Abstract
During present invention illustrates determining 180 ° of peeling strength tests of sealant after a kind of hot air aging, a kind of simple and easy method prepared by 180 ° of peel strength samples.By using the sealant of dilution as protective coating so that according to HB5249 1993《180 ° of peeling strength test methods of room temperature vulcanization sealant》180 ° of peel strength samples of sealant of preparation are will not aging embrittlement after hot air aging so that waste sample ratio is reduced.
Description
Technical field
The present invention relates to a kind of preparation method of fluid sealant performance test sample, the method that particularly prepared by 180 ° of peel strength samples of vulcanized sealant.
Background technology
To investigate 180 ° of peel strength performances of fluid sealant, it is necessary to press HB 5249-1993《180 ° of peeling strength test methods of room temperature vulcanization fluid sealant》Prepare 180 ° of peel strength samples of fluid sealant.
HB 5249-1993《180 ° of peeling strength test methods of room temperature vulcanization fluid sealant》, prepared by sample gives one set of die, the mould is made up of three parts：Lower template, cope plate, fastener.Its sample manufacturing process is made up of ten steps：The first step, cleans and dries test piece；Second step, prepares and handles canvas；3rd step, test piece is put into lower template groove；4th step, scratches the fluid sealant just mixed in test piece, and edge strikes off along along groove；5th step, fluid sealant is applied in canvas one end, and coating length is no less than 100 ㎜；6th step, canvas is fitted with test piece coated face, side by side bubble removing；7th step, assembles cope plate, firmly screwing bolts；8th step, the fluid sealant just mixed is scratched with scraper, edge strikes off along along groove in canvas；9th step, parks and is taken out after 24h；Tenth step, vulcanization.In actual tests operation, the sample prepared in this way is after high temperature ageing, because exposed canvas passes through prolonged hot air aging embrittlement, when carrying out peel strength test, canvas is often broken in advance, cause waste sample, and be possible to because waste sample excessively caused by test failure and reviewed, and then extend the test period.
The content of the invention
(1) goal of the invention：To ensure that canvas is not broken in advance because of aging embrittlement in sample, waste sample, guarantee test cycle are reduced, spy proposes a kind of 180 ° of peel strength preparation method of sample of fluid sealant.
(2) technical scheme：
There is provided a kind of 180 ° of peel strength preparation method of sample of fluid sealant, comprise the following steps：Step one, clean and dry test piece；Step 2, cleans canvas and smooth reduction is appropriate size；Step 3, test piece is put into lower template groove；Step 4, scratches fluid sealant in test piece, and edge strikes off along along groove；Step 5, the fluid sealant is applied in one end of canvas, and coating length is no less than 100 ㎜；Step 6, one end of canvas is fitted with test piece coated face, side by side bubble removing；Step 7, assembles cope plate, firmly screws the bolt of upper and lower template；Step 8, described fluid sealant is scratched with scraper in canvas, and edge strikes off along along groove, and parks taking-up after 24 hours；Step 9, coated fluid sealant is diluted, and the fluid sealant with hairbrush after the other end coating dilution of canvas；Step 10, it is to be diluted after fluid sealant park to not glue the phase after all fluid sealants are vulcanized.
(3) beneficial effects of the present invention：
Compared with existing 180 ° of peel strength preparation method of sample of fluid sealant, the beneficial effect of invention is：Brushed with the similar fluid sealant after the dilution being had no adverse reaction with fluid sealant in non-waterproof sheet surface, form protective layer and completely cut off hot-air and contacted with canvas, make canvas not because with hot air aging embrittlement, reduce waste sample ratio, ensure that the test period.
Specific embodiment
With reference to specific embodiment, the method for further illustrating the present invention.In the experiment using 180 ° of peel strength method test fluid sealant heat-resistant air aging properties of XM28- I, XM28- I fluid sealant, 180 ° of peel strength samples need to be prepared.Its implementation is as follows：
A kind of 180 ° of peel strength preparation method of sample of fluid sealant,
Step one, clean and dry test piece；Step 2, cleans canvas and smooth reduction is appropriate size；Step 3, test piece is put into lower template groove；Step 4, scratches fluid sealant in test piece, and edge strikes off along along groove；Step 5, the fluid sealant is applied in one end of canvas, and coating length is no less than 100 ㎜；Step 6, one end of canvas is fitted with test piece coated face, side by side bubble removing；Step 7, assembles cope plate, firmly screws the bolt of upper and lower template；Step 8, described fluid sealant is scratched with scraper in canvas, and edge strikes off along along groove, and parks taking-up after 24 hours；Step 9, coated fluid sealant is diluted, and the fluid sealant with hairbrush after the other end coating dilution of canvas；Step 10, it is to be diluted after fluid sealant park to not glue the phase after all fluid sealants are vulcanized.
Further：In step one, acetone is dipped in cotton balls and cleans LY12-CZ Anodising aluminium alloys test piece three times, and dries 20min.
Further：In step 2, canvas size is the ㎜ of 230 ㎜ × 95.
Further：Described fluid sealant is XM28 polysulfide sealants.
Further：The solvent for diluting the fluid sealant is acetone.
