Embodiment 1～3

[0031] The performance test is as follows:

[0032]

Embodiment 4

[0034] A method for preparing a BOPP film with controllable matting and haze distribution of low gloss, comprising the following process steps: taking 40 parts of special polypropylene for BOPP, 40 parts of matting agent, 10 parts of antistatic agent erucamide, and antiblocking agent silicon dioxide 10 parts; after accurate weighing, mix polypropylene and other additives in a high-speed mixer in order for 30 minutes, and then blend in a single-screw extruder, stretch longitudinally, and transversely to obtain the product. The extruder temperature is controlled at 200-270°C, and the screw speed is controlled at 30-50r / min. The obtained low-gloss matting film is coated and glued, then compounded with the cloth textile material, and then dried, the film is peeled off, and the matting effect can be transferred to the cloth textile.

Embodiment 5

[0036] A preparation method of BOPP film with controllable matting and haze distribution of low gloss, comprising the following process steps: take 90 parts of special polypropylene for BOPP, 8 parts of matting agent, 1 part of antistatic agent ethoxylamine, and 1 part of antiblocking agent PMMA After accurate weighing, put polypropylene and other additives into a high-speed mixer and mix for 30 minutes, and then blend through a single-screw extruder, stretch longitudinally, and transversely to obtain the product. The extruder temperature is controlled at 200-270°C, and the screw speed is controlled at 30-50r / min. The obtained low-gloss matting film is coated and glued, then compounded with the cloth textile material, and then dried, the film is peeled off, and the matting effect can be transferred to the cloth textile.

Abstract

The invention belongs to the technical field of novel materials and particularly relates to a low-glossiness extinction haze distribution controllable biaxially-oriented polypropylene (BOPP) film, which is characterized by comprising the following ingredients (in percentage by weight): 40 to 90 percent of polypropylene, 1 to 40 percent of extinction agents, 0 to 30 percent of anti-static agents and 0.5 to 30 percent of anti-sticking agents. A preparation method of the BOPP film comprises the following steps that: the ingredients are mixed for 30 minutes in a high-speed mixing machine according to the recipe proportion, and then, products are obtained through single-screw extruding machine fusion, vertical stretching and transverse stretching, ,wherein the process temperature of the single-screw extrusion is 200 to 270 DEG C, and the screw rotating speed is controlled at 30 to 50r / min. The products have the advantages that the film haze can be regulated and controlled, and the extinction effect can also be transferred to textiles, leather and gold and silver card paper materials.

Description

technical field [0001] The invention belongs to the technical field of new materials, in particular to a BOPP film with low gloss and controllable extinction haze distribution and a preparation method thereof, in particular to a BOPP film which can transfer the extinction effect to textiles, leather and gold and silver cardboard and its preparation method. Background technique [0002] Low-gloss matte BOPP film has low gloss, diffuse reflection, and soft eye feeling. It has the characteristics of good cost performance, easy access to raw materials, and stable product quality. It is also easy to make films through antistatic, adhesion, or other polymer blends. Therefore, BOPP films made of polypropylene have been widely used in various fields for a long time. [0003] The fly in the ointment is that due to the relationship between the addition of matting agent, the existing matting film has many bright spots on the surface, poor gloss, unsatisfactory matting effect, and the ...
