The preparation technology adopts mechanized production, thus being easy in industrial mass production; by scientifically controlling technological parameters such as glue ratio, glue solution viscosity, glue amount, temperature of a drying cylinder, time from rolling up to cutting, and the like, the obtained wallpaper composite material product does not have bubbles, mesh points or white points, and has the good characteristics of being environmentally friendly, strong in third dimension, rich in colors, good in shape stability, etc.
Description
technical field
The invention belongs to architecture decorative product technical field, relate to a kind of combined producing tech, relate in particular to a kind of composite fibre paper and the chemical fibre combined producing tech without spinning filament.
Background technology
At present, wallpaper on market be all generally taking plant fiber material produce body paper as base material, taking igelite or other fibrous material etc. as surface layer, through calendering or coating and printing, embossing or foaming and make, but the class of such wallpaper is compared with low and expansion and contraction is large, uses after a period of time and easily cause and reveal seam and inaccurate to spending.And adopt the wall cloth of nonwoven as base cloth, and its pattern stereoscopic impression deficiency, visual sensory is not good, and decorative effect is high-grade not, can not meet the needs of high-grade wall fitting.
Along with the progress of paper technology, on hanging raw stock market, occur a kind of taking chemical fibre and string as raw material, the low expansion and contraction nonwoven hanging raw stock forming through manufacturing paper with pulp, the chemical fibre that itself and expansion and contraction are low is compound without spinning filament, and the composite wallpaper forming has started to use at high-end decoration market.But it is poor, easy to foaming that bonding intensity appears in this composite wallpaper in recombination process, occurs blotting inequality in printing process, produce mesh and white point phenomenon.Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of combined producing tech, to overcome described defect of the prior art.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of production technology of composite fibre paper multifilament, and the prepared wallpaper composite of this production technology has that bonding intensity is good, non-foaming, not modification, the feature such as third dimension is strong, color is abundant.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of production technology of composite fibre paper multifilament, described composite fibre paper refers to chemical fibre and the string body paper forming of manufacturing paper with pulp, itself and chemical fibre carry out the production technology of multifilament without spinning filament, comprise volume operation, join glue process, upper glue process, compound baking operation, winding process and cut packing process:
1), upper volume
Utilize glue point to shift compounding machine, chemical fibre is located to fabric without spinning filament and unreels end, and reverse side is used for compound; Composite fibre nonwoven hanging raw stock is located at base material and unreels end, and to be used for gluing compound in its front;
2), join glue
In extraordinary polyurethane resin compound adhesive, add butanone, DMF, promoter and bridging agent, its weight ratio is 50 ~ 70:20 ~ 30:2 ~ 5:2 ~ 5:6 ~ 10;
3), gluing
Upper glue roller adopts 20-35 order rhombus or circular glue point roller, and base material is put between roller and pressure roller by glue, and the coating weight of glue is 15-30 g/m
2;
4), compound oven dry
Drying tube temperature is set to 90-120 DEG C;
5), rolling and cut packing
The grammes per square metre of nonwoven hanging raw stock is 100-150 g/ m
2, chemical fibre is 15-50g/ m without the grammes per square metre of spinning filament
2; Rolling door width is set to 400-1700mm, and take-up diameter is 800mm.
On the basis of technique scheme, the speed of service that glue point described in step 1) shifts compounding machine is 15-40 m/min, and the pressure of compounding machine pressure roller is 2.5-6kg/cm
2.
Step 2) described in join in glue process, in extraordinary polyurethane compound adhesive, successively add successively butanone, DMF and promoter, the rotating speed that agitator starts is 200-300 rev/min, after stirring, rotating speed is brought up to 800-1000 rev/min, after becoming milky, glue add again bridging agent to continue to stir, and evenly rear stand-by.
The present invention is the quality that ensures wallpaper composite, and the node step of multifilament technique is controlled, specific as follows:
1. select suitable sizing material and proportioning: the present invention adopts chemical fibre compound without spinning filament and composite fibre nonwoven hanging raw stock, be difficult to bonding fiber and all contain in them, join adhesive process so of the present invention, in extraordinary polyurethane compound adhesive, add a certain amount of DMF, promoter and bridging agent.Wherein on the polyurethane macromolecular main chain in extraordinary polyurethane composite gel, contain many carbamate groups, ester group, amide groups, the large intermolecular hydrogen bond that is easy to generate, has strengthened the cohesive force of compound adhesive, strengthens the adhesion strength of compound adhesive.DMF has fine dissolution to the high polymer of low solubility, can strengthen the binding strength of nonwoven hanging raw stock and chemical-fibres filaments, and the intensity of reinforced composite is eliminated the foaming because of bonding not firm generation; And GC5-A is a kind of special polyester adhesion promoter, can accelerate and sizing material reaction speed, shorten follow-up hardening time, and can improve adhesive force, heat endurance and resistance to water and the chemical resistance of ink, eliminate site and white point; Bridging agent reacts with water-base resin in the time of heat treatment, can significantly improve the performance of resin.
2. control gelatin viscosity: mainly control by butanone solvent consumption.During with glue point roller coat glue, transfer to glue on base material always with the same distribution of shapes in same site, as large in the viscosity of glue, levelability is just poor, glue point one by one can not form the glued membrane of uniformity, causes joint product to look like and is bonded together with many thickly dotted micelles, and outward appearance is plain, transparency is also poor, and produces white point; As gelatin viscosity is little, spread is few, easy to foaming.
3. control spread: spread is little, bonding intensity is poor, easy to foaming; Spread is large, not only causes waste, also easily causes the uneven white point hole producing of blotting to print.
4. control drying tube temperature: for making sizing material reach good bonding effect, after compound, remove in sizing material solvent as far as possible and can not destroy other auxiliary agent character, in this glue proportioning, 79.6 DEG C of primary solvent butanone boiling points, 120 DEG C of minimum boiling points in auxiliary agent, so drying tube temperature is controlled between 90-120 DEG C.
5. rolling is to the time of cutting: because sizing material has a curing time, after rolling, reel need be wrapped with plastic paper, solidifies after substantially completing (approximately 12 hours) and cuts packing again until sizing material, in order to avoid cause fabric and the decline of base material bonding intensity, causes arch camber.
Adopt technique scheme, beneficial effect of the present invention is:
The present invention adopts mechanization production, is easy to large-scale industrialization and produces, and has reduced production cost.The present invention is by carrying out science control to technological parameters such as sizing material proportioning, gelatin viscosity, spread, drying tube temperatures, the wallpaper composite products of producing is non-foaming, without site and white point phenomenon, the good characteristics such as there is environmental protection, third dimension is strong, color and luster is abundant, type stability is good.
