Abstract
The present invention relates to the heatproof method of testing of a kind of sunlight-type fluorescent pigment, comprise the steps: to mix polypropylene particles, sunlight-type fluorescent pigment, titanium dioxide, white oil by a certain percentage to shake up；Using injection machine with 190 DEG C of injection mo(u)lding plastic plates, it is thus achieved that one piece of plastic cement sample panel, the temperature then raising injection machine continues injection, often raises 10 DEG C of injections once, and corresponding each plastic cement sample panel obtaining a formation of lots, until temperature is raised to 300 DEG C；After terminating Deng injection, all of plastic cement sample panel is contrasted, analyzed the chromatic aberration of plastic cement sample panel by range estimation and colour photometer, find the point of high-temperature resistant of fluorescent pigment, range estimation judges without obvious aberration, again with colour photometer colour examining DE≤3, intensity >=96, temperature now is exactly high-temperature resistant point.The method of testing that the present invention provides is the most easy to operate, and temperature tolerance accuracy is high, can effectively judge that can the heat resistance of sunlight-type fluorescent pigment reach requirement.
Description
Technical field
The present invention relates to sunlight-type fluorescent pigment performance measurement method field, specifically, relate to a kind of daylight type fluorescence
The assay method of pigment heat resistance.
Background technology
At present, the heatproof test of sunlight-type fluorescent pigment routine has two kinds, and one is that sunlight-type fluorescent pigment is added thing
In the mixed solution first prepared, after being stirred by homogenizer, in the way of manually drawing color on cloth uniformly on
Color, is then placed in baking oven, toasts in different temperature, has unchanged by colour photometer detection color, analyzes the highest
Resistance to warm spot, the standard sample needed due to this method is more, and is all manually colouring, and error is relatively big, and the required time is also
Longer.Another kind of heatproof method of testing is to be placed on sunlight-type fluorescent pigment in baking oven to dry certain time at different temperature,
Form plastic plate by injection machine the most again, become by the color of the plastic plate under range estimation and Computer color testing instrument test different temperatures
Change situation, finds high-temperature resistant point, due to this method be in the case of sunlight-type fluorescent pigment does not has the protection of carrier just
Enter baking oven to toast, easily by the fluorescence property of high temperature sunlight-type fluorescent pigment, the method for the most this test with under
The detection of trip product easily produces bigger error, is unfavorable for and the communication of downstream client.
Therefore, there is further improvement and optimize demand in the heatproof method of testing for sunlight-type fluorescent pigment, this is also
It is one of the study hotspot in this technical field and emphasis, the present invention is accomplished especially power and starting point place.
Summary of the invention
For the above-mentioned technical problem overcoming prior art to exist, the present inventor carried out substantial amounts of further investigation it
After, thus complete the present invention.
The present invention is achieved through the following technical solutions, and the heatproof in particular to a kind of sunlight-type fluorescent pigment is tested
Method, comprises the steps:
Step one, by polypropylene particles, sunlight-type fluorescent pigment, titanium dioxide, white oil by a certain percentage re-pack in bag mixed
Conjunction shakes up, and is as the criterion with the surrounding not bread of sack；
Step 2, uses injection machine with 190 DEG C of injection mo(u)lding plastic plates, it is thus achieved that one piece of plastic cement sample panel, then raises note
The temperature of molding machine continues injection, often raises 10 DEG C of injections once, and corresponding each plastic cement sample panel obtaining a formation of lots, until temperature
Till degree is raised to 300 DEG C；
Step 3, contrasts all of plastic cement sample panel after waiting injection to terminate, and is moulded by range estimation and colour photometer analysis
The chromatic aberration of glue sample panel, finds the point of high-temperature resistant of fluorescent pigment, range estimation to judge without obvious aberration, then use colour photometer colour examining
DE≤3, intensity >=96, temperature now is exactly high-temperature resistant point.
Preferably, described polypropylene particles, sunlight-type fluorescent pigment, titanium dioxide, the weight ratio of white oil are 1000: 4: 2:
1.6。
Preferably, when being molded at high-temperature resistant point, after previous piece of plastic cement sample panel of required plastic plate obtains, should stop
Only injection, allows injection compound stop in injection machine 5 minutes, and injection mo(u)lding obtains required plastic plate the most again.
Compared with prior art, beneficial effects of the present invention is as follows: the present invention is by by a certain amount of daylight type fluorescence face
Material adds to and is sufficiently mixed uniformly in polypropylene particles, after through injection machine injection mo(u)lding plastic plate at different temperature, logical
Cross the color situation of change of plastic plate under range estimation and Computer color testing instrument test judgement different temperatures, analyze high-temperature resistant point, resistance to
Warm nature accuracy is high, easy to operate, is possible not only to effectively judge that can the heat resistance of sunlight-type fluorescent pigment reach requirement,
And it is also applied for the detection of downstream product.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this area
Personnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement.These broadly fall into the present invention
Protection domain.
The heatproof method of testing of a kind of sunlight-type fluorescent pigment, is made up of following steps:
Step one, the preparation of compound: by sunlight-type fluorescent pigment 0.4g, titanium dioxide 0.2g, polypropylene particles 100g, white
Oil 0.16g is contained in the bag that re-packs mixing and shakes up, and is as the criterion with the surrounding not bread of sack；
Step 2, uses injection machine with 190 DEG C of injection mo(u)lding plastic plates, it is thus achieved that one piece of plastic cement sample panel, then raises note
The temperature of molding machine continues injection, often raises 10 DEG C of injections once, and corresponding each plastic cement sample panel obtaining a formation of lots, until temperature
Till degree is raised to 300 DEG C；
Step 3, contrasts all of plastic cement sample panel after waiting injection to terminate, and is moulded by range estimation and colour photometer analysis
The chromatic aberration of glue sample panel, finds the point of high-temperature resistant of fluorescent pigment, range estimation to judge without obvious aberration, then use colour photometer colour examining
DE≤3, intensity >=96, temperature now is exactly high-temperature resistant point, when being molded at high-temperature resistant point, before required plastic plate
After one piece of plastic cement sample panel obtains, injection should be stopped, allowing injection compound stop in injection machine 5 minutes, be molded into the most again
Type obtains required plastic plate.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformation or amendment within the scope of the claims, this not shadow
Ring the flesh and blood of the present invention.
