Embodiment 1

[0020] Example 1 Laminating machine cots

[0021] Such as figure 1 As shown, the present invention provides a plastic machine rubber roller, which comprises a metal roller core 1, a foamed rubber layer 2 made of a foamed rubber material, and a non-foamed rubber layer made of a non-foamed rubber material 3. The foamed rubber layer 2 is arranged outside the metal roller core 1, and the non-foamed rubber layer 3 is arranged outside the foamed rubber layer 2; the difference between the foamed rubber layer and the non-foamed rubber layer The thickness ratio is 1:2.

[0022] The rubber roller of the plastic laminating machine described in this embodiment uses the foamed rubber layer made of foamed rubber material as the "backing layer", and then uses the non-foamed rubber layer made of non-foamed rubber material to "cover", A composite material layer with a double-layer structure is formed, which can effectively avoid large volume changes when heated, and avoid large changes in th...

Embodiment 2

[0023] Embodiment 2 Preparation of rubber roller material for plastic machine

[0024] The rubber roller material of the plastic machine is non-foaming rubber material

[0025] The weight ratio of the non-foaming rubber material is: 225 parts of methyl vinyl silicone raw rubber; 112.5 parts of precipitated silica; 3.5 parts of hydroxyl silicone oil; 1.2 parts of hydrogen-containing silicone oil; 6.0 parts of dimethyl silicone oil; 3.5 parts of dimethyldiethoxysilane; 2.5 parts of internal release agent; 100 parts of silicon micropowder; 2.0 parts of 2,5-dimethyl-2,5-di-tert-butylperoxyhexane.

[0026] The preparation method of the non-foaming rubber material: methyl vinyl silicone raw rubber, precipitated silica, hydroxyl silicone oil, hydrogen-containing silicone oil, dimethyl silicone oil, dimethyldiethoxysilane, internal mold release agent , microsilica powder and 2,5-dimethyl-2,5-di-tert-butylperoxyhexane are placed in a double-roll mill and mixed evenly to obtain the non...

Embodiment 3

[0028] Embodiment 3 Preparation of rubber roller material for plastic machine

[0029] The rubber roller material of the plastic machine is non-foaming rubber material

[0030] The weight ratio of the non-foaming rubber material is: 225 parts of methyl vinyl silicone raw rubber; 112.5 parts of precipitated silica; 3.5 parts of hydroxyl silicone oil; 1.2 parts of hydrogen-containing silicone oil; 6.0 parts of dimethyl silicone oil; 3.5 parts of dimethyldiethoxysilane; 2.5 parts of internal mold release agent; 100 parts of modified silica powder; 2.0 parts of 2,5-dimethyl-2,5-di-tert-butylperoxyhexane;

[0031] The modified silicon micropowder is prepared by the following method: Soak the silicon micropowder in an aqueous solution containing polyethyleneimine with a molecular weight of 70,000 and polydimethyldiallyl ammonium chloride with a molecular weight of 300,000 for 12 hours. Dry to obtain the modified silica powder; the mass fraction of polyethyleneimine in the aqueous s...

Abstract

The invention belongs to the technical field of rubber rollers of laminator and rubber roller material preparation, and particularly discloses a rubber roller of a laminator and a rubber roller material of the laminator. The rubber roller of the laminator comprises a metal roller core, a foaming rubber layer made of a foaming rubber material and a non-foaming rubber layer made of a non-foaming rubber material, wherein the foaming rubber layer is arranged outside the metal roller core, and the non-foaming rubber layer is arranged outside the foaming rubber layer. According to the rubber rollerof the laminator, the foaming rubber layer made of the foaming rubber material is used as a substrate layer, and then the non-foaming rubber layer made of the non-foaming rubber material is used for coating, so that a composite material layer with a double-layer structure is formed; and the composite material layer can effectively avoid the large volume change during heating, and the contact pressure of the rubber roller of the laminator is prevented from being greatly changed, so that an excellent plastic packaging effect can be achieved through one-time roller passing.

Description

technical field [0001] The invention relates to the technical field of preparation of plastic machine rubber rollers and rubber roller materials, in particular to a plastic machine rubber roller and material for plastic machine rubber rollers. Background technique [0002] Laminating machine is also called plastic sealing machine or laminating machine or laminating machine, which is a special equipment for plastic sealing photos or documents. Its working principle is to place the items to be plastic-sealed in the middle of the plastic-sealed film, and then press them together through the high temperature and pressure of the rubber rollers of the plastic machine. The items after plastic sealing are beautiful and firm, and at the same time have functions such as waterproof, anti-scratch, anti-fouling, anti-wrinkle, anti-fading, etc., which can extend the shelf life. [0003] Laminating machine rubber roller is the core component of the laminating machine, and the quality of p...
