Abstract
The invention provides an adhesive preparation method, comprising the following steps: preparing materials according to the following weight ratios: 40-50% of waste polystyrene foamed plastic, 27-40% of organic solvent, 17-30% of plasticizer and 1-3% of additive; adding the additive into the organic solvent, stirring uniformly, pressing the waste polystyrene foamed plastic into the organic solvent until being completely dissolved, adding the plasticizer, and stirring uniformly to prepare the adhesive, wherein the organic solvent is ethyl acetate, the plasticizer is dioctyl phthalate, and the additive is creeping oxalis extracting solution. The adhesive preparation method provided by the invention can be used for effectively improving the utilization rate of waste polystyrene foamed plastic.
Description
Technical field
The present invention relates to non-setting adhesive technical field, particularly a kind of preparation method of the binding agent for non-setting adhesive.
Background technology
For used fast food lunch-box, pack the porous plastics of instruments/equipment and produce the process of the scrap stock the like waste after foam article, from environmental angle, be important work always.Chinese patent CN1019912C provides a kind of non-setting adhesive and method for making thereof, it can utilize waste polystyrene foam plastic to prepare a kind of binding agent that can be used for non-setting adhesive as main raw material, but it is also present in room for promotion to the utilization ratio of waste polystyrene foam plastic.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of binding agent preparation method, to reduce or to avoid problem noted earlier.
For solving the problems of the technologies described above, the present invention proposes a kind of binding agent preparation method, it comprises the steps: to get out material by following weight ratio: waste polystyrene foamed plastics 40-50%, organic solvent 27-40%, softening agent 17-30%, auxiliary material 1-3%; In described organic solvent, add described auxiliary material, stir, then described waste polystyrene foamed plastics is pressed into described organic solvent, till dissolving completely, then add described softening agent, stir, described binding agent can be obtained; Described organic solvent is ethyl acetate, and described softening agent is dioctyl phthalate (DOP), and described auxiliary material is Herba Oxalidis Corniculatae extraction liquid.
A kind of binding agent preparation method provided by the present invention, it effectively can promote the utilization ratio of waste polystyrene foam plastic.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now the specific embodiment of the present invention is described.
The concrete preparation method of binding agent provided by the present invention is:
First polystyrene foamed plastics waste is carried out cleaning, drying, get out material by following weight ratio: waste polystyrene foamed plastics 40-50%, organic solvent 27-40%, softening agent 17-30%, auxiliary material 1-3%.In described organic solvent, add described auxiliary material, stir, then described waste polystyrene foamed plastics is pressed into described organic solvent, till dissolving completely, then add described softening agent, stir, described binding agent can be obtained.
Herba Oxalidis Corniculatae extraction liquid can strengthen the solubleness of waste polystyrene foamed plastics in ethyl acetate.
A kind of binding agent preparation method provided by the present invention, it effectively can promote the utilization ratio of waste polystyrene foam plastic.
Although it will be appreciated by those skilled in the art that the present invention is described according to the mode of multiple embodiment, not each embodiment only comprises an independently technical scheme.So describe in specification sheets be only used to clear for the purpose of; specification sheets should integrally be understood by those skilled in the art, and regards technical scheme involved in each embodiment as the mode that mutually can be combined into different embodiment to understand protection scope of the present invention.
The foregoing is only the schematic embodiment of the present invention, and be not used to limit scope of the present invention.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present invention and principle, amendment and combination, all should belong to the scope of protection of the invention.
