Embodiment 1

[0027] This embodiment provides an easy-to-form polypropylene for blisters. The composition ratio of main raw materials includes: antioxidant 1010 is 450ppm, antioxidant 168 is 500ppm, acid absorbing agent is 350ppm, slip agent is 150ppm, transparent The nucleating agent is 3500ppm, and polypropylene is the balance; wherein the amount of each raw material added is optimized based on the total amount of raw materials added.

[0028] Then the preparation method step of the polypropylene of above-mentioned raw material is:

[0029] Step 1: Feeding, put the raw materials in the loading box;

[0030] Step 2: Pass the material in the above-mentioned material frame through the air conveyor, enter the extrusion plasticization, and after being extruded through the die, it is sequentially extruded by three rollers, wherein the speed of the fixed roller is controlled at 24.32m / min, and the fixed roller The temperature is 40°C, the speed of the pressing roller is 24.54m / min, the temperat...

Embodiment 2

[0034] This embodiment is different from Embodiment 1 in that the raw material composition of the polypropylene for the blister is different, and the rest are the same as in Embodiment 1.

[0035] This embodiment 2 provides an easy-to-form polypropylene for blisters. The composition ratio of the main raw materials includes: 550ppm for antioxidant 1010, 1500ppm for antioxidant 168, 450ppm for acid absorbing agent, 250ppm for slip agent, transparent The nucleating agent is 4500ppm, and the polypropylene is the balance; wherein the amount of each raw material added is optimized based on the total amount of raw materials added.

Embodiment 3

[0037] This embodiment is different from Embodiment 1 in that the raw material composition of the polypropylene for the blister is different, and the rest are the same as in Embodiment 1.

[0038] This embodiment 3 provides an easy-to-form polypropylene for blisters. The main raw material composition ratio includes: antioxidant 1010 is 500ppm, antioxidant 168 is 1000ppm, acid absorbing agent is 400ppm, slip agent is 200ppm, transparent The nucleating agent is 4000ppm, and polypropylene is the balance; wherein the amount of each raw material added is optimized based on the total amount of raw materials added.

Abstract

The invention discloses easy-to-form polypropylene for a bubble cap and a preparation method of the easy-to-form polypropylene, which solve the problems that the existing polypropylene for the bubble cap is difficult to form and poor in transparency, and the preparation effect of the bubble cap is influenced. The invention relates to easy-to-form polypropylene for a bubble cap. The easy-to-form polypropylene for the bubble cap is prepared from the following main raw materials: 450 ppm to 550 ppm of an antioxidant 1010, 500 ppm to 1500 ppm of an antioxidant 168, 350 ppm to 450 ppm of an acid acceptor, 150 ppm to 250 ppm of a slipping agent, 3500 ppm to 4500 ppm of a transparent nucleating agent and the balance of polypropylene. The method has the advantages that the hardness and transparency of the polypropylene material are improved, and the bubble cap is easy to form, not easy to crack, good in transparency and the like.

Description

technical field [0001] The invention relates to the technical field of blister forming, in particular to an easy-to-form polypropylene for blisters and a preparation method thereof. Background technique [0002] The use of blisters to package medicines is an important form of pharmaceutical packaging. Therefore, the quality of blister molding is extremely important to pharmaceutical packaging companies. The current blisters are formed by blister or blow molding. In the current process, polyvinyl chloride is generally selected as the molding material in order to meet the needs of different shapes of drug blister molding, mainly because polyvinyl chloride has good transparency and barrier properties, and is easy to form blisters. [0003] However, in order to improve the molding and processing of polyvinyl chloride, plasticizers are generally added to polyvinyl chloride. At present, the most used plasticizers are phthalates, which will cause safety risks to the body when they ...
