Abstract
The invention relates to a dripping material formula. Apart from the conventional major material, namely, polyurethane resin or bisphenol type A epoxy resin, D,1-lactide is added as a major plasticizer, and butylated hydroxyanisole is added as an antioxidant. By selecting a plasticizer material and adjusting the proportional relation of each raw material, the occurrence rate of in-vivo macroscopic bubbles or needle eyes and edge shrinkage is reduced by about 70 percent. Moreover, the antioxidant of butylated hydroxyanisole (BHA) of an accurately-calculated ratio is added, so that the yellowing time is delayed by about 3 times than before.
Description
Technical field
The present invention relates to a kind of plastic drop material formula, belong to printing material field.
Background technology
Along with the progress of printing technology and the demand of printing market are in continuous improve, the Plane performance such as overlay film, glazing form can not meet market, moulds having three-dimensional stereo effect, bright in lusterly full drip that a molding product is answered the market requirement and constantly improve of explained hereafter and drip.
Dripping molding technology is mainly to utilize thermoplastic macromolecule material to have glutinous fluidity under certain condition, recover again at normal temperatures solid-state characteristic, use appropriate means and special instrument, in the time that it is viscous state, fashioned on request different shapes, and then the technology of curing molding under normal temperature.Drip the mode of moulding and be mainly divided into 1. heating instillation types; 2. pressurization instillation type; 3. hot pressing extrusion type.Heating instillation type is that thermoplastic copolymer liquid material is heated before instillation, and temperature remains on 60-70 degree Celsius, makes plastic material become viscous state, thereby instils at printing product surface.
At present heating instillation type finished product often can run into following problem: drip molded after, in body, have bubble, there are macroscopic bubble or pinprick in inside; There is in addition shrinkage cavity phenomenon at edge, affect the yield of finished product; In use color gradient yellow.
Summary of the invention
One of technical problem to be solved by this invention be drip molded after, in body, have macroscopic bubble or pinprick and edge shrinkage cavity phenomenon; Two of technical problem to be solved is color gradient yellow.
Drip and mould formula as the one of first aspect present invention, except traditional major ingredient polyurethane resin or bisphenol A type epoxy resin, add D, 1-rac-Lactide is as main plasticizer, and add using butylated hydroxyanisol as antioxidant, select by plasticizer materials, and adjust the proportionlity of each raw material, in body, there are macroscopic bubble or pinprick and edge shrinkage cavity phenomenon incidence to reduce by 70% left and right, and add the antioxidant butylated hydroxyanisol (BHA) of meticulous calculating ratio, making the yellow time of origin interest for delinquency of color gradient is 3 times of original left and right.
Embodiment
In order further to understand the present invention, below in conjunction with the present embodiment, preferred version of the present invention is described in detail, but should be appreciated that these description are just for further expressing technical characterictic of the present invention, realizing approach, is not the restriction to claim of the present invention.
