Description

A kind of leather surface layer slurry of anion polyurethane resin
Technical field
The invention belongs to automotive interior material technical fields, and in particular to a kind of leather surface layer of anion polyurethane resin Slurry.
Background technique
If woven fabric, PU are removed from office generally polyurethane is added in anion powder by anion poiyurethane skin material for automobile interiors It is processed in raw material, purifies air since anion has, eliminates the peculiar smell and pernicious gas in air, and alleviate tired Labor, the advantages that promoting the metabolism of human body, as exploitation it is narrow can be mainly used for aircraft etc. with the synthetic leather of releasing negative oxygen ion Confined space, such generation anion are conducive to the environment for improving small space, improve driver and passenger's sensory experience.So negative The dispersion of ion powder and dispersion stabilization directly affect the final mass and various performances of anion product, and be uniformly dispersed journey Degree is higher, and capability and performance is also better, while anionic additive cannot bring a negative impact production technology.
It is substantially all to use the materials such as tourmaline, Strange ice stone powder at present for the exploitation of the composite materials such as anion synthetic leather Material, is directly added into polyurethane synthetic system after being processed into superfine powder, and effect occurs to obtain anion.But this technique Presently, there are problems: the surface of tourmaline powder can be big, and the surface-active of ultra-fine negative ion powder particle is very high, individual particle It cannot be stabilized, often reunited and attracting each other, so that stable state can be formed by reducing its surface.And reunite Later, the deterioration that will lead to superfine powder performance is unfavorable for the embodiment of negative ion powder performance, it is easier to product quality occurs and ask Topic.Tourmaline powder differs greatly with high molecular polymer surface property in the application, so that it is less susceptible in non-polar polymer In it is evenly dispersed and be stabilized, if being directly filled in organic matter, certain performances decline of material is easily led to, to influence to answer The whole synthesis performance of condensation material.
Summary of the invention
In order to overcome drawbacks described above existing in the prior art, the present invention provides a kind of faces of anion polyurethane resin Layer slurry, the production system for Synthetic Leather.The anionic additive invented is tourmaline@13X points of core-shell structure Son sieve, the excellent characteristics as anionic additive derive from its material characteristics: shell is that 13X framework of molecular sieve has negative electricity Lotus, micropore can be with adsorbed water molecules, carbon dioxide, and the free electron for facilitating tourmaline generation is transmitted in air molecule, more Anion easy to form；Silicone hydroxyl, aluminium hydroxyl are contained in surface simultaneously, can react with polyurethane synthesis material TDI, in polyurethane After molecular sieve particle is added, polyurethane is continuous phase, and molecular sieve particle is dispersed in wherein, forms " sea-island " structure, In When material is cracked by external force, molecular sieve particle can prevent crackle from developing to a direction, and crackle is refined, and consume Energy has delayed fracture, thus improves the mechanical strength of material.Simultaneously because molecular sieve particle surface charge distribution is uneven, So that the hard segment crystal habit of polyurethane is changed, forms small and more hard section crystalline sheets, be dispersed in soft segment, it is this kind of thin Brilliant surface area is big, is connected with soft segment with chemical bond, is physical crosslinking it is also assumed that increasing and changes stress distribution.In addition The micropore of molecular sieve can adsorb carbon dioxide gas and moisture, subtract the microbubble hole in polyurethane/molecular sieve composite material It is few, improve polyurethane/tourmaline@13X molecular sieves compound material performance.Polyurethane face is added in above-mentioned anionic additive to apply In slurry, anion polyurethane resin surface layer slurry is made, is used for skin material for automobile interiors, skin material may be implemented Anion release.
The present invention is achieved through the following technical solutions:
A kind of leather surface layer slurry of anion polyurethane resin, is made of following components by mass fraction:
Waterborne polyurethane resin: 100 parts
Water: 20~40 parts
Water-based ink: 10~30 parts
Anionic additive: 3~5 parts.
Further, the anionic additive is the tourmaline@13X molecular sieve of core-shell structure.
Further, the tourmaline@13X molecular sieve the preparation method is as follows:
A, by mechanical shearing, tourmaline is made to 6-20 microns of partial size of powder A；
B, sodium metaaluminate, sodium hydroxide, sodium metasilicate, water are mixed according to following molar ratio, SiO2/Al2O3=3~5； Na2O/SiO2=1~1.5；H2O/Na2O=35~65；Sol B is obtained after mixing；
C, powders A is added in sol B, and mass ratio is A/B=3~5%, continues after mixing evenly, to be stored at room temperature 3~8h；
D, it is put into the stainless steel cauldron of polytetrafluoroethyllining lining, 5~14h is stood at 98 ± 2 DEG C；
E, product is washed with deionized, filters, dries, and obtains tourmaline@13X molecular sieves compound material.
Compared with prior art, advantages of the present invention is as follows:
With using conventional method, that is, the anion powder that machining is added is compared, the tourmaline that the present invention is added 13X molecular sieves compound material not will lead to the mechanical properties decrease of material as negative oxygen ion additive, to influence composite wood The whole synthesis performance of material；The present invention solves the compatibility issue of tourmaline powder and polyurethane system, is prepared for removing from office with negative Ion polyurethane resin surface layer slurry.
