Abstract
The invention discloses an offset printing spray powder and a preparation method thereof. The offset printing spray powder includes the following components, by weight, 70-90% of corn starch, 5-15% of calcium carbonate and 5-15% of aluminum sulfate, and also includes a hydrophobic surfactant or a hydrophilic surfactant. The offset printing spray powder is prepared from the corn starch as a basic material so that the spray powder is free of carcinogenicity, is stable in chemical properties and is not reacted with components in a fountain solution. The pulverized spray powder is coated by the hydrophobic surfactant or the hydrophilic surfactant, so that the powder is ensured to have round degree and hydrophobicity/hydrophilicity and is convenient to subject to modification of hydrophobicity or hydrophilicity, thereby improving the adaptability and variety of the products; furthermore, according to subsequent processing demands, such as oily film coating or aqueous gloss oil coating, related hydrophobic or hydrophilic spray powders can be produced.
Description
Technical field
The present invention relates to a kind of printing to dust and preparation method thereof, particularly relate to a kind of offset printing and dust and preparation method thereof.
Background technology
Dusting is requisite operation in current Modern High-Speed multi-color blanket technique.Printing dust in press in order to prevent printed matter in printing process set-off, accelerate dry and reduce collection time upper and lower two pieces of paper between frictional force, make collection neat.The exit slot of offset printing is typically equipped with the sprinkling mouth dusted, allowing dusts evenly is sprinkling upon on printing paper, form certain obstruct, in order to separate the printed sheet of non-complete drying, accelerate ink dry coal speed, to prevent that printed matter curing ink from failing in time dry, set-off is caused at the back side adhere to a piece of paper in paper sheet stacking process, affects print quality.But tradition is dusted and had following defect: 1. tradition is dusted with talcum powder is base-material, owing to can cause airborne dust in powder sprinkling process, long-term suction can be carcinogenic; 2. talcous main component is the hydrated magnesium silicate of alkalescence, but all contains acidic substance (being mainly organic acid or mineral acid) in the fountain solution of printing, chemical reaction may occur and cause the change of powder property, affecting its result of use; 3. the modification of the hydrophilic or hydrophobic aspect that is not easy to do.Therefore, be necessary to dust and preparation method thereof to existing offset printing to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of offset printing and dusts and preparation method thereof, health environment-friendly, stable chemical performance be easy to carry out wetting ability or hydrophobicity process to surface of dusting according to demand.
The present invention solves the problems of the technologies described above the technical scheme adopted to be to provide a kind of offset printing and to dust, and comprises following component: W-Gum, calcium carbonate and Tai-Ace S 150.
Above-mentioned offset printing is dusted, and wherein, described offset printing also comprises hydrophobic active agent or hydrophilic active agent in dusting.
Above-mentioned offset printing is dusted, and wherein, the weight percentage of described offset printing each component in dusting is as follows: W-Gum 70 ~ 90%; Calcium carbonate 5 ~ 15%; Tai-Ace S 150 5 ~ 15%.
The present invention, for solving the problems of the technologies described above the preparation method also providing a kind of above-mentioned offset printing to dust, comprises the steps: a) to be base-material with W-Gum, mixed calcium carbonate and Tai-Ace S 150, stirs to make mixing and dust; B) described mixing to be dusted pulverizing; C) hydrophobic active agent or hydrophilic active agent are coated on the mixing after pulverizing to dust surface, carry out surface modification treatment; D) mixing after surface modification treatment dusted oven dry, obtained offset printing is dusted.
The preparation method that above-mentioned offset printing is dusted, wherein, mixes each compositions in weight percentage configuration in dusting as follows: W-Gum 70 ~ 90%, calcium carbonate 5 ~ 15%, Tai-Ace S 150 5 ~ 15% in described step a).
The preparation method that above-mentioned offset printing is dusted, wherein, the particle fineness that the mixing after pulverizing in described step a) is dusted is 200 order ~ 500 orders.
The preparation method that above-mentioned offset printing is dusted, wherein, in described step c), hydrophobic active agent is dimethyl silicone oil.
The preparation method that above-mentioned offset printing is dusted, wherein, in described step c), hydrophilic active agent is water-based silicone oil.
The present invention contrasts prior art following beneficial effect: offset printing provided by the invention is dusted and preparation method thereof, take W-Gum as base-material, non-carcinogenesis; Stable chemical performance, can not react with the composition in fountain solution; Hydrophobic active agent or hydrophilic base table promoting agent are coated on the surface of dusting after pulverizing, guarantee the roundness degree of powder particle and dredge/wetting ability, be conducive to the modification processing carrying out hydrophilic or hydrophobic aspect, increase adaptability and the diversity of product, and can according to following process demand, as covered oiliness film or water-based gloss oil etc., hydrophilic or the hydrophobic type of producing corresponding type dust, thus reach good result.
Embodiment
To dust and preparation method thereof with regard to offset printing below and be specifically described, the invention is not restricted to following examples, described method is ordinary method if no special instructions, and described material is commercial goods.Offset printing provided by the invention is dusted, and wherein, comprises following component: W-Gum, calcium carbonate and Tai-Ace S 150.The weight percentage of each component is as follows:
W-Gum 70 ~ 90%;
Calcium carbonate 5 ~ 15%;
Tai-Ace S 150 5 ~ 15%.
The preparation method that offset printing provided by the invention is dusted, comprises the steps:
Step a) take W-Gum as base-material, mixed calcium carbonate and Tai-Ace S 150, stirs to make mixing and dust; Described mixing in dusting the configuration of each compositions in weight percentage as follows: W-Gum 70 ~ 90%, calcium carbonate 5 ~ 15%, Tai-Ace S 150 5 ~ 15%.
Described mixing is dusted pulverizing by step b); The particle fineness that mixing after pulverizing is dusted is 200 order ~ 500 orders; Concrete particle fineness and comprehensive proportion different according to the product type of different offset printing paper, such as according to thickness screening area point model: 500 dust corresponding 500 orders, 300 dust corresponding 300 orders, and 200 dust corresponding 200 orders etc.
