[0002] Prior art table tennis mostly adopts celluloid to be manufactured as raw material, and although the table tennis ball that celluloid is made has good performance, celluloid shortcoming is also obvious: the one, celluloid is to be main raw material with dehydrated nitrocellulose, It is flammable and explosive, so there are great safety hazards in the raw material stage, production stage, and storage and transportation process after making table tennis products
Second, for safety, nitrocellulose needs to be added with water during transportation, and needs to be dehydrated during use. There is a large amount of waste liquid discharge, which will bring harm to the environment and is not environmentally friendly. Third, the manufacturing process of celluloid to prepare table tennis balls is complicated. , long production cycle
There are also other new materials that replace celluloid in the market, but these new materials generally do not meet the performance level of celluloid, and the manufacturing cost remains high. Materials that are small in size and whose performance is equal to or surpasses that of celluloid are the difficulties that all personnel in the field of table tennis manufacturing need to overcome.

preparation example Construction

[0025] As a preferred embodiment, the components and parts by mass of the compatibilizer are further optimized as follows: 91-97 parts of the second AS resin, 2-6 parts of comonomer, glycidyl methacrylate (MA) 1 -3 parts, initiator 0.1-0.3 parts, second stabilizer 0.1-0.4. Its preparation method comprises the following steps:

[0026] (1) Weigh each component according to the proportion, place it in a high mixer and stir for 5-10 minutes to obtain mixture A;

[0027] (2) Put the mixture A in a twin-screw machine, melt and extrude, and granulate. The zone temperature is 180-200°C, the fifth zone temperature is 180-200°C, the head temperature is 210-230°C, the barrel residence time is 1-3 minutes, and the melt pressure is 10-20MPa.

[0028] The glycidyl methacrylate is a strong polar reactive group, and is a polymer interface coupling agent, a compatibilizer, and a dispersion accelerator, so that the material has high polarity and reactivity, and can also improve compatibilit...

Embodiment 1-4

[0035] Prepare the compatibilizer maleic anhydride grafted polyketone according to the components and parts by mass in Table 1. The preparation method is: (1) weigh each component according to the proportion, place it in a high mixer and stir for 8 minutes to obtain the mixture;

[0036](2) Place the mixture obtained in step (1) in a twin-screw machine, melt and extrude, and granulate. 180-200°C, the temperature of the fourth zone is 160-180°C, the temperature of the fifth zone is 160-180°C, the temperature of the die head is 190-210°C, the residence time of the barrel is 1-3 minutes, and the melt pressure is 10-20MPa.

[0039]

[0040] Glycidyl methacrylate MA grafted AS compatibilizer was obtained through the above steps, and the grafting rate of Example 4 was the highest. The results showed that the grafting rate of glycidyl m...

Embodiment 9-12

[0042] Adopt the component formula shown in table 2 (all are mass ratio) to be used for preparing table tennis composite material, wherein the compatibilizer of embodiment 5-8 and comparative example 2-4 adopts the phase that above-mentioned embodiment 3 obtains Toner. The preparation method is as follows: weigh each component according to the proportion; mix the compatibilizer, lubricant and stabilizer evenly, mix the other components evenly, and add them to the twin-screw extruder in different areas at the same time to extrude, after water cooling, pelletizing , to produce a nylon / polyketone alloy material with excellent performance. Among them, the temperature of the twin-screw extruder from the feed section to the machine head is as follows: the temperature of the first zone is 160°C-180°C, the temperature of the second zone is 200°C-230°C, the temperature of the third zone is 200°C-230°C, and the temperature of the fourth zone is 200°C. ℃-230℃, the temperature of the fif...

Abstract

The invention discloses a composite material for preparing a table tennis ball and a preparation method of the composite material. The composite material comprises the following components in parts bymass: 10-30 parts of first AS (acrylonitrile-styrene) resin, 30-70 parts of cellulose acetate, 10-30 parts of ABS (acrylonitrile-butadiene-styrene) powder, 10-30 parts of a toughening agent and 3-6 parts of a compatibilizer, 0.5-3 parts of a first stabilizer, 0.5-1 parts of a lubricant, 0.2-1 parts of an antioxidant, 0.5-2 parts of a weathering agent and 1-5 parts of an auxiliary agent. Comparedwith a celluloid material, the composite material prepared with the method can be prepared into table tennis balls directly through injection molding, and has the advantages of safe production, biodegradability and less environmental pollution. Meanwhile, all performance indexes of the prepared table tennis balls are excellent and the partial performance exceeds that of celluloid.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a new plastic table tennis material and a preparation method thereof, which can replace celluloid and be used in table tennis production. Background technique [0002] Prior art table tennis mostly adopts celluloid to be manufactured as raw material, and although the table tennis ball that celluloid is made has good performance, celluloid shortcoming is also obvious: the one, celluloid is to be main raw material with dehydrated nitrocellulose, It is inflammable and explosive, so there is a greater safety hazard in the raw material stage, production stage, and storage and transportation process after the table tennis product is made.
