Description
Technical field
The present invention relates to a kind of polymer matrix composite, particularly one kind (changes containing flexible tackifier coating
The dilute glue of property sealant) polymer matrix composite preparation method.
Background technology
In aeronautical product production, according to product design requirement, it is necessary to be pasted necessarily in aluminum alloy sheet material surface
Sub-assembly, which is made, in the material shell of shape and thickness is used for product.
Currently a popular process is that matrix material, paving are brushed after being surface-treated to aluminum alloy plate materials
Apply reinforcing material, solidification, finishing, inspection.But the toughness of common substrate material has certain limitation,
So during for occurring during use compared with large deformation, it is difficult to avoid aluminum alloy plate materials and material shell it
Between delamination splitting phenomenon occur, and then influence product service life and safety.
The content of the invention
The technical problem to be solved：
It is an object of the invention to provide a kind of polymerization for containing flexible tackifier coating (i.e. the dilute glue of Modified Sealants)
The preparation method of thing based composites, by using one kind, containing flexible tackifier coating, (i.e. Modified Sealants are dilute
Glue) polymer matrix composite, the adhesion improved between aluminum alloy plate materials and polymer matrix composite is strong
The problems such as degree is with toughness and bending crack.
Technical scheme：
What the present invention was realized in：
In XM-22B base cream, addition accounts for the F-44 epoxy resin of percentage by weight 8~10%, 6~8%11
Number vulcanizing agent, 0.1~0.6% No. 22 accelerator, lower rolls after being kneaded three times through three-roll grinder, as
Modified Sealants；Acetone, ethyl acetate, xylene solvent are mixed into (i.e. acetone, ethyl acetate, diformazan
The ratio between benzene is 1: 1: 1) as mixed solvent, is weighed with Modified Sealants and mixed solvent by 1: 1 one
Rise and stir, vulcanize 18~20 hours in the case of 20~30 DEG C, elastic tackifier coating is made；Then
Matrix material is brushed in the above, be plated in the reinforcing materials such as glass cloth, under vacuum conditions (vacuum 0.059~
0.088MPa) cold curing 24 hours, then release vacuum state cold curing solidification 24 in 12 days or 70 DEG C
Polymer matrix composite is made after hour.
The method being embodied on aluminum alloy plate materials is：
1st, the aluminum alloy sheet material surface after anodization is cleaned twice with industrial naptha, it is every all over hanging
10~20 minutes, then cleaned twice with acetone, it is every all over hanging 10~20 minutes.
2nd, bonding basecoat material is uniformly brushed after being hung 20 minutes to aluminum alloy sheet material surface, by bullet
Property tackifier coating is uniformly brushed on aluminum alloy plate materials.
3rd, cut out and lay the reinforcing materials such as glass cloth；
4th, room temperature vulcanization 18~20 hours；
5th, matrix material is brushed on the reinforcing materials such as glass cloth；
6th, cut out and lay the reinforcing materials such as glass cloth；
7th, the 5th, 6 procedures are repeated, until reaching the thickness of needs；
8th, (0.059~0.088MPa of vacuum) carries out room temperature solidification in 24 hours under vacuum conditions；
9th, vacuum state is released, room temperature solidify afterwards 12 days or 70 DEG C of solidify afterwards 24 hours；
10th, it is sub-assembly after trimming.
Beneficial effect：
With the polymer matrix composite that this method is made compared with existing polymer matrix composite, good toughness,
Adhesion strength is high, bending strength test when, the characteristic such as interface is not ftractureed；Specific data see the table below.
Embodiment
In XM-22B base cream, addition accounts for the F-44 epoxy resin of percentage by weight 8%, No. 6%11 vulcanizations
Agent, 0.5% No. 22 accelerator, lower roll, as Modified Sealants after being kneaded three times through three-roll grinder.
Pressed between Modified Sealants and mixed solvent (i.e. the ratio between acetone, ethyl acetate, dimethylbenzene are 1: 1: 1)
Weigh together and stir at 1: 1, vulcanizes 18~20 hours in the case of 20~30 DEG C, elasticity is made
Tackifier coating；
Aluminum alloy sheet material surface after anodization is cleaned twice with industrial naptha, it is every all over hanging 10~
20 minutes, then cleaned twice with acetone, it is every all over hanging 10~20 minutes；QS-7 bonding basecoat materials is equal
After even brushing is hung 20 minutes to aluminum alloy sheet material surface, elastic tackifier coating is uniformly brushed in aluminium
On sheet alloy；Cut out and lay the reinforcing materials such as glass cloth；Room temperature vulcanization 18~20 hours；In glass cloth
Deng brushing matrix material on reinforcing material；Cut out and lay the reinforcing materials such as glass cloth；Repetition is laid until reaching
To 1.6mm thickness；(0.059~0.088MPa of vacuum) carries out room temperature 24 hours under vacuum conditions
Solidification, then releases vacuum state, room temperature solidify afterwards 12 days or 70 DEG C of solidify afterwards 24 hours；Trimming shaping.
Aluminum alloy plate materials are used as with the polymer matrix composite of the present invention containing flexible tackifier coating
Reinforcing material, when good toughness, adhesion strength are high, bending strength is tested, interface is not ftractureed.
Polymer matrix composites are made with four kinds of techniques in following table, four kinds are made not using identical coating processes
With the polymer matrix composite of performance, different mechanical performances are obtained respectively.
