AI Technical Summary

Problems solved by technology

However, the raw materials for making teething sticks or dog chews are sheared and pulverized animal hides and sawdust, which are mechanically compressed or glued with starch and gelatin, which are not resistant to tearing and tearing, and the life of dog chews is relatively short.
At the same time, the dog chews or teething sticks prepared by this method are relatively hard, which will cause greater damage to the pet’s gums. It needs to be improved by adding toughening particles, but on the other hand, the bite resistance of the dog chews is reduced.
And the raw materials for preparing dog chews or teething sticks are perishable materials with short shelf life

Abstract

The invention discloses ultra-tear-resistant mixing rubber and a preparation method thereof. The ultra-tear-resistant mixing rubber comprises the following materials in parts by weight: 60-65 parts of constant-viscosity natural rubber, 35-40 parts of rare-earth butadiene rubber, 75-85 parts of white carbon black, 7.5-8.5 parts of silane coupling agent, 1.5-2.5 parts of antioxidant, 15-25 parts of white oil, 1.8-2.5 parts of stearic acid, 3.5-5 parts of zinc oxide, 1.4-1.8 parts of guanidine accelerator, 1.7-2 parts of sulfenamide accelerator and 0.8-1.2 parts of sulfur. The invention develops a formula of the ultra-tear-resistant mixing rubber, and by adoption of the formula, the formula of traditional dog-chewing rubber, adopting livestock skin as main materials, can be replaced, and the problems of short service life, larger hardness and easy deterioration of the traditional molar rods or dog-chewing rubber are solved.

Description

technical field [0001] The invention relates to a mixed rubber and a preparation method thereof, in particular to a super tear-resistant mixed rubber which can be used for preparing dog chews or teething sticks and a preparation method thereof, and belongs to the technical field of pet products. Background technique [0002] Traditional molar sticks and dog chews are made of animal hides as the main raw material. After processing such as depilation and degreasing, sawdust is added, dog food is mechanically pressed and hot-extruded, and then shaped and dried. Some starches are added. Or gelatin bonding, at the same time, pet favorite essence is added to increase pet appetite, so that it is a product for pets to play with. [0003] Conventional dog chews have a short lifespan and are prone to discoloration and odor. The newly-applied "Live Dog Chew" patent (Application No.: CN03131539.9) is an improvement on the basis of the traditional dog chew, adding toughening particles t...
