Abstract
The present invention relates to the technical field of high molecular polymer emulsion type glue, especially provides a water-soluble hot-melt glue. In the preparation method of the water-soluble hot-melt glue, the water-soluble hot-melt glue contains a binder, a viscosity increaser, a filler, an organic silicon defoamer, an organic silicon mildew preventive, other assistants and water. The preparation method of the water-soluble hot-melt glue is characterized in that the dosage proportion of the components, based on a total of 100 parts by weight of non-volatile components, is as follows: 10 to 40 parts of the binder, 10 to 30 parts of the viscosity increaser, 20 to 60 parts of the filler, 10 ppm to 100000 ppm of the organic silicon defoamer, 1 ppm to 10000 ppm of the organic silicon mildew preventive, 0.1 to 5 parts of assistants and 100 to 300 parts of water. Compared with the prior art, the water-soluble hot-melt glue fills the domestic gap in the field and is worth promotion and application.
Description
[technical field]
The present invention relates to technology high molecular polymerization emulsion-type glue field, specifically provide water-soluble hot-melt adhesive glue.
[background technology]
Along with China's medicine equipment and foodstuffs industry fast development, very needing a kind of is the emulsion-type heat-sealing chewing-gum water that base-material is further processed with the ethylene-vinyl acetate copolymer resins.Disposable medical treatment product were to pass through strict sterilising packaging before syringe, transfusion device, hospital gauze, sterilization cotton etc. are in arriving medical personnel's hand.This wrapping material, one side is transparent plastics film or composite membrane, another side is to be printed on name of product, the paper of comments such as specification brand, this paper is easily with pulling brokenly.
Plastics film is PVC or PE composite membrane normally, make paper and PE composite membrane bonding, and this paper will pass through special processing treatment in advance, normally is coated with one deck hot-melt adhesive glue.This glue is domestic, and what oneself can produce preparation is to be solvent with toluene, heating for dissolving EVA hot-melt resin, add petroleum resin, Microcrystalline Wax, terpine resin again, rosin etc. are composite to form, because of there being a large amount of toluene to exist, so be non-environmental type glue, do not welcome by the direct labor, do not accepted by external businessman yet.
[summary of the invention]
Purpose of the present invention overcomes the defective of prior art, and a kind of prescription of novel aqueous hot-melt adhesive glue is provided, and viscosity height, thermally melting are strong, fill a hole in the market, and satisfy enterprise demand.
For achieving the above object, design a kind of preparation method of water-soluble hot-melt adhesive glue, comprise binding agent, tackifier, filler, silicone antifoam agent, organosilicon mould inhibitor and other auxiliary agent and water, it is characterized in that filling a prescription by non-volatile component total amount is 100 parts of weight usage ratio is as follows:

High ethene EVA emulsion 90-50 part
Low ethene EVA emulsion 10-50 part;
Tackifier are selected a kind of or several compositions in the following latex for use: terpene phenolic resin emulsion, modified rosin emulsion, rosin milk, acrylate copolymer emulsion, ethylene-vinyl chloride copolymer emulsion, vinyl acetate between to for plastic-chloroethylene copolymer emulsion, binding agent and tackifier usage ratio, by weight:
Binding agent 10-40 part
Tackifier 10-30 part;
Filler is selected silicon powder, lime carbonate, silica powder, talcum powder, mica powder, kaolin for use, wilkinite is a kind of or several mix;
Select for use nontoxic organosilicon quaternary ammonium salt as mould inhibitor.
The present invention compare with prior art have that technology is simple, cost is low, advantage, and this research high molecular polymerization developing direction both at home and abroad that links closely, market-oriented, fill up China's blank, satisfy market in urgent need, can meet the invested in plant manufacturing technique requirent, can produce environment-friendly type, the no three wastes, water-based, do not contain organic solvent, nontoxic, the new type hot-melt adhesive glue that do not have blast, no danger of combustion, be worthy of popularization.
