Embodiment 1

[0041] Embodiment 1 composite antibacterial agent preparation

[0042] The composite antibacterial agent is prepared by 10 parts by weight of chitosan, 1 part of dodecyltriphenylphosphonium chloride, 3 parts of bacterial cellulose, and 1 part of calcium chloride; specifically, the following steps Preparation: Bacterial cellulose is subjected to plasma treatment in an air atmosphere, the plasma voltage is 140V, the vacuum degree is 150Pa, the treatment time is 1-2min at room temperature, then dissolved in isopropanol solution, and quaternary phosphonium salt is added solution, stirred, cooled, washed and dried, then added calcium chloride and chitosan, uniformly dispersed and stirred for 30 minutes to obtain a composite antibacterial agent.

Embodiment 2

[0043] Embodiment 2 composite antibacterial agent preparation

[0044] Described composite antimicrobial agent is prepared by 12 parts of chitosan, 3 parts of tetradecyltriphenylphosphonium chloride, 10 parts of bacterial cellulose, and 1.2 parts of calcium chloride by weight parts; specifically by the following steps Preparation: Bacterial cellulose is subjected to plasma treatment in an air atmosphere, the plasma voltage is 140V, the vacuum degree is 150Pa, the treatment time is 1-2min at room temperature, then dissolved in isopropanol solution, and quaternary phosphonium salt is added solution, stirred, cooled, washed and dried, then added calcium chloride and chitosan, uniformly dispersed and stirred for 30 minutes to obtain a composite antibacterial agent.

Embodiment 3

[0045] Embodiment 3 composite antibacterial agent preparation

[0046] The composite antibacterial agent is prepared by 15 parts by weight of chitosan, 5 parts of cetyltriphenylphosphonium chloride, 15 parts of bacterial cellulose, and 1.5 parts of calcium chloride; specifically by the following steps Preparation: Bacterial cellulose is subjected to plasma treatment in an air atmosphere, the plasma voltage is 140V, the vacuum degree is 150Pa, the treatment time is 1-2min at room temperature, then dissolved in isopropanol solution, and quaternary phosphonium salt is added solution, stirred, cooled, washed and dried, then added calcium chloride and chitosan, uniformly dispersed and stirred for 30 minutes to obtain a composite antibacterial agent.

Abstract

The invention belongs to the technical field of modified polypropylene plastic and in particular relates to novel modified polypropylene plastic and a preparation method thereof. The polypropylene plastic is prepared from the following components in parts by weight: 100 to 150 parts of polypropylene, 10 to 20 parts of lignin, 5 to 10 parts of a compound antibacterial agent, 3 to 8 parts of a flame retardant, 5 to 10 parts of an antistatic agent, 3 to 8 parts of a dispersant and 3 to 8 parts of a cross-linking agent. The compound antibacterial agent is prepared through stirring and mixing bacterial cellulose subjected to plasma treatment, chitosan, quaternary phosphonium salt and calcium chloride. The novel modified polypropylene plastic provided by the invention has good thermal stability and mechanical properties and also has good antibacterial, antistatic, flame-retarding effects and the like; comprehensive performance of the novel modified polypropylene plastic is better than that of the existing common polypropylene plastic.

Description

technical field [0001] The invention relates to the technical field of modified polypropylene plastics, in particular to a preparation method of a novel modified polypropylene plastic. technical background [0002] With the expansion and deepening of market applications, polypropylene plastics are widely used in various industries. Therefore, the performance requirements for polypropylene are getting higher and higher, and single-function polypropylene plastics can no longer meet market demand. [0003] For example, some need to improve the heat-resistant temperature and mechanical properties of polypropylene to meet the requirements of good performance under high-temperature processing conditions; some polypropylene plastic products are used for food packaging, and it is necessary to ensure that the plastic does not contain toxic plasticizers Some polypropylene plastic products are used in the production of children's toys, and it is necessary to solve the problems of poor ...
