Abstract
The invention discloses a single-component normal-temperature curing coating solution for endowing a polyolefin film with a long-lasting anti-fogdrop function, and belongs to the field of chemical industries. The coating solution consists of the following raw materials in portions by weight: 2-10 portions of aqueous acrylate resin, 10-40 portions of inorganic sol, and 50-80 portions of alcohol-water mixed liquid. The coating solution has the characteristics of simplicity for preparation, fast curing capability under the normal temperature condition, capability of realizing on-line coating, strong binding force with the film when coated on the surface of the film, long lasting period for non-drop fog elimination and good functions.
Description
Technical field
The present invention relates to a kind of single component ambient cure masking liquid that makes polyolefin film have long-acting anti-droplet function, belong to chemical field.
Background technology
Because of the polyolefin film interfacial surface tension is lower, and be hydrophobic, will form intensive little droplet, influence printing opacity and the underproduction if use agricultural booth.At present, the drip of awning film fog dispersal technology has become the important technology that modern agriculture is produced.
The drip fog dispersal technology of agriculture greenhouse film mainly contains two types: interior interpolation surfactant method and outer cladding process.Its drip phase of plastic sheeting for farm use and fog dispersal phase that interior additive process is produced are shorter, and generally at three to four months, separating out of drip agent etc. pollutes crop in the canopy and soil easily besides.Cladding process be will preparation the drip fog dispersal liquid surface that is coated on the canopy film make it have drip fog dispersal function.It is the masking liquid of main component and the plastic sheeting for farm use of coating thereof by aluminium hydroxide and anion surfactant that patent " antifogging agent composition and the plastic sheeting for farm use that applies with it " (China Patent No. ZL 96107385.3) discloses a kind of, have the drip characteristics preferably that disperse fog, but its viscosity is bigger, need strict its viscosity of control and order of addition(of ingredients) during production, otherwise easily precipitate, coated plastics film also needs surface treatments such as corona discharge.Patent " spraying type agricultural plastic greenhouse film fog dispersal water-dropping proof agent and preparation method thereof " (China Patent No. ZL 02153861) discloses a kind ofly to be made up of A (aqueous solution of colloid silica and water-soluble high-molecular substance), two kinds of components of B (aqueous solution of quaternary cationics, film coalescence aid and silane coupling agent).After the coating, the drip fog dispersal phase can reach 6 months.But it can not realize online coating, after needing to detain canopy, behind user's thin up, sprays in canopy voluntarily, dries through the long period, just has drip fog dispersal function, comparatively trouble.
Up to now, yet there are no does not need the plastics film surface is handled, and realizes that then online coating produces the patent disclosure of used masking liquid.
Summary of the invention
In order to overcome the problem of above-mentioned existence, the object of the present invention is to provide a kind of single component ambient cure masking liquid that makes polyolefin film have long-acting anti-droplet function, it is simple that it has preparation, get final product fast setting under the normal temperature condition, can realize online coating, be coated on film surface and the film bonding force is strong, the drip fog dispersal characteristics that the lasting period is long, function is good.
Technical scheme of the present invention is: a kind of single component ambient cure masking liquid that makes polyolefin film have long-acting anti-droplet function, it is characterized in that, raw material by following weight parts is formed, water-and acrylate resin 2～10, inorganic sol 10～40 and alcohol-water mixture 50～80.
Described inorganic sol is silicon sol or aluminium colloidal sol, and particle diameter is 15～60nm, and the pH value is 5～8.
The interpolation weight ratio of alcohol and water is 2～5: 1 in the described alcohol-water mixture, and the mass percentage concentration of described alcohol is greater than 90%, and described alcohol is monohydroxy-alcohol, dibasic alcohol or the alcohol mixture of the two.
Water in the described alcohol-water mixture is distilled water or deionized water.
Compound method: take by weighing raw material for standby by above-mentioned weight part, under the room temperature condition, earlier with water-and acrylate resin stirring and dissolving in alcohol-water mixture as dispersion medium in, add inorganic sol again, stir, can obtain required liquid.
The invention has the beneficial effects as follows:
(1). this masking liquid surface tension is starkly lower than the polyolefin film surface tension, is 15～20Nm
-1, not needing that film surface is carried out corona treatment can apply;
(2). this masking liquid has the double effects of drip performance and fog dispersal performance after film surface forms coating, it is synchronous with the film lifetime that validity period can reach;
(3). after masking liquid applies, can very fast curing under the film surface normal temperature condition, can film bubble surface be applied in the cooling and shaping stage of film, thereby realize online coating;
(4). adopt conventional industrial chemicals after simple blend, can use, easy to use.
