The invention belongs to the technical field of imitation lining leather making, and concretely relates to an impregnation adhesive used in the making process of imitation lining leather. The impregnation adhesive comprises, by weight, 0.5-5 parts of butadiene-styrene aqueous rubber, 0.1-0.5 parts of an antifoaming agent, 0.1-0.5 parts of a stabilizer, 0.3-0.6 parts of a vulcanizing agent, 0.3-0.6 parts of a dispersant, 1-10 parts of a pigment and 185-195 parts of water. The specific aqueous environmentally-friendly adhesive is adopted to cooperate with the antifoaming agent, the stabilizer, the vulcanizing agent, the surfactant, the dispersant and the pigment, and water is used as a solvent and is mixed with above raw materials to prepare the liquid. A nonwoven fabric is treated by the impregnation adhesive to make the imitation lining leather, and the imitation lining leather has the advantages of real leather performance approaching performances, wear resistance, non-deformability, abundant color, no color fading, soft handle, and environmental protection.
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 containing impregnation.
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 impregnation, 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 one containing impregnation, 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 containing impregnation, comprise the following raw material according to listed as parts by weight:
Preferably, described butylbenzene water-base cement is the aqueous copolymers solution that butadiene and propylene are fine.Because its performance is close to natural rubber, be the maximum general purpose synthetic rubber of current production rate, be characterized in ABRASION RESISTANCE, ageing-resistant and heat resistance exceedes natural rubber, also comparatively natural rubber is even for quality.But its elasticity is lower, resistance toly subdues, tear resistance is poor; Poor processability, particularly tack are poor, green strength is low.The present invention is equipped with defoamer, stabilizing agent, vulcanizing agent and dispersant, can improve its shortcoming.
Preferably, styrene 38%, ethene 24%, ML1+480, extend oil TDAE, extend oil 37.5phr, Tg-29 DEG C is contained in described butylbenzene water-base cement.Preferred solution polymerized sbr of the present invention, it is butadiene and styrene monomer take butyl lithium as catalyst, combined polymerization in non-polar solven and random, the performances such as wear-resisting, flexure, resilience, heat-dissipating are good, extrude after-contraction little, be suitable for especially making light color or transparent article, in the present invention, the product that different colours made by pigment can be added, simultaneously color fast.Through scrubbing the tests such as heat, do not fade for a long time.More preferably German bright Sheng (Bayer) BunaVSL2438-2HM, has good antireversion energy.The low temperature flexibility of solution polymerized butadiene styrene rubber, resilience and ABRASION RESISTANCE.Tradition is used to the tire tread manufacturing summer and winter climate, but in the present invention, is equipped with other auxiliary agents, by controlling its Tg and combined polymerization section has carried out modification to its performance, the final products of obtained flexible relative.
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 has goodish heat endurance, photostability and the transparency and tinting strength, tinting power, make the present invention obtain imitative in while skin, 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, after this is containing process in impregnation, 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.
