Abstract
The present invention discloses polyurethane artificial leather including the following raw materials: polyurethane particles, graphene, a lubricant, a foaming agent, talc powder and a pigment. A technological process of the polyurethane artificial leather comprises the following steps: proportionally weighing the raw materials to put into a stirrer for stirring, then sending into an internal mixer, heating for plastication, gelling and homogenizing, then filtering, after the filtration, defoaming in a vacuum defoaming machine for standby use, calendering with a calendar to obtain a fabric, using a laminating machine for laminating base cloth and the fabric under heating and pressurization, using a foaming machine to decompose and foam a foaming agent at high temperature; sending into a curing room for curing for 48 hours or more, taking out from the curing room, cooling sufficiently, packing into rolls to obtain a finished product. By adding of the graphene, the strength and wear resistance of the artificial leather are improved, the service life of the polyurethane artificial leather is effectively extended, the polyurethane artificial leather does not contain harmful toxic organic solvents, and environmental pollution caused by industrial production can be significantly reduced.
Description
Technical field
The invention belongs to polyurethane artificial leather technical field, specifically, relate to a kind of polyurethane artificial leather and process thereof。

Polyurethane resin application in synthetic leather is mainly reflected in multiple fields such as clothing, case and bag, footwear, furniture, automobile。
Although the development of polyurethane artificial leather has had the history of decades, but in the face of improving constantly of the market demand, polyurethanes technology is had higher requirement, such as, higher field is required for some physical property, as the fields such as footwear are higher for the requirement of the physical property such as hydrolysis, extent of exfoliation, this just requires that polyurethane has corresponding character。The many polyurethane occurred on market there is also a certain distance in hydrolysis, peel resistant strength etc.。
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide a kind of polyurethane artificial leather and process thereof, hydrolysis, peel resistant strength significantly improve, effectively extend the service life of polyurethane artificial leather, and without harmful poisonous organic solvent, significantly reduce the environmental pollution that industrialized production is brought。
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions:
A kind of polyurethane artificial leather, including following raw material: polyurethane particles, Graphene, lubricant, foaming agent, Pulvis Talci and colorant。
Further, according to percetage by weight, described polyurethane particles 80-90%, Graphene 1-3%, lubricant 2-5%, foaming agent 1-3%, Pulvis Talci 4-6% and colorant 1-3%。
Further, according to percetage by weight, described polyurethane particles 85%, Graphene 2%, lubricant 2%, foaming agent 3%, Pulvis Talci 6% and colorant 2%。
Further, be additionally added described polyurethane particles weight 0.5～2.0% preparing spherical SiO 2。
Further, the polyacrylate of the 10%-20% of described polyurethane particles weight it is additionally added。
Further, described lubricant is phthalic acid ester。
Further, described foaming agent is azodiisobutyronitrile。
Further, described colorant is inorganic pigment。
Further, described inorganic pigment is titanium white, medium chrome yellow, iron oxide yellow or iron oxide red。
The process of a kind of polyurethane artificial leather, comprises the following steps:
1) weigh described raw material by described proportioning and enter blender stirring；
2) send into banbury, carry out intensification and plasticate；
3) filter after carrying out gel and homogenizing, standby through vacuum defoamation machine deaeration after filtration；
4) fabric is obtained by calender calendering；
5) base fabric and fabric are added pressure laminating in heating by make-up machine；
6) foaming machine makes foaming agent at high temperature reduce foaming；
7) send into curing chamber ripening more than 48 hours, take out sufficiently cool rear bundling from curing chamber and be packaged to be finished product。
Compared with prior art, the invention has the beneficial effects as follows:
A kind of polyurethane artificial leather of the present invention and process thereof, by adding Graphene, improve intensity and the wearability of artificial leather, effectively extend the service life of polyurethane artificial leather, and without harmful poisonous organic solvent, significantly reduce the environmental pollution that industrialized production is brought。
