Abstract

A compression resistant and long-lasting scented dog toy and its preparation method. The compression resistant and long-lasting scented dog toy comprises a rubber body and cloth fluidized on it. The rubber body is made of following raw materials by weight: natural rubber, zinc oxide, camphene, stearic acid, anti-aging agent, edible gum, starch, microcrystalline wax, white carbon black, naphthenic oil, silicone rubber, butyl rubber, accelerant, antiozonant, medical light calcium carbonate, edible rapeseed oil, flavor enhancer, sour agent, talcum powder and fatty acid softening agent. The invention is made of a rubber body and cloth fluidized on it. Flavoring agents are mixed in the rubber body so as to produce a compression resistant and long-lasting scented body with durable fragrance.

Claims

5. The compression resistant and long-lasting scented dog toy according to claim 1, wherein the sour agent is citric acid or malic acid.

6. A method of making a compression resistant and long-lasting scented dog toy according to claim 1, comprising the following steps:

(1) measure each raw material by specified weight;

(2) add the zinc oxide, the microcrystalline wax, the white carbon black, the naphthenic oil, the medical light calcium carbonate and the edible rapeseed oil into a mixer and then mix them 20-30 min at a speed of 45-65 rpm to obtain the prepared auxiliary material;

(3) put the natural rubber, the silicone rubber and the butyl rubber into an internal mixer for uniform mixing at a mixing temperature of 60-80°

C. and a speed of internal mixer of 40-50 rpm, once the material temperature increases to 85-95°

C., add the prepared auxiliary material, the camphene, the stearic acid, the edible gum, the talcum powder and the fatty acid softening agent for mixing 6-10 min, after that, add the starch for uniform mixing and then discharge the rubber at a temperature of 120-130°

C.;

(4) add the anti-aging agent, the accelerant, the antiozonant, the flavor enhancer and the sour agent for mixing 4-8 min at a reaction temperature of 140-145°

C., once the rubber is arranged to specified shape, use the existing fluidization process to produce the rubber body; and

(5) stitch the fluidized cloth onto the semi-finished rubber body, which is then filled with PP fiber to complete the toy.
