Problems solved by technology

However, in this method, the nucleating agent and the fiber are only simply mixed, and have not been substantially integrated. Therefore, in actual use, it is inevitable that the two components will be separated from each other, and the real effect will not be achieved.
[0005] So far, no special additives for polybutene-1 have been released

Embodiment 1

[0029] The hydroxy aryl phosphate powder 5g solid aluminum was placed 250mL N, N- dimethyl formamide and heated to 130. deg.] C, stirred for 1h dissolved completely. Then, the particle diameter of 20μm 1g bacterial cellulose powder was added to the above mixture, the mixture was slowly added dropwise 20mL succinic anhydride. After the dropwise addition, reaction was stirred for 6 hours. The mixture was suction-filtered after the completion of the reaction substance, a large amount of hot methanol and then repeatedly washed 10 times, and the resulting white powder was dried at 80 ℃. The above-described special additives and 1g 1000g polybutene-mixed in a high speed mixer, after extrusion, pelletizing, injection molding and other molding step. At 24 hour intervals, the tensile and impact properties of the material according to the method of 9341-2008 GB / T 1040-2006 and GB / T. See specific data figure 1 , figure 2 Indicated.

Abstract

The invention relates to a method for preparing a special auxiliary agent for improving the mechanical properties of polybutene-1 at the initial stage of molding and the application of the special auxiliary agent, which belongs to the technical field of polymer materials, and specifically comprises the preparation of aryl phosphate hydroxyaluminum salt solid powder Put it in an organic solvent according to a certain proportion, stir and dissolve at 100°C-130°C until it is completely dissolved, and obtain mixture A; add bacterial cellulose powder to mixture A to obtain mixture B; Acid anhydride, stirred for 4-10 hours; after the reaction, the reacted substance was suction-filtered, then washed repeatedly with methanol at 50-60°C, and the obtained white powder was dried to obtain polybutene-1 Special auxiliary agent, the special auxiliary agent prepared by the present invention is mixed with polybutene-1, which can make the mechanical properties of polybutene-1 reach the mechanical properties of crystal form I at the initial stage of molding, meet the use requirements, and then reduce production costs.

Description

Technical field [0001] The present invention relates to the use of special additives for improving the mechanical properties of polybutene-shaped initial preparation method -1 and special additives, it belongs to the technical field of polymer materials. Background technique [0002] Polybutene -1 (PB-1) having excellent impact resistance, stress crack resistance, creep resistance, heat-pressure resistance, moisture barrier properties and electrical insulation properties, it is widely used in foreign countries water field of pipes and fittings and, HVAC systems, heating systems, is an excellent green pipe, known as "plastic gold." However, polybutene-1 polymer polymorph, Form II is first generated after melt molding process, having a poor tensile strength, flexural strength is poor, the mechanical properties of unstable characteristics. If subjected to external force such as squeezing or bending at the beginning of the molding will be irreversible damage to the storage and use of...
