Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings so as to facilitate the further understanding of the present invention by those skilled in the art, and do not constitute a limitation to the right thereof.
Referring to fig. 1, a test sample plate for testing transparent UV electron gluing agent hardness, this test sample plate includes model plate body 1, and the hardness of model plate body 1 is greater than 1H, and the transparency of model plate body 1 is greater than 89%, and the one side of model plate body 1 sets up to experimental face, and experimental face all is provided with scale 2 around the board edge of model plate body 1. The sample plate body 1 is moderate in hardness and thickness, high in transparency, accurate in scale on the periphery and convenient for smearing the transparent UV electronic adhesive, and after the transparent UV electronic adhesive is completely cured to form a coating, a hardness test is completed by using a hand-operated pencil hardness tester; when observing the mar, erect model body 1, face the light source, the damaged condition of scribbling can be observed clearly, and when the recognition degree of difficulty is great, the position of every mar of contrast record (the position of every mar has been recorded according to scale 2 during the mar), also can carefully discern, and is swift convenient, the strong operability.
Sample plate body 1 is the cuboid form, both is convenient for fix to outside test platform on, makes things convenient for smearing of transparent UV electron gluing agent again to can carry out reliable scratch test.
The sample body has a length of 8-12cm, a width of 6-10cm and a thickness of 0.5-1.5mm, and preferably, the sample plate body 1 has a length of 9.5cm, a width of 8.5cm and a thickness of 1 mm.
The division value of the graduated scale 2 is 1mm, the accuracy is high, the position of the scratch can be conveniently recorded, and the length of the scratch can be conveniently measured.
And a groove 3 convenient for smearing the transparent UV electronic adhesive is also arranged on the test surface. The shape of the groove 3 is consistent with that of the sample body, and the groove is cuboid, so that the fixing and the testing are convenient.
The depth of the groove 3 is 0.1-0.3mm, preferably, the depth of the groove 3 is 0.2mm, so that the transparent UV electronic adhesive can be conveniently and uniformly coated on a test surface, and a scratch test can be conveniently carried out.
The sample plate body 1 is a PC plate, preferably, the sample plate body 1 is a PC sunlight plate, namely a polycarbonate sunlight plate, a polycarbonate hollow plate, a glass kapron plate, a polycarbonate plate and the like, is processed by high-performance engineering plastic polycarbonate resin, has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame resistance, ageing resistance and the like, has the greatest characteristic of high transparency and high hardness, and can well meet the test requirements.

firstly, coating a transparent UV electronic adhesive on a PC board which is moderate in hardness and thickness, high in transparency and precise in scale on the periphery, after the PC board is completely cured, placing and fixing the PC board with a test surface facing upwards, strongly scratching a pencil at an angle of 45 degrees with the test surface without breaking a lead core, scratching the front of a tester at a constant speed to about lcm, wherein the scratching speed is 1cm/s, recording the position of the scratch after once scratching, re-grinding the tip of the lead core, repeatedly carrying out the test for 5 times by using the pencil with the same hardness mark, taking down the PC board, erecting the PC board, facing the PC board, clearly observing the damage condition of a coating film, and when the difficulty in identification is high, carefully identifying the position of each scratch recorded by contrasting; when only 2 or less tests of 5 tests can see the substrate or the primer coating, the same test is carried out by using a pencil with a hardness mark larger by one, when the damage of the coating reaches more than 2 times (every 5 tests are carried out), the hardness mark of the pencil at the moment can be read, the hardness mark of the pencil at the next position of the hardness mark of the pencil is recorded, the hardness of the pencil is the hardness of the tested coating, and the hardness of the pencil is tested one by one from the hardest pencil to the softest pencil until the pencil with the coating not scratched is found.
The pencil used in the test process refers to a hand-operated pencil hardness tester in the prior art and consists of a tester body, rollers, an HB pencil and a fastening screw, wherein the pencil hardness tester is in three-point contact with a tested surface (two-point rollers, one point is a pencil lead), the included angle between the pencil and the tested surface is always ensured to be 45 degrees, and the pressure of the hardness tester body on the pencil lead is ensured to be (1 +/-0.05) kg according to a lever principle;
the hand-operated pencil hardness tester is designed and manufactured according to GB/T6739, the coating surface is opposite to another object with larger hardness acted on the coating surface, namely the resistance of a paint film to deformation is measured, the pencil mark is used for representing the resistance of the paint film, the test method is suitable for testing the hardness of a coating, is a simple and rapid coating hardness test method, and the sharp edge of the pencil is used for scratching the surface of the coating, so that the hardness of the coating is tested;
testing indexes are as follows: according to the industrial standard, the hardness of the pencil lead is divided into 13 grades, and the hardness gradually decreases from the hardest 6H to 5H, 4H, 3H and 2H, H, then to HB with moderate hardness, and then to the softest 6B from B and 2B. Wherein H represents hardness (hardness), B represents blackness (black), hardness decreases from 6H to 6B, and pencil color becomes darker. The shade of the color is related to the graphite content, and the darker the color, the higher the graphite content, and the softer the pencil.
