Description
Technical field
The present invention relates to a kind of method for quantitatively determining of plastic film wear resistance property.
Background technology
Evaluation to plastic film wear resistance property has very important significance, and the quality of film wearing quality directly influences its result of use on the packaging.The film that wears no resistance in the carrying of product external packaging process and packing material afterwards, the process that moves because friction can cause film surface to be ground flower, thereby the effect and the presentation quality of influence packing and then reduce the commodity value of packed article.
But, to the evaluation of film anti-wear performance, also there is not comparatively scientific quantitative bioassay standard at present, carry out paired observation after can only by rule of thumb two films being rubbed mutually, to judge its anti-wear performance.Owing to influenced by human factor, be difficult to provide objective and stable judge, therefore, the plastic sheeting producer and user are necessary to use a kind of standard, assay method objective and science to come the anti-wear performance of film is estimated.
Summary of the invention
Problem at above-mentioned prior art existence, the invention provides a kind of method for quantitatively determining of plastic film wear resistance property, so that the plastic sheeting producer and user carry out the evaluation of objective science to the anti-wear performance of plastic sheeting, the trouble of artificial test and the error of generation have also been avoided.
The present invention utilizes the performance of haze detection instrument and frictiograph test plastic sheeting friction resistant degree under defined terms, thereby sets up the method for quantitatively determining of film wearing quality.
One, definition:
1.1. mist degree: depart from the scatter light flux of incident light direction and the ratio of transmitted light flux through sample, represent with percentage.
1.2. anti-wear performance: injured bearing performance under the effect of friction force outside of the surface that refers to film.Represent with the variation of haze value that generally promptly film is through certain pressure, after the friction of speed and number of times, its haze value deducts the resulting difference of original haze value before the friction.The more little anti-wear performance of difference is good more, otherwise then poor more.
Two, reference to standard
GB2410-80 transparent plastic transmittance and mist degree test method.
The standard environment of GB2918-82 plastic sample status adjustment and test.
Three, determining instrument
3.1. haze detection instrument, model are B-121205801, Japanese TOYOSEIKI SEISAKUSHA company produces.Instrument should be tested and confirm Tt=100.0 ± 0.1%.Tt＝00.0％；HAZE＝00.0％。
3.2. printing ink frictiograph, model are 10-18-01-0002, U.S. TESTING MACHINES company produces.Abrading block adopts 4 pounds; Test speed: 85 times/minute; Cycle index: 20 times.
Four, condition determination
Temperature: 23 ± 2 ℃; Relative humidity: 50 ± 5%.
Five, assay method
In whole mensuration process, the testing sample surface cleaning be should guarantee, hand or other article contact measurement position forbidden.
5.1. prepare film sample to be measured.
5.2. according to GB GB2410, with the original haze value of mist degree instrument working sample, note is made A
0
5.3. narrow two side faces is stained with Double-face gummed paper on two sides narrow on the printing ink friction instrument friction table top and abrading block face.
5.4. it is original pattern that sample is cut into about 90.0mm * 230mm, 70mm * 140mm is the face sample, and the sample of having cut out sufficient amount is to guarantee that carrying out 5 times at least effectively measures.Original pattern and face sample go up most, next is opened and all can not be used for detecting.
5.5. get an original pattern, the film outside is adhered on the friction instrument friction table top outwardly, get a face sample, the film outside is adhered on the abrading block outwardly, start printing ink friction instrument and carry out outer external friction.
, after 20 times original pattern on the friction table top and the face sample on the abrading block are taken off 5.6. rub, change new original pattern and face sample in order to friction for the second time.
5.7. the face sample after the friction is cut into impartial three by the abrading block area, and light is watched, and chooses the most serious position of scratch, measures the sample multiple spot haze value of appearing with the mist degree instrument; The maximum haze value that record is this time measured.
Measure 5.8. each sample carries out 5 times, get the maximum haze value of each mensuration, ask its mean value, be haze value behind the mill of this sample, note is made A
2Mill back haze value deducts the preceding original haze value of friction, the mist degree difference before and after obtaining rubbing, and note is made A
1This difference is the quantitative evaluation index of film anti-wear performance, and the difference bright anti-wear performance of novel more is good more.
Six, the calculating of measurement result and expression:
A
1＝A
2-A
0
In the formula: A
1Mist degree difference before and after the friction of-film
Embodiment
Be described further below in conjunction with embodiment:
Use assay method provided by the invention that cigarette has been carried out practical measurement with the anti-wear performance of BOPP, resulting data are as shown in the table:
The table 1 cigarette wearing quality measurement result of BOPP
From measurement result as can be seen, the anti-wear performance of No. 9 samples is best; The anti-wear performance of No. 6 samples is the poorest; 4, the anti-wear performance of 7,8,10 samples is relatively good.This shows that by the quantitative measurement of this wearing quality, we can the quality quality to the BOPP wearing quality decision making in real work.
Method provided by the invention is applicable to Biaxially oriented polypropylene (BOPP), biaxially oriented polystyrene (BOPS), two-way stretching polyamide (BOPA), cast polypropylene (CPP) and polyester various plastic films such as (PET).
