Verification examples
In this verification example, the apparent viscosity (thin consistency), softening point, appearance detection and steel plate peel strength detection (test results are shown in table 1) are performed on the back glue of the environment-friendly PVC floors provided in the first to third embodiments, and the following methods are adopted:
1. viscosity of the oil
Viscosity is a viscous property of liquid which generates internal friction between molecules when flowing, and the viscosity is expressed by viscosity and is used for characterizing a resistance factor related to the liquid property. The unit is Pa.s, and the characteristic is that the area of the two blocks is 1m2Board (2)The liquid is immersed in the liquid at a distance of 1m, and when a shear stress of 1N is applied to the liquid so that the relative velocity between the two plates becomes 1 m/sec, the viscosity of the liquid becomes 1 pas, and 1 pas is 1000 mPas is 1000 cps.
The apparent viscosity was measured using a Brookfield (or same grade) viscometer as follows:
(1) sample preparation: an environment-friendly PVC floor gum sample with the weight of 10.5g +0.5g is taken.
(2) The method comprises the following operation steps:
I) selecting the related setting of the No. 27 rotor, and setting the temperature to be 180 ℃;
selecting a proper same rotor for the same sample and putting the weighed sample into a sample groove;
II) after the temperature reaches 180 ℃, vertically immersing the rotor into the central part of the sample, and enabling the liquid level to reach a rotor liquid level marking (a protection frame is arranged);
III) starting a rotational viscometer, and adjusting the rotating speed according to the actual viscosity change to ensure that the reading on the display screen can test the viscosity data within the range of 20-80% under the current rotating speed condition;
IV) reading when the value of the display screen is kept unchanged to obtain the viscosity data of the product;
v) three determinations per sample.
2. Softening point
The softening point is not the melting point, the softening point is not the phase transition process, it is the process by which the polymer decreases from a high viscosity to a specific viscosity, the softening point being characterized by a temperature range. In the hot melt adhesive industry, the softening point test method generally adopts a ring and ball method for testing. The specific test steps are as follows:
I) melting the rubber sample to be detected and filling the rubber sample into the sample ring;
II) scraping off excessive samples on the sample ring by using a scraper so that the samples are flush with the ring surface;
III) cooling the sample for 24 hours at room temperature;
IV) then placing a sample ring filled with the sample, a steel ball positioning ring and a steel ball on the metal bracket in sequence;
v) placing the metal bracket in a glycerol bath with the heating rate of 5 ℃/min;
VI) opening the automatic softening point tester, and starting stirring;
VII) along with the rise of the temperature of the glycerol, the sample begins to soften until the softening point data is automatically recorded by an instrument in the process that the steel ball falls to the lower bearing plate;
VIII) printing the test result;
IX) test results of the final softening point were averaged over 3 samples.
3. Appearance detection
The method mainly adopts a mode of establishing standard sample comparison by visual inspection, samples with the same packaging specification are compared in color and transparency, and the standard sample needs to be established for the first production.
4. Steel plate peel strength test
1) After the back glue of the environment-friendly PVC floor is heated and melted, the back glue is coated on the PVC floor by a coating machine and coated with release paper, wherein the coating amount is controlled to be 20-80g/m2。
2) After the compounding is finished, the peel strength of the composite steel plate to a standard steel plate is tested.
Table 1 test results of related indexes of the environmental PVC floor back glue provided in the first to third embodiments
As can be seen from Table 1, the PVC floor backadhesives of examples 1-3 are yellow translucent viscous solids with viscosities of 4000-.
