Environment-friendly type adhesive for coating printing and dyeing as well as preparation method and application thereof

The invention discloses an environment-friendly type adhesive for coating printing and dyeing as well as a preparation method and application thereof. The adhesive is prepared from the following components through reacting: a soft monomer, a hard monomer, a cross-linking monomer, a comonomer, an emulsifier, an initiator and a formaldehyde catching agent. A preparation process comprises the following steps: adding xanthan gum and 1/3 of soft water in sequence and stirring for dissolving; then adding selenious acid; dropwise adding 4-(2-ethylamino)benzene-1,2-diphenol; carrying out thermal insulation reaction; regulating the pH (Potential of Hydrogen) to be neutral; then adding 2/3 of soft water and 1/2 of the emulsifier and dissolving; then dropwise adding mixed liquid of the soft monomer,the hard monomer, the cross-linking monomer, 1/2 of the initiator and 1/2 of the emulsifier; carrying out thermal insulation reaction and rapidly raising the temperature; rapidly adding the comonomerand 1/2 of the initiator and stirring; then adding the formaldehyde catching agent; rapidly cooling and regulating the pH; cooling and carrying out thermal insulation reaction; naturally cooling, andfiltering and discharging to obtain the environment-friendly type adhesive. When the adhesive disclosed by the invention is used for carrying out coating printing, no formaldehyde is released and environmental protection is realized.

Weather-resistant printing ink, manufacturing method and testing method of weather-resistant printing ink

The invention discloses weather-resistant printing ink, a manufacturing method and a testing method thereof, and the weather-resistant printing ink is mainly prepared from the following raw materials in parts by weight: 40-60 parts of polyacrylate oligomer, 8-15 parts of reactive diluent, 4-10 parts of photoinitiator, 10-15 parts of pigment, 3-6 parts of filler, 1-3 parts of dispersing agent and 1-2 parts of assistant. And the degree of functionality of the polyester acrylate oligomer is between 3 and 7. The higher the functionality of the polyester acrylic acid is, the stronger the reaction activity is, so that the curing speed can be improved, but the too high functionality can cause the increase of the viscosity and the reduction of the flexibility. The printing ink has the advantages of favorable toughness, appropriate drying speed, favorable filler wetting effect, favorable oleophylic-hydrophilic balance and favorable chroma resistance. Through the matching of the components and the manufacturing method, the weather-resistant printing ink has better weather resistance, the color difference change is smaller in different areas and different temperatures, and the distinguishing degree of printed matters is effectively improved.

Anti-clogging and high-temperature-resisting polyvinyl butyral spray ink

The invention relates to the field of printing ink and particularly relates to anti-clogging and high-temperature-resisting polyvinyl butyral spray ink. The ink is prepared from the following raw materials in parts by weight: 0.2-0.5 part of glyzinc, 2-5 parts of lauryl alcohol polyoxyethylene, 0.1-0.2 part of lithium acetate, 6-8 parts of a magnesium ferrite pigment, 24-32 parts of dimethyl carbonate, 3-5 parts of phenyl salicylate, 2-3 parts of stearyl alcohol, 8-12 parts of absolute ethyl alcohol, 26-35 parts of polyvinyl butyral resin and 1-2 parts of auxiliaries. The ink takes the polyvinyl butyral resin as an adhering material, is good in softness and flexibility and good in transparency, can resist light and cold, and can be adhered to the surfaces of various kinds of materials well. The lithium acetate and the glyzinc can prevent the ink from crystallizing and improve the heat resistance of coatings, and the auxiliaries can improve the wettability of ink so as to enable the ink to be easily sprayed. The ink has the advantages of low toxicity, environmental friendliness, controllable viscosity and good liquidity, is prevented from color change and falling off in high-temperature environment, is moderate in drying speed, is not easily clogged, and is efficient in spraying.

A kind of water-based ultra-high-speed spraying joint glue and preparation method thereof

The invention discloses a water-based ultra-high-speed spraying filter tipping adhesive and a preparation method thereof. The method uses polyvinyl alcohol as a protective colloid, and isomeric alcohol polyoxyethylene ether as an emulsifier to produce a ternary copolymer emulsion of vinyl acetate, methyl methacrylate, and acrylic acid, further improves fluidity and cohesiveness by adding a plasticizer and a polyvinyl alcohol aqueous solution, effectively lowers residual vinyl acetate monomers by vacuuming while stirring under relatively high temperature, and uses ionized water to adjust viscosity, thereby producing the ultra-high-speed spraying filter tipping adhesive suitable for a spraying gluing cigarette making machine. The method does not use any alkylphenol ethoxylates emulsifier which has accumulative harm to human body; and on the premises of low viscosity and low solid content, the produced filter tipping adhesive has high paper adhesion and high drying speed, and can achievestable adhesive supply on the spraying gluing cigarette making machine which is working at a speed of 20000 cigarettes per minute. The produced cigarette does not show air leak, filter tipping disconnection, wrinkles, or other undesirable phenomena, and has low a rejection rate.
