Abstract
The present invention relates to same with thermosetting compound material technical field, particularly relate to the preparation method of heat-reactive phenolic resin matrix material.By the preparation of molding compound, the preparation of strongthener, mixes molding compound with strongthener; After mixture being poured into heating in metal pair mould, pressurization; Carry out cooling curing and the demoulding again.
Description
Technical field
The present invention relates to same with thermosetting compound material technical field, particularly relate to the preparation method of heat-reactive phenolic resin matrix 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; Because current same with thermosetting compound material easily produces bubble in preparation process; And the easy shattered crack in demoulding rear surface; When solidifying, solidification effect is poor, and hardness is not high.
Summary of the invention
The object of the present invention is to provide the preparation method of heat-reactive phenolic resin matrix material.
For achieving the above object, technical scheme of the present invention is: the preparation method of heat-reactive phenolic resin matrix material: comprise the following steps:
1) preparation of molding compound, described molding compound by after resol, amido functional group silane, ethanol and glass fibre four kinds of material Homogeneous phase mixing, then carries out tearing pine and oven dry;
2) preparation of strongthener, described strongthener is the staple fibre after 90 ~ 180 DEG C of dry pre-treatment 3-5 minutes;
3) strongthener in the molding compound in step (1) and step (2) is mixed to form mixture;
4) compression molding: the mixture in step (3) is poured in the mould scribbling releasing agent carry out heating, pressurize aftershaping;
5) cooling curing is carried out again;
6) demoulding;
In technique scheme, the part by weight between each component of described molding compound is as follows: resol: 100 parts; KH-550:1-2 part; Ethanol: 100 parts; Glass fibre: 100-150 part.
In technique scheme, in described step (1), the length of glass fibre is 12-30mm.
In technique scheme, in described step (1), bake out temperature is 70-80 DEG C, and drying time is 20-80min.
In technique scheme, in described step (4), molding time is 60-80min, and mold temperature is 175 ~ 180 DEG C.
In technique scheme, in described step (5), solidification value is 90-100 DEG C.
In technique scheme, the staple fibre in described step (2) is carbon fiber, whisker, fibrous magnesium silicate.
The invention has the beneficial effects as follows: owing to the addition of glass fibre in the process for preparation of molding compound, make same with thermosetting compound material intensity higher; Because strongthener adopts staple fibre, 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; Owing to adopting cooling curing after first carry out hot briquetting in compression molding process, under the dual function that a heat one is cold, make solidification effect better.
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;
Embodiment
Embodiment 1
Resol: KH-550: ethanol: the ratio of glass fibre=100:1:100:150 (weight ratio), carries out tearing pine after above-mentioned each component being stirred, then obtains molding compound dry 20min at temperature is 80 DEG C after.
Above-mentioned molding compound and carbon fiber are mixed to form mixture; Said mixture to be poured in the mould scribbling releasing agent at Heating temperature is 180 DEG C after heating and pressurizing 60min; At temperature is 100 DEG C, curing and demolding obtains same with thermosetting compound material again.
Embodiment 2
Resol: KH-550: ethanol: the ratio of glass fibre=100:2:100:100 (weight ratio), carries out tearing pine after above-mentioned each component being stirred, then obtains molding compound dry 80min at temperature is 70 DEG C after.
Above-mentioned molding compound and whisker are mixed to form mixture; Said mixture to be poured in the mould scribbling releasing agent at Heating temperature is 175 DEG C after heating and pressurizing 80min; At temperature is 90 DEG C, curing and demolding obtains same with thermosetting compound material again.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
