Abstract
The present invention relates to same with thermosetting compound material technical field, particularly relate to a kind of preparation method of same with thermosetting compound material.After preparation by the preparation of the preparation of resin adhesive liquid, strongthener, releasing agent; Mould applies the releasing agent of gained, on described releasing agent brushing first pass gained resin adhesive liquid after brush the resin adhesive liquid of second time gained again after form gel coating resin, and on described gel coating resin, lay the strongthener of gained and after adopting pressure roller to press down, form top layer at described strongthener surface pouring unsaturated polyester resin; The hot-forming rear demoulding is carried out at described skin surface cover glass paper.
Description
Technical field
The present invention relates to same with thermosetting compound material technical field, particularly relate to a kind of preparation method of same with thermosetting compound material.
Background technology
Along with the development of society, same with thermosetting compound material is at automotive field, household appliance technical field and electric field; Current same with thermosetting compound material is in shaping, solidification process, and owing to easily coming in contact with extraneous air, in shaping and solidification process, easily produce bubble, bubble too much easily causes composite surface quality poor.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of same with thermosetting compound material.
For achieving the above object, technical scheme of the present invention is: a kind of preparation method of same with thermosetting compound material: comprise the following steps:
1) preparation of resin adhesive liquid, described resin adhesive liquid is for adding after thermosetting epoxy resin, solidifying agent, defoamer, promotor, filler five kinds of materials mixing and stirring in a heated condition;
2) preparation of strongthener, described strongthener comprises the glasscloth after 90 ~ 180 DEG C of dry pre-treatment 3-5 minutes;
3) preparation of releasing agent, described releasing agent is mixing and stirring in a heated condition for adding water, after water glass, dust cork three kinds of materials;
4) compound material is prepared, the releasing agent of step (3) gained that mould applies, on described releasing agent brushing first pass step (1) gained resin adhesive liquid after brush the resin adhesive liquid of second time step (1) gained again after form gel coating resin, and on described gel coating resin, lay the strongthener of step (2) gained and after adopting pressure roller to press down, form top layer at described strongthener surface pouring unsaturated polyester resin;
5) the skin surface cover glass paper described in step (4);
6) hot-press solidifying;
7) demoulding;
In technique scheme, the part by weight between each component of described resin adhesive liquid is as follows: thermosetting epoxy resin: 100 parts; Solidifying agent: 3 ~ 10 parts; Promotor: 1 ~ 5 part; Defoamer: 1 ~ 3 part; Filler: 5 ~ 40 parts.
In technique scheme, described promotor comprises DMP-30 or EP-184 or trolamine.
In technique scheme, described defoamer comprises silicone oil or vegetables oil.
Described filler comprises pigment, aluminium hydroxide, aluminium powder.
In technique scheme, in described step (6), the composite material forming time is 1.8 ~ 4.5 hours, and mold temperature is 140 ~ 170 DEG C.
Heating temperature in described step (1) is 35 ~ 70 DEG C.
Heating temperature in described step (3) is 90 ~ 100 DEG C
The invention has the beneficial effects as follows: owing to having brushed twice resin adhesive liquid in the fabrication process, make composite material strength higher; Because strongthener adopts glasscloth, and carry out drying and processing before use, the effect of anticracking can have been strengthened on the one hand, can avoid on the other hand producing more bubble; Due at skin surface cover glass paper, the generation of bubble effectively can be reduced.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is present invention process schematic flow sheet;
