Description

Functional master batch applicable to thin-wall high-length-diameter-ratio polypropylene ribbon as well as preparation method and application thereof
Technical Field
The invention belongs to the technical field of polymer materials and processing, and particularly relates to a thin-wall high-length-diameter-ratio plastic product, in particular to a functional master batch suitable for a thin-wall high-length-diameter-ratio polypropylene ribbon, and a preparation method and application thereof.
Background
Thin-wall plastic molding technology is a relative concept, and the definitions in the industry are generally divided into three cases:
(1) Injection molding with the ratio L/T of flow length to thickness being more than 100 or 150 is thin-wall high-length-diameter-ratio injection molding, L is the flow length from the melt entering the mold to the furthest point of the cavity which the melt must fill, and T is the corresponding average wall thickness;
(2) The thickness of the molded plastic part is less than 1mm, and the projection area of the molded plastic part is 50cm 2 The above injection molding method;
(3) The wall thickness of the molded plastic part is less than 1mm (or 1.5 mm), or the injection molding of t/d (plastic part thickness t, plastic part diameter d, for disc type plastic part) below 0.05 is defined as thin-wall injection molding.
At present, the domestic thin-wall plastic molding technology is applied to the fields of food containers, medicine boxes, cosmetics, stationery and the like, and belongs to injection molding with small thin-wall length-diameter ratio. In the aspect of thin-wall high-length-diameter-ratio injection molding, because of the thin-wall high-length-diameter-ratio injection molding technology, higher requirements are put forward on equipment and an injection molding process, and meanwhile, higher requirements are put forward on high fluidity of raw materials, while the thin-wall low-length-diameter-ratio injection molding has lower fluidity requirements on the raw materials.
Polypropylene is a thermoplastic resin prepared by propylene polymerization, and has excellent mechanical property, good heat resistance, excellent stress cracking resistance and rigidity, easy processing and molding and wide application value. Polypropylene as the fastest growing variety of general thermoplastic plastics is increasingly important in economic construction and people's life, and has wide application in the fields of automobile industry, household appliances, electronics, packaging, building materials, furniture and the like.
Thin-walled high aspect ratio articles are an important class of applications in plastics applications, where the more typical article is a tie. The ribbon is used as a line product, is extremely widely applied to the production and life of the national, and particularly is popularized in the civil and building industries, and the demand of the ribbon is increased year by year at a rate of 12-15%. At present, more than 90% of the bandages on the market are nylon products, and compared with polypropylene, nylon has the defects of high price, high hygroscopicity and the like. Particularly nylon, results in a gradual decrease in the release force of the tie as the ambient humidity increases under different operating conditions. The polypropylene has no hygroscopicity, and the relative humidity of the working condition has little influence on the mechanical properties of the product. Therefore, the application of polypropylene in the tie field is developed, which is beneficial to further expanding the tie application field.
However, due to the uniqueness of the self structure of polypropylene, the polypropylene has the defects of poor low-temperature toughness and low notch impact strength, is not resistant to ultraviolet irradiation, and is easy to generate static accumulation; meanwhile, in the manufacturing process of the thin-wall high-length-diameter-ratio ribbon, in order to improve the fluidity of polypropylene and shorten the forming period, a nucleating agent is usually required to be added in the formula design to improve the crystallization rate of polypropylene and reduce the crystal size, and the addition of the nucleating agent also brings the problems of poorer low-temperature toughness and lower notch impact strength of polypropylene while improving the crystallization behavior of polypropylene; in addition, because the polypropylene composition is prepared first and then the polypropylene composition is injection molded into the ribbon, i.e. the polypropylene is subjected to multiple hot working, there is a potential risk of reducing the physical and mechanical properties of the thin-wall high-aspect-ratio polypropylene ribbon, and the application of the polypropylene ribbon is limited.
Disclosure of Invention
The invention aims to solve the technical problems in the prior art and provide a novel functional master batch suitable for preparing the polypropylene ribbon, which can be directly mixed with a polypropylene resin matrix for injection molding to prepare the thin-wall high-length-diameter-ratio polypropylene ribbon, so that the multi-time thermal processing of the polypropylene resin matrix is avoided, the auxiliary agent powder can be well dispersed in a system in the injection molding process, the phase separation is not easy to occur, and the excellent low temperature resistance and mechanical (mechanical) performance of the system can be provided.

wherein the first functional auxiliary agent is different from the second functional auxiliary agent, and comprises the following components in percentage by mass: 0.2 to 5 percent of lubricant, 0.01 to 2 percent of antioxidant and 0.01 to 2 percent of nucleating agent;
the second functional auxiliary agent comprises one or a combination of more selected from ultraviolet light absorber, antistatic agent and copper inhibitor;
the functional master batch is prepared by mixing the components through an internal mixer, extruding and granulating; wherein, in the preparation process, the temperature of mixing and extrusion granulation is controlled to enable the solid ethylene-octene copolymer to be partially melted, and the ethylene-octene copolymer coats other components in the prepared functional master batch.
In the invention, the temperature of mixing and extrusion granulation is controlled to enable the solid ethylene-octene copolymer to be in a melting-like and non-melting state, so that the ethylene-octene copolymer is prevented from being completely melted; under the action of the rotor, the matrix resin ethylene-octene copolymer gradually coats and disperses the processing aid in the matrix resin through continuous stretching deformation and shearing action.

According to some preferred aspects of the invention, the melting point of the ethylene-octene copolymer is denoted as T, and during the preparation process, the temperature of the mixing and the extrusion pelletization is controlled to be less than t+10 ℃ respectively (in the art, energy input and time input are generally required for melting the resin, and under conditions of reasonable control of the energy input and time input, the melting rate of the resin can be controlled, and therefore, the usual processing temperature will be higher than the melting point of the resin, usually 10-30 ℃ higher, and a certain time window is given).
Further, in the preparation process, the temperature of mixing and the temperature of extrusion granulation are controlled to be T+/-5 ℃.
At the temperature, the matrix resin is partially melted, under the banburying condition, the partially melted resin is effectively mixed with the low-melting-point functional auxiliary agent, the high-melting-point functional auxiliary agent still exists in a solid state, and is dispersed into the mixture of the matrix resin (ethylene-octene copolymer) and the low-melting-point processing auxiliary agent in a solid filling mode, so that the melting phenomenon of most of the processing auxiliary agents is avoided, and further, the occurrence of phase separation caused by compatibility is avoided, the effective distribution of various functional auxiliary agents is realized, and the smooth preparation of master batches is ensured.
