Description
The technical field is as follows:
the invention relates to the technical field of silk screen printing and dyeing, in particular to a printing technology applied to the blanket industry, and especially relates to aqueous environment-friendly double-curing blanket glue and a preparation method thereof.
Background art:
the carpet industry has developed very rapidly in recent years. China has become the production base of world blankets at present, the yield is at the top of the world, and a plurality of blankets are used for export. At present, the blanket printing and dyeing industry mostly adopts common water-resistant vinyl acetate photosensitive glue. The blanket is thick, the silk screen used in printing is about 60 meshes, the pressure of the magnetic bar is 15Kg/m2, so that the photosensitive emulsion is not wear-resistant, and the photosensitive emulsion is degummed generally after about 50-100 times of printing, thereby seriously affecting the printing efficiency. Therefore, the front and back surfaces of the photosensitive adhesive are coated with the soft slow-drying polyurethane paint to protect the photosensitive film in the printing process, the plate making process can be completed only by coating the photosensitive adhesive twice through a paint absorber, the plate making time is long, and meanwhile, the slow-drying soft polyurethane paint (with the boiling point of 150 ℃) contains an organic solvent, and the volatilization of the organic solvent also causes adverse effects on the surrounding environment.
The invention content is as follows:
the invention aims to provide synthesis and preparation of aqueous environment-friendly dual-curing blanket glue aiming at the defects of the traditional process technology, effectively solves the problems of longer time consumption, poor plate-making fastness and non-wear resistance of blanket printing, and simultaneously solves the problem of volatilization of an organic solvent of soft slow-drying polyurethane paint (with a boiling point of 150 ℃) so as to meet the requirements of safety and environmental protection. The blanket glue adopts epoxy acrylic acid synthetic colloid, UV monomer and diazo resin, the whole process does not need to use slow-drying soft polyurethane paint and the like during plate making, and the blanket glue can be quickly cured, and is soft and wear-resistant in plate making.
The invention provides a preparation method of aqueous environment-friendly double-curing blanket glue, which comprises the following steps:
1) carrying out synthetic reaction on a proper amount of polyvinyl alcohol, water, vinyl acetate and acrylic ester to obtain a colloid;
2) adding proper amount of epoxy propylene resin, UV monomer and UV photosensitizer into the obtained colloid in turn, and emulsifying at high speed to form colloid
3) Mixing appropriate amount of diazo resin with the colloid uniformly; and (5) obtaining the product.
Further, in the step 1), 50-100 parts by weight of polyvinyl alcohol, 280-570 parts by weight of water, 300-500 parts by weight of vinyl acetate and 80-120 parts by weight of acrylate.
Preferably, the glass transition temperature of the colloid obtained in step 1) is 8-12 ℃.
Further, in the step 2), the epoxy propylene resin accounts for 80-120 parts by weight, the UV monomer accounts for 80-120 parts by weight, and the UV photosensitizer accounts for 1 part by weight.
Further, the UV monomer is selected from one of tripropylene glycol diacrylate (TPGDA), dipentaerythritol hexaacrylate (DPHA), hexanediol diacrylate (HDDA), diethylene glycol diacrylate Phthalate (PDDA), neopentyl glycol diacrylate (NPGDA), pentaerythritol triacrylate (PETA), trimethylolpropane triacrylate (TMPTA), ethoxylated trimethylolpropane triacrylate (EO-TMPTA), isobornyl methacrylate (IBOMA), or dipropylene glycol diacrylate (DPGDA).
Further, the diazo resin added in the step 3) was 5/1000 parts by weight.
The invention also provides the aqueous environment-friendly double-curing blanket glue prepared by the preparation method.
The invention further provides application of the carpet glue in carpet printing
The invention has the beneficial effects that:
1) the blanket glue is thicker when being glued, and the acrylate is added in the blanket glue synthesis of the invention, thereby well improving the hardness of the blanket glue plate making, leading the hardness of the blanket glue plate making to be better, leading the plate making to be capable of being used in the environment below 5 ℃, and leading the plate not to crack and be not crisp;
2) the carpet glue of the invention has diazo resin and UV photosensitizer at the same time, and has dual curing reaction in the photosensitive process, so the carpet glue has high curing speed and good wear resistance, and can be printed for 5 ten thousand times;
3) when the blanket glue in the prior art is used, the front and back surfaces of the photosensitive glue are coated with the soft slow-drying polyurethane paint to protect the photosensitive film in the plate making process, the plate making process is completed by a paint absorber twice, the consumed time is long after 24 hours each time, and the environmental protection is greatly influenced due to the volatile smell of the organic solvent of the soft slow-drying polyurethane paint (the boiling point is 150 ℃). The carpet glue provided by the invention can be directly used in the using process without adding a protective agent.
