Abstract
The invention relates to a water-based polyurethane emulsion compounded colored coating art canvas and a manufacturing technique, in particular to a canvas for painting artist and hobbies to paint, which belongs to the technical field of painting articles. And the process for manufacturing comprises getting hydroxypropyl cellulose to swell, heat up, stir and dissolve with half purified water of the total amount, and mixing and evenly stirring water-based polyurethane emulsion, styrene monomer- acrylate copolymer emulsion, graining paste, glycerin, alcohol and sodium benzoate, getting lithopone powder and calcium carbonate to mix with the upper glue solution after wetting with the residual water of the total purified water, evenly stirring to be coating slurry in normal temperature, and then applying coating slurry on primary backing, drying and baking to be end products. The service performance of the art canvas of the invention is greatly improved, since aqueous polyurethane emulsion(APU) is utilized in the formula, therefore the thermoplasticity polyurethane emulsion has the advantages of easy filming, low temperature resistance, excellent elasticity, flexibility and the like.
Description
Technical field
The present invention relates to a kind of water polyurethane latex composite compounding color coat art canvas and production technology thereof, specifically be used for graphics art man and fan's drawing; Be applicable to oil painting, acrylic painting, gouache, also can be used for interior decoration, decoration, belong to the painting supply technical field.
Background technology
In existing technology, artist drawing normally adopts being coated with more than 3 layers the oven dry of coloured coating material on the primary backing and makes art canvas.The coloured coating material adopts polymer solution or its emulsion, as polyvinyl alcohol, ethene acetate homopolymers emulsion, the above latex composite compounding of the one pack system of acrylate copolymer emulsion or bi-component adds a greater number filler such as titanium dioxide, lithopone, talcum powder, calcium carbonate, zinc oxide etc. as the coating matrix and mixes.Then this coating material is applied to and makes art canvas on the primary backing.The defective of this art canvas is that the matrix that these high molecular polymers are made usually lacks enough flexibilities because of the coating after the film forming, embrittlement jackknifing and be full of cracks easily, and this has just influenced the serviceability of product.In order to address the above problem, need in the prescription of coating material, add the softness that plasticizer becomes coating., the plasticizer in the product coating loses the soft hardening of beginning but can escaping in the shelf put procedure.In addition, many countries progressively limit use to this poisonous chemicals of plasticizer.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of water polyurethane latex composite compounding color coat art canvas and production technology thereof are provided, adopt the high molecular polymer of different performance composite, add filler and make coating material; Repeat to be coated with more than three times and make art canvas, the serviceability of this art canvas is greatly improved.
Main solution of the present invention is achieved in that
Aqueous polyurethane emulsion of the present invention (APU) color coating art canvas, its compositing formula are in mass fraction:
Aqueous polyurethane emulsion (APU) 5-25 part
Interpolymer latex of polystyrene and acrylic ester (benzene emulsion) 15-40 part
Graining paste 0.05-8 part
Lithopone 30-60 part
Calcium carbonate 10-30 part
Hydroxypropyl cellulose 0.1-2 part
Ethanol 0.2-2 part
Glycerine 0.1-1 part
Sodium Benzoate 0.1-2 part
Pure water 10-30 part
Get half swelling, the heating of hydroxypropyl cellulose, stirring and dissolving with the total amount pure water; Become glue with aqueous polyurethane emulsion, interpolymer latex of polystyrene and acrylic ester, graining paste, glycerine, ethanol, Sodium Benzoate mixing and stirring; Get lithopone, calcium carbonate usefulness total amount pure water moistening then mixing of surplus, be stirred into coating paste under the normal temperature with above-mentioned glue; Be coated with three to five layers of coating pastes then on primary backing, dry oven dry is finished product.
The production technology of water polyurethane latex composite compounding color coat art canvas of the present invention, adopt following processing step: its compositing formula is in mass fraction:
1, the preparation of coating paste:
(1), get hydroxypropyl cellulose 0.1-2 part half swelling 6-12 hour with total amount pure water 10-30 part, fully be heated to 85-95 ℃ after the swelling, stir until dissolving fully; Become glue with aqueous polyurethane emulsion 5-25 part, interpolymer latex of polystyrene and acrylic ester 15-40 part, graining paste 0.05-8 part, glycerine 0.1-1 part, ethanol 0.2-2 part, Sodium Benzoate 0.1-2 part mixing and stirring;
(2), get lithopone 30-60 part, calcium carbonate 10-30 part and mix with above-mentioned glue with the moistening back of surplus of total amount pure water 10-30 part, be stirred into coating paste at normal temperatures, stand-by;
2, the production technology of coloured coating canvas:
(1), on primary backing, be coated with coating paste, coating machine progress speed 3-15 rice/minute;
(2) each is handled all over circulation heated-air drying after entering the drying room drying behind the coating paste; Bake out temperature is 65-200 ℃.
(3), coating 3-5 time, coating paste can adopt coating oven dry or the two kinds of modes of coating oven dry continuously of repeating.Each is all over coating layer thickness 0.01-0.5mm; The finished product total coating thickness is 0.3-1mm.
Primary backing of the present invention can be true qualities, bleaching, dyeing or scrape coating colour.Because product may contact human body, should consider the requirement such as environmental protection, safety and sanitation, health of product, so the content that should control the poisonous and harmful substance that may contain in the used raw and auxiliary material such as heavy metal, volatile toxic substance such as formaldehyde etc. is in allowed band.
Coating method of the present invention can adopt blade coating, spraying or roller coating.
The equipment of blade coating of the present invention can adopt single scraper gradation coated and dried or the continuous coated drying plant of multiple tracks scraper.
Material mixed at normal temperatures and makes the stable coating slurry, 800-1200 rev/min of mixer rotating speed, mixing time 0.5-1.5 hour during the use homogenizer will be filled a prescription when the present invention prepares burden.
Compared with the prior art the present invention has the following advantages:
The present invention is owing to selected aqueous polyurethane emulsion (APU) in prescription, this thermoplastic polyurethane emulsion has easy film forming, and is low temperature resistant, advantages such as good springiness, softness.But single with there being coating film forming top layer to be clamminess and defect of high cost, and aqueous polyurethane emulsion can not moistening well pigment, thus it painted to be not so good as other polymer waterborne emulsions easy like that.The art canvas that the present invention adopts aqueous polyurethane emulsion and latex of copolymer in cinnamic acrylic ester to be re-dubbed to add behind the coating matrix stuffing to make to be coated to behind the coating material oven dry of primary backing top layer to obtain has overcome these defectives.
The aqueous polyurethane that cost is higher is added in the latex of copolymer in cinnamic acrylic ester (trade name benzene emulsion) as polymeric plasticizer, overcome single with latex of copolymer in cinnamic acrylic ester (trade name benzene emulsion) as coating behind the matrix lack desirable flexibility and single use polyaminoester emulsion as matrix after the defective of sticky finiss.The two is composite has given the following superperformance of the polyurethane composite compounding coat art canvas-enough flexibilities and the elasticity of type epithelium sample as the coating matrix.Because the amount of the aqueous polyurethane emulsion that uses is few, so and exceed the cost that increases product.
