Problems solved by technology

[0002] The main material of the pet ball produced by traditional technology is made of rubber material alone, which has the defects of poor toughness, low strength, and weak air holes on the surface. After repeated biting, the surface of the ball is easily damaged.
On the other hand, N, N-dinitrosopentamethylenetetramine (foaming agent H) is used in the traditional pet ball production process. After high-temperature vulcanization, the residue of this foaming agent contains nitro Or nitroso derivatives, which are toxic and harmful to pets

Embodiment Construction

[0027] 1. Preparation of OBSH modified foaming agent:

[0028] 1. Weighing:

[0029] Weigh 5 kg of 4,4-oxobisbenzenesulfonylhydrazide, 1 kg of zinc stearate and 1.5 kg of urea with a particle size of 1000-2000 mesh, respectively.

[0030] 2. Preparation process:

[0031] Put all the above materials into a high-speed mixer, and the speed is not lower than 5000 rpm.

[0032] After 2 to 5 minutes, stop the machine and let it stand for 30 minutes until the material settles.

[0033] Open the cover after 0.5 hours, visually inspect the surface of the powder to be uniform without impurities, and discharge after uniform color, ready to use.

[0034] 3. The product characteristics and parameters of the obtained OBSH modified foaming agent:

[0035] (1) White particles with uniform color.

[0036] (2) The critical temperature of foaming is 150°C.

[0037] 2. Manufacture of pet balls:

[0038] 1. Manufacturing steps:

[0039] (1) Weigh each raw material according to each recipe....

Abstract

The invention discloses a micro-foamed pet ball and a manufacturing method thereof, and relates to the technical field of composite material production. The manufacturing method comprises the following steps: mixing NR, POE, carbon black, an anti-aging agent and a plasticizer, mixing through an internal mixer, discharging to obtain a mixed material; putting the mixed material on an open mill for cooling, dispersing and mixing, adding an OBSH modified foaming agent, a vulcanizing agent and an accelerant, uniformly mixing, thinning, sheeting, and cooling to obtain a mixed material; preparing a smooth blank from the mixed material on an extruder through a high shearing force, cutting the blank into a coarse blank, coating the coarse blank by talcum powder, putting the coarse blank into a forming mold, vulcanizing in a high-temperature vulcanizing agent, demolding, cooling, and trimming to obtain the product. The product is light in hand feeling, good in rebound resilience, bright in color, good in toughness and tearing property and smooth in surface, can attract pets to play, and is high in pet biting durability.

Description

technical field [0001] The invention relates to the technical field of composite material production. Background technique [0002] The main material of pet balls produced by traditional technology is only made of rubber material, which has the defects of poor toughness, low strength, and weak air holes on the surface. After repeated biting, the surface of the ball is easily damaged. On the other hand, N, N-dinitrosopentamethylenetetramine (foaming agent H) is used in the traditional pet ball production process. After high-temperature vulcanization, the residue of this foaming agent contains nitro Or nitroso derivatives, which are toxic and harmful to pets. Contents of the invention [0003] In order to overcome the above defects in the prior art, the object of the present invention is to provide a microfoamed pet ball. [0004] The invention is mainly composed of NR, POE, carbon black, anti-aging agent, plasticizer, OBSH modified foaming agent, vulcanizing agent and acc...
