Description
Technical field
The invention belongs to imitative in skin manufacture technology field, be specifically related to a kind of make imitative in skin time used impregnation treatment fluid.
Background technology
In imitative skin its not only rich color, intensity high, be not easy damage, and there is toughness wear-resisting, higher preferably and TENSILE STRENGTH, in decreasing pollution, animal protection, ecological protection etc., play positive role simultaneously.Thus be widely used in leather shoes inside with rear cover, shoe-pad, leather trunk, handbag, leather wallet inside, belt interlayer, baseball glove and rolling, sport footwear packet header and heel leather, the base fabric being used in PU and PVC etc.In the prior art, in imitative, the preparation technology of skin is: fiber-manufactures nonwoven fabric-nonwoven fabric impregnation process-post processing (solidify, wash, extract out, drying etc.).In impregnation treatment process, directly have influence on the hard and soft of end product containing immersion liquid, feel is very important.Existing is generally all add some auxiliary agents to process with polyurethane resin, but like this process obtain imitative in skin or softness, good hand touch, but poor rigidity, or rigidity is too strong, feel is hardened.Particularly polyurethane resin needs the organic solvents such as toluene to process, unfriendly to environment.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of impregnation treatment fluid, nonwoven fabric after this treatment fluid process obtained imitative in skin, not only wear-resisting not yielding, various colors, almost close to the texture of corium, and soft, especially adopt water as solvent, very friendly to environment.
The present invention is achieved through the following technical solutions:
A kind of impregnation treatment fluid, comprises the following raw material according to listed as parts by weight:
Preferably, described aqueous, environmental protective glue is NBR aqueous, environmental protective glue; Preferable ph is 7.8 ~ 8.8, and viscosity is the aqueous polyurethane dispersion of 40 ~ 300mPa.s25 DEG C.
Preferably, 100% film number of the dry film of described aqueous polyurethane dispersion is 2.5 ~ 3.0MPa, and 300% film number is 5.1MPa, and tensile strength is 25.0 ~ 30MPa, and fracture elongation is 600 ~ 700%.
This aqueous polyurethane is basic medium with water, not only have do not fire, smell is little, free from environmental pollution, the energy-conservation and operation advantage such as easy to process, and soft durometer performance is adjustable, also has low temperature resistant, pliability simultaneously and drinks the advantages such as caking ability is large well.The HydranHW-311 of large Japanese ink company of preferred Japan.Not containing NCO group in current most of Aqueous Polyurethane Adhesives, thus mainly fixed line is carried out by intra-molecular polarity group generation cohesive force and adhesion, and solvent-borne type or non-solvent single-component and two-component polyurethane adhesive thereof stick the reaction that agent can make full use of NCO, increase adhesive property in adhesive solidification process.Containing the group such as carboxyl, hydroxyl in aqueous polyurethane in the present invention, can participate in reaction under suitable condition, be that adhesive produces gluing.
Preferably, defoamer is GPE50 type defoamer or dimethicone.Wherein, the ethyleneoxide addition amount of polypropylene glycol link ends is 50%, this defoamer hydrophily is better, easily sprawl in foaming media, solubility is also comparatively large, with NBR aqueous, environmental protective glue energy and other auxiliary agents composite well, defoaming activity is held time length, defoaming capacity is strong, effective in mixed liquor.
Preferably, described stabilizing agent is composition metal soap stabilizing agent.Because it has lubricity concurrently, the stability of colloid can be increased, reaction of slowing down, keep chemical balance, reduce surface tension, prevent light, thermal decomposition or oxidation Decomposition.More preferably calcium/zinc composite stabilizer.Its by calcium salt, zinc salt, lubricant, antioxidant etc. for key component adopts special combination process and synthesizing.It not only can replace the poisonous stabilizing agents such as plumbous cadmium salt class and organic tin, and there is goodish heat endurance, photostability and the transparency and tinting strength, tinting power, while the artificial leather environmental protection that the present invention is obtained, add different pigment and obtain coloury product.Wherein, pigment is this area common pigments, just repeats no more herein.
Preferably, described vulcanizing agent is penylene BMI between N, N'-.It can prevent recovery, improves heat resistance, reduces heat-dissipating, ageing-resistant, improves rubber and cord fabric thread bonding force and vulcanizate modulus.
In order to improve the fluency in the performance of final products and manufacture process, can also add some auxiliary curing agents, such as antiscorching agent, calcium hydroxide, maleimide, consumption is 2-4phr.They can not only significantly improve association performance, improve heat resistance, be applicable to high temperature vulcanized system, reduce compression set fairly obvious, the consumption of oxide can also be reduced over, prevent the incipient scorch of sizing material in process from can improve the scorching quality of elastomeric compound significantly, be applicable to southern high-temperature and add use season.
Preferably, described surfactant is the reactive Water-borne Polyurethane Surfactants with acetoacetic acid group.This activating agent is by polyethylene glycol, different Fo Er copper vulcabond and 2,2,6-trimethyl-4H-1, and 3-diox-4-copper is main raw material synthesis.This surfactant, except having excellent surface-activity, also can be polymerized with the monomer in system and put sheep out to pasture, make film have good corrosion-resistant, chemical-resistant.Surfactant contains parents' molecule of hydrophilic several days and hydrophobic several days, greatly can not only reduce the interfacial tension of solution surface or liquid level, changes the interface state of system, thus the effects such as generation is wetting, infiltration, emulsification, froth breaking, solubilising.
Bag of the present invention adopts specific aqueous, environmental protective glue to be equipped with fixing defoamer, stabilizing agent, vulcanizing agent, surfactant, dispersant and pigment, and is solvent with water.Nonwoven fabric is through conventional processing method, in this impregnation treatment fluid after process, obtain skin in imitating, the performance of its each side is all close to the physical and chemical performance of corium, not only rich color does not fade, feel is fine and smooth soft, and have higher mechanical strength wear-resisting, have certain elasticity and plasticity, not yielding, be easy to maintenance, also there is heat-resisting wet good stability, corrosion-resistant, the excellent ventilative advantage such as (vapour), moisture absorption (sweat), hydrofuge performance simultaneously; Especially adopt water as solvent, very friendly to environment.
