Description
Technical field
It is the present invention relates to a kind of preparation method of high-molecular organic material, in particular to a kind of from the artificial leather table for growing lines
Finishing coat agent and preparation method thereof.
Background technique
In artificial leather synthetic leather production process, production lines is that wherein an extremely important process, tradition generate lines
Method, mainly have release paper method and embossing method.Release paper method needs release paper price to be used high and non-renewable；Embossing method
It is also expensive for needing embossing rod to be used, and tailor-made time-consuming.The product of two above method production has common problem
It is that lines dullness is stiff, lacks individuality.
Summary of the invention
The purpose of the present invention is to provide a kind of from the artificial leather surface coating agent and preparation method thereof for growing lines, has
Simple process, easy to use, the cost of material is low, and decorative pattern can control its form and size by certain way, can individually or with
Conventional method combination creates more decorative pattern styles for artificial leather, meets more individual demands, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the invention provides the following technical scheme: it is a kind of from the artificial leather surface covering for growing lines
Agent, including the ingredient matched comprising following weight percent: 5 ~ 25% film forming matter, 40 ~ 90% solvent, 5 ~ 25% filler and 1
~ 10% drop cohesive force auxiliary agent.
Further, film forming matter is polyurethane resin, nitrocellulose and polyacrylate resin etc., is selected one of
Or it is a variety of.
Further, solvent mostly uses DMF, TOL, MEK, EAC, IPA and water etc..
Further, filler uses machine filler and inorganic filler, such as SiO2、CaCO3, PP, PE micro mist etc..
Further, drop cohesive force auxiliary agent is low-molecular weight polymer, such as aldehyde ketone resin and low molecule PE wax.
The present invention provides another technical solution, a kind of preparation method of the artificial leather surface coating agent from growth lines, packet
Include following steps；
S1: it weighs in suitable solvent and resin investment reaction kettle, is stirred at 100r/min revolving speed and 60 DEG C to being completely dissolved；
S2: it weighs in suitable drop cohesive force auxiliary agent and solvent investment dispersion bucket, starts high speed disperser, control revolving speed 600r/
Min is added in the solution of step 1 after dispersing 10min,
S3: weighing suitable filler, is added in grinder, after being ground to particle diameter to 20um or less, is filtered with 400 mesh grenadines
Pigment, filtered filler weigh in the solution being fitted into step 1, continue to stir, revolving speed 200r/min, disperse 40min, add
Enter in the solution of step 2；
S4: step 2 and step 3 acquired solution are poured into the same reaction kettle equipped with blender and thermometer, are added suitable
The defoaming agent and film forming matter of amount are warming up to 50 degrees Celsius, and constant temperature stirs 1h.
Further, artificial leather needs are used in combination with ground, and ground is generally polyurethane, if other grounds, first
With polyurethane material bottoming, polyurethane material need to be selected soft, and 100% modulus is 80 or less.
Further, the coating weight on artificial leather is 30-150g/m2Cutter painting can be used, rod applies, and the modes such as spraying are handled.
The principle of the present invention is: coating product is coated on substrate surface, with the volatilization of solvent or moisture content, film forming matter
With contraction, when coating shrinkage stress is greater than film forming matter cohesive force, surface layer will be cracked, by control shrinkage stress and
The ratio of cohesive force, evaporation rate, ground and coating it is soft or hard than etc. conditions, will just obtain a series of decorative patterns of different shapes,
Such as star line, branch line, mountains and rivers river line, the product of the different lines of dry line of the earth etc..
The present invention generates decorative pattern with simplest method, do not need and save auxiliary material, release paper, embossing rod etc. at
This, decorative pattern is formed with growth mode, has natural beauty, and decorative pattern can control its form and size by certain way, can be single
It combines solely or with conventional method, creates more decorative pattern styles for artificial leather, meet more individual demands.
