Abstract

The invention relates to the field of plastic container preparation, and discloses a polypropylene bottle for cosmetics and a preparation method thereof, which is prepared from the following raw materials in parts by weight: 80-120 parts of polypropylene, 10-30 parts of propylene glycol, and 2 parts of carboxymethyl cellulose -4 parts, 6-8 parts of antibacterial agent, 2-4 parts of plasticizer, 2-4 parts of toughening agent, 2-4 parts of antioxidant, 4-6 parts of lubricant, 2-4 parts of light blocking agent. Preparation method: 1), weigh each raw material separately and add the raw materials into the reaction kettle for mixing, stirring, heating and melting; 2), extrude the melted raw materials through an extruder; 3), extrude the extruded The raw material is injected into the embryo by the injection molding machine; 4), the embryo is blown, stretched, cooled, internally cooled, discarded and pressure-holding, and then bottled; 5) The finished product is obtained after debottle removal. On the basis of good strength, the polypropylene bottle for cosmetics of the present invention has antibacterial function and long antibacterial effect.

Description

technical field [0001] The invention relates to the field of plastic container preparation, in particular to a polypropylene bottle for cosmetics and a preparation method thereof. Background technique [0002] Because plastic bottles are light in weight, easy to process, and have low manufacturing costs, plastic bottles have been widely used as product containers in the fields of food and beverages, daily necessities, and the like. However, in daily life, pathogenic microorganisms such as bacteria are ubiquitous, and many products are easily contaminated during storage. If people's human body comes into contact with plastic bottles when using products, they are easy to be infected with bacteria, thereby threatening human health. [0003] The Chinese patent application number CN201510550180.5 discloses an environmentally friendly plastic bottle and its preparation method, wherein, in parts by mass, the environmentally friendly plastic bottle is made of the following component...
