water.
The catalyst is dimethylaminoethoxyethanol, trimethyl hydroxyethylammonium ethylenediamine, double (dimethylaminoethyls)
One or more in ether or triethylene diamine.
The preparation method of teaching head filling environment-protecting polyurethane semihard foam material of the present invention, including following step
Suddenly：
1) prepared by component A
The polyether polyol A of proportional quantity, polyether polyol B, polyether polyol C and solid enhancement agent are put into mixing successively
Stirred evenly in kettle, then add foam stabiliser, water and catalyst, stir evenly；
2) prepared by B component
It is spare to weigh polymeric diphenylmethane diisocyanate；
3) in use, by component A and B component in mass ratio 1：0.7-1.5 is mixed, foaming.
Compared with prior art, the present invention has the advantages that：
Two component good fluidity of 1.A, B, pressure is low in foaming process, can preferably keep the appearance of teaching head, surface
No concave-convex injustice phenomenon, appearance ungauged regions metaboly in long-term placement process；
2. semihard foam material good toughness made from, impact resistance, can restore to the original state, it is suitable to select after stress deformation occurs
Solid enhancement agent, not only reduces production cost, also acts as certain fire retardation；
3. material therefor raw material is liquid, convenient transportation, storage stability are good；
4. use raw material not contain volatile solvent, it is pollution-free, any toxic gas is not produced, it is environmentally protective, to people
Body is harmless；
5. preparation process described in carries out at normal temperatures, and reaction speed is adjustable, and expansion density is adjustable, has not only saved the energy but also has subtracted
Few powering device and cumbersome operation, it is easy to operate, it is easy to use, it is scientific and reasonable.
