Rubber formula design principles can be summarized as follows:1, to ensure vulcanized rubber with the specified technical performance, product quality;2, in the rubber product manufacturing process and processing performance is good, so that products meet high;3, low cost, cheap;4, the use of raw rubber, polymers and various raw materials readily available;5, high labor productivity in the manufacturing process consumes less power;6, in line with environmental protection and health requirements;Any rubber compound is unlikely to achieve all with excellent performance. In many cases, the formulation should follow the following design principles:① In the case without compromising quality, reduce the cost of plastic material;② cost without increasing the case of rubber, to improve product quality. For the performance of rubber products, processing costs and feasibility of three to obtain the best overall balance. With the least material consumption, the shortest time, minimum effort, through the formulation of scientific method, control of raw materials with the inherent laws of practical design formula.PRM IndustryAbstract...Articles section Rubber representation formulaName of the basic formula of raw materials/ Phr PHR formula wt /% volume fraction formula /% production formula/ KGNRSulfurAccelerator MZinc oxideStearic acidCarbon black 100315250 62.201.860.603.101.2431.00 76.701.030.500.631.5419.60 501.50.52.51.025.0Total 161 100.00 100.00 80.5Natural rubber (NR)-based formulationName of standard raw materials NBCSample Number of quality raw materials were the name of the standard NBCThe quality of the sample numbers wereNRZinc oxideStearic acid -370372 10052 antioxidant PBNAccelerator DMSulfur 377373371112.5Note: The curing time is 140 ℃ × 10min, 20min, 40min, 80min.
