Problems solved by technology

[0002] At present, domestic agricultural machinery tires need to be pierced under the piercing machine after the semi-finished products are formed, so as to avoid the air in the semi-finished embryos from being exhausted, resulting in empty shoulders and shoulder cracks, especially nylon agricultural machinery tires. Embryos must be garishly exhausted
Semi-finished embryos are eye-catching, which increases the process in the tire building process, which increases the cost of manpower and equipment operation, resulting in an overall increase in tire costs
If the puncture of the semi-finished embryo is not well controlled, the puncture is too sparse or too dense, which will affect the quality of the finished tire
[0003] In the existing tire building process, gasoline is usually brushed between the tread and the carcass, and between the carcass and carcass to ensure the adhesion between the various parts. The quality of semi-finished products and finished products; due to the reasons of equipment, materials, environment and operators, there will always be gas between the layers, which will cause shoulder voids and shoulder cracks in the finished agricultural tires during the later use of customers

Abstract

The invention discloses a puncture-free tire rough manufacturing process. According to the puncture-free tire rough manufacturing process, on a tire shaping machine, semi-finished rubber including cord fabrics, a tire tip, a tire tread and a tire sidewall are glued to shape layer by layer to manufacture a tire rough. In the shaping and gluing process of the semi-finished rubber, tackifying mucilage glue is equally daubed between every two adjacent semi-finished rubber layers, and then the semi-finished rubber layers are compacted after being glued together. The tackifying mucilage glue comprises 100 parts of natural rubber (NR), 35-50 parts of tackify resins BHK1360, 3000-4000 parts of gasoline, 1.5 parts of sulphur and 1.0 part of accelerant. The puncture-free tire rough manufacturing process has the advantages that by detecting performance of 15.4-24R1 agricultural machinery tires, all performance of tire tread rubber can reach national standards, by tracking and verifying appearance and quality of a finished tire, no appearance quality defect like tip scars, bubbles and the like is detected, and the finished tire is high in quality in use after being verified in markets.
