Abstract

The invention discloses a high-heat-insulation, ultraviolet-isolation and transparent colored master batch which comprises the following components in percentage by weight: 50-70% of resin, 0.5-10% of dispersing agent, 2-10% of heat-insulation ultraviolet-isolation nano material, 10-30% of slipping agent and 0-10% of coloring agent. The invention further discloses a preparation method of the high-heat-insulation, ultraviolet-isolation and transparent colored master batch. According to the master batch and the preparation method, the master batch and a transparent polyester chip are matched at a ratio, and subjected to extrusion and two-way stretch to produce a high-heat-insulation, ultraviolet-isolation and transparent colored film; the high-heat-insulation, ultraviolet-isolation and transparent colored film has excellent heat-insulation and ultraviolet-isolation functions; the heat-insulation and ultraviolet-isolation capacity can be adjusted as required; the color is uniform and consistent; and when the master batch is applied to PET (polyethylene glycol terephthalate) film extrusion or sheet extrusion, the master batch is smog-free, high in transparency and good in smooth effect.

Example Embodiment

[0023] Example 1: Masterbatch ingredients are shown in Table 1.

[0024]

[0025] 1) Under normal temperature and pressure, in the high-speed mixer, turn on the stirring blade and control the speed to 600r/min, and the heating and mixing temperature to be 85°C;

[0026] 2) After weighing the materials according to the ingredients list, put in 50% of the total amount of PET resin, and then put in the other components according to the proportion of ingredients. After the materials are mixed for 10 minutes, ensure that the slip agent has been completely melted and the materials are formed. Block, add the remaining PET resin after cooling;

[0027] 3) Then control the mixer speed to 480r/min to disperse the materials into granules to complete the preliminary melting and mixing of the materials, and the dispersing time is 1h;

[0028] 4) Put the preliminarily melted and mixed materials into the twin-screw machine for further melting and blending. The melting temperature is controlled at 260℃, the screw speed is 100r/min, and the time is 1h. The shearing and mixing of the screw makes the additives in The carrier resin is thoroughly dispersed uniformly, and then granulated and dried to obtain a transparent colored masterbatch with high heat insulation and ultraviolet radiation.

[0029] The natural color masterbatch can be combined with other heat-insulating UV-cut masterbatches to produce heat-insulating and UV-cutting functional films in appropriate proportions with transparent polyester chips. It is mainly used to adjust the smoothness of the film product and also adjust the color and heat insulation ability of ultraviolet rays.

[0030] Example 2: See Table 2 for the ingredients of the masterbatch.

[0031]

[0032] 1) Under normal temperature and pressure, in the high-speed mixer, turn on the stirring paddle and control the speed to 1000r/min, and the heating and mixing temperature to be 100℃;

[0033] 2) After weighing the materials according to the ingredients list, first put in 50% of the total amount of PET resin, and then put in the other components according to the proportion of the ingredients, and wait for the materials to mix for 15 minutes to ensure that the slip agent has been completely melted and the materials are consolidated Block, add the remaining PET resin after cooling;

[0034] 3) Then control the mixer speed to be 250r/min to disperse the materials into granules to complete the preliminary melting and mixing of the materials, and the dispersing time is 10h;

[0035] 4) Put the preliminarily melted and mixed materials into the twin-screw machine for further melting and blending. The melting temperature is controlled at 255℃, the screw speed is 300r/min, and the time is 5h. Through the shearing and mixing of the screw, the additives are The carrier resin is thoroughly dispersed uniformly, and then granulated and dried to obtain a transparent colored masterbatch with high heat insulation and ultraviolet radiation.

[0036] Use heat-insulating UV-cut transparent blue-green masterbatch and transparent polyester chips to produce heat-insulating and UV-cut functional films according to product needs. If it is necessary to adjust the smoothness of the film product, the UV-cut transparent natural color masterbatch of Example 1 can be appropriately added. With this masterbatch, it is possible to produce a heat-insulating film with high light transmittance, high heat insulation and UV cut with a light transmittance of more than 70%, an infrared cut of more than 80%, and an ultraviolet cut of more than 99%. It is suitable for architectural glass and automobile front glass that require high light transmission, high heat insulation and UV protection.

The melting temperature is controlled at 270℃, the screw speed is 200r/min, and the time is 3h. Through the shearing and mixing of the screw, the additives are The carrier resin is thoroughly dispersed uniformly, and then granulated and dried to obtain a transparent colored masterbatch with high heat insulation and ultraviolet radiation.

[0043] The heat-insulating UV-cut transparent light yellow-green masterbatch and transparent polyester chips are used to produce heat-insulating and UV-cut functional films according to product requirements. If it is necessary to adjust the smoothness of the film product, the UV-cut transparent natural color masterbatch of Example 1 can be appropriately added. With this masterbatch, it is possible to produce a heat-insulating film with high light transmittance, high heat insulation and UV cut with a light transmittance of more than 80%, an infrared cut of more than 80%, and an ultraviolet cut of more than 99%.
