Abstract
A kind of preparation method of modified polyurethane hydrophilic material, it is characterised in that：Include the following steps：(1) polyalcohol and isocyanates are prepared by mixing into urethane raw；(2) into urethane raw, addition water is put into polyurethane foaming machine and carries out foamable reaction, and operation temperature is 20 50 degrees Celsius, and adds polyurethane aqueous mill base, mixed foaming 1 10 minutes according to required color；(3) after being foamed into foam toast within 24 hours, operation temperature is 50 80 degrees Celsius；(4) thoroughly after drying, thickness as needed carries out cutting for sheet material.The invention has the advantages that：It saves labour turnover, and can be used for cotton pads, cushion etc., low dust, high comfortable advantage, high-tension, flexible, breathable pro-skin can be reached, better than traditional latex, tearing strength is high, and odorlessness and environmental protection are repeated and utilized, with antibacterial effect, it is water washed after be not easy it is mouldy, be not afraid of dirty, soil can be melted by being placed in for a long time in ground.
Description
Technical field
The present invention relates to polyurethane material technical fields, and in particular to a kind of preparation side of modified polyurethane hydrophilic material
Method.
Background technology
Foam is the material that plastic pellet foamed, and builds up foam, and foam has flexible, light-weight, quickly pressure-sensitive solid
Fixed, easy to use, bending freely, a series of features such as the ultra-thin, dependable performance of volume, foam currently on the market is latex mostly
It is made, it is odorous, it can be hardened when dry perishable, not environmentally, existing common foam cost is higher, and without cloth decoration, therefore needs
Other beautiful decorations are subject to appearance, Freehandhand-drawing high labor cost takes and draws risk height that is wrong or being undesirably worth, and answers
It is small with range.
Invention content
Technical problem to be solved by the invention is to provide a kind of preparation methods of modified polyurethane hydrophilic material, special
Sign is：Include the following steps：
(1) polyalcohol and isocyanates are prepared by mixing into urethane raw；
(2) into urethane raw, addition water is put into polyurethane foaming machine and carries out foamable reaction, operation temperature 20-50
Degree Celsius, and polyurethane aqueous mill base, mixed foaming 1-10 minutes are added according to required color；
(3) after being foamed into foam toast within 24 hours, operation temperature is 50-80 degrees Celsius；
(4) thoroughly after drying, thickness as needed carries out cutting for sheet material.
Preferably, the mixed foaming time is different by polyalcohol and isocyanates ratio, model size, reaction temperature
It influences.
Preferably, material can be put into mold after the step (4), by horizontal spreader bar compression moulding, then is led to
Hot pressing design drawing pre-designed in cycle machine hot pressing is crossed, operation temperature is 60-100 degrees Celsius.
The invention has the advantages that：Save labour turnover, and can be used for cotton pads, cushion etc., it can reach low
Dust, high comfortable advantage, high-tension, flexible, breathable pro-skin has moulding independence, diversity and comfort, better than tradition
Latex, tearing strength are high, and odorlessness and environmental protection are repeated and utilized, have antibacterial effect, it is water washed after be not easy it is mouldy, be not afraid of it is dirty
Dirt, soil can be melted by being placed in for a long time in ground.
Specific implementation mode
A kind of preparation method of modified polyurethane hydrophilic material, it is characterised in that：Include the following steps：
(1) polyalcohol and isocyanates are prepared by mixing into urethane raw；
(2) into urethane raw, addition water is put into polyurethane foaming machine and carries out foamable reaction, operation temperature 20-50
Degree Celsius, and polyurethane aqueous mill base, mixed foaming 1-10 minutes are added according to required color；
(3) after being foamed into foam toast within 24 hours, operation temperature is 50-80 degrees Celsius；
(4) thoroughly after drying, thickness as needed carries out cutting for sheet material.
The mixed foaming time by polyalcohol and isocyanates ratio, model size, reaction temperature is different is influenced.
Embodiment one
Material is cut to required thickness (1-3 centimeters), and is put into mold (such as droplet-shaped cutting die or the knife of other shapes
Mould) in, by horizontal spreader bar compression moulding, then pass through hot pressing design drawing pre-designed in cycle machine hot pressing, operation
Temperature is 60-100 degrees Celsius, carries out natural cooling after pattern forming, you can with unlike material pack according to party in request close
Envelope, that is, be made a kind of modified polyurethane hydrophily cotton pads, face be printed directly on after coating hydrop iotaiilic sponge with body paint
Upper Ke Chong Complex are used and figure is very consistent, can be reduced the makeup time and be kept identical integrity degree, even if the person that is bad at colored drawing
Also beautiful figure can be printed off with this mode, such as individual can be light when fancy ball or role playing and each red-letter day dress up
Pine is presented on the face, hydrophilic cotton pads odorlessness and easy cleaning, meets water and becomes larger, all soft pro-skin of dry and wet and personal operable, then
The risk looked for people's colored drawing or do not drawn well is needed without worry.
Embodiment two
Material is cut to required thickness (3-8 centimeters), later according to customer requirement make a return journey carry out beauty above tune
It is whole or transfer to its appearance of client's designed, designed, that is, be made a kind of hydrophily cushion, odorlessness, can often clean, be not afraid of it is dirty
The characteristics such as dirt are all the effects that present cushion is extremely difficult to, and for many easily allergy people, dust is prodigious injury,
And this product can reach low dust, high comfortable advantage；High-tension, flexible, breathable pro-skin, high degree of dispersion spinal compression, rapidly
Alleviate lumbar vertebrae fatigue.
