Abstract
The invention discloses a preparation method of a high-strength rubber composite and relates to the technical field of rubber production. Tapioca and natural latex are mixed and co-precipitated to prepare tapioca/natural rubber composite, so that tapioca is successfully applied to the modified process of natural rubber; the prepared natural rubber composite has good mechanical properties, such as relatively high rigidity, tensile strength and tearing strength and stable property; besides, the mixing process and the sulfidation process are reasonable in parameter setting, the preparation process is simple and easy to grasp, industrial production can be realized, and the production efficiency is improved; the product yield is high, the sources of raw materials are extensive, and the cost is low.
Description
Technical field
The present invention relates to technical field of rubber production, be specifically related to a kind of high-strength rubber composite material and preparation method thereof.
Background technology
Starch source is extensive, mainly contains W-Gum, yam starch, tapioca (flour) etc.The application of starch is very wide, is mainly used in the fields such as food, weaving, papermaking, medicine, tackiness agent.Over nearest 30 years, prepare degradability plastics by starch and plastic blend, expand the application of starch in macromolecular material.Degradability due to starch improves the degradation property of macromolecular material, for single use plastics such as shopping bag, refuse bag, mulch film, tablewares.2002, Goodyear Tire & Rubber Co. of the U.S. succeeded in developing a formula technique, improves the performance of tire with W-Gum, tapioca (flour) is one of main farm produce of China torrid areas, aboundresources, low price, therefore can consider to apply in the modified technique of natural rubber.
Summary of the invention
It is good that problem to be solved by this invention is to provide a kind of mechanical property, the high-strength rubber composite material and preparation method thereof that thermal conductivity is high.
To achieve these goals, the technical scheme that the present invention takes for: a kind of high-strength rubber composite material and preparation method thereof provided, comprises the steps:
(1) under churned mechanically effect, a certain amount of tapioca (flour) breast is added in natural emulsion and mixes 5-10min, then add acetic acid and make it solidify, then grumeleuse compressing tablet is dewatered;
(2) grumeleuse in step (1) after compressing tablet dehydration is put into the loft drier inner drying 45-55min of 75-85 DEG C, obtain tapioca (flour)/natural rubber compound;
(3) mixture obtained in step (2) is placed on mill is carried out mixing, and add Synergist S-421 95;
(4) put on 25t vulcanizing press by the mixture after mixing in step (3) and carry out sulfuration, control curing temperature is 145-155 DEG C, can obtain composite sample.
Preferably, in described step (3), Synergist S-421 95 used is white carbon black and clorafin.
Preferably, controlling muller stirring velocity in the calendering process in described step (3) is 445-460r/min, and control churning time is 25-35min.
Adopt technical scheme of the present invention, by by tapioca (flour) with natural rubber latex is blended coprecipitatedly prepares tapioca (flour)/native rubber composite material, tapioca (flour) is made to be successfully applied in the modified technique of natural rubber, the native rubber composite material mechanical property prepared is good, as hardness, tensile strength and tear strength are all higher, stable performance, and the parameters of described calendering process and sulfuration process arranges rationally, preparation process is simple, easy grasp, suitability for industrialized production can be realized, improve production efficiency, and the output capacity of product is high, raw material sources are extensive, with low cost.
Embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
embodiment 1:
(1) under churned mechanically effect, a certain amount of tapioca (flour) breast is added in natural emulsion and mixes 8min, then add acetic acid and make it solidify, then grumeleuse compressing tablet is dewatered;
(2) grumeleuse in step (1) after compressing tablet dehydration is put into the loft drier inner drying 48min of 75-85 DEG C, obtain tapioca (flour)/natural rubber compound;
(3) be placed on by the mixture obtained in step (2) and mill carried out mixing, and add white carbon black and clorafin as Synergist S-421 95, controlling muller stirring velocity in described calendering process is 450r/min, and control churning time is 30min;
(4) put on 25t vulcanizing press by the mixture after mixing in step (3) and carry out sulfuration, controlling curing temperature is 150 DEG C, can obtain composite sample.
Based on above-mentioned, by by tapioca (flour) with natural rubber latex is blended coprecipitatedly prepares tapioca (flour)/native rubber composite material, tapioca (flour) is made to be successfully applied in the modified technique of natural rubber, the native rubber composite material mechanical property prepared is good, as hardness, tensile strength and tear strength are all higher, stable performance, and the parameters of described calendering process and sulfuration process arranges rationally, preparation process is simple, easily grasps, can realize suitability for industrialized production, improve production efficiency, and the output capacity of product is high, raw material sources are extensive, with low cost.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
