Description
Technical field
The present invention relates to field of rubber technology, particularly relate to the elastomeric material of a kind of high tenacity not easy fracture.
Background technology
Elastomeric material is a kind of macromolecular material that can recover rapidly deformation under gross distortion, and it is one of important foundation industry of national economy, daily, medically provides light industry rubber product for indispensable in people's daily life; For the heavy industry such as digging, traffic, building, machinery, electronics and new industry provide various rubber production unit or rubber components, apply very extensive.In recent years, developing rapidly of rubber industry, has higher requirement to rubber item, elastomeric material must towards functionalization, become more meticulous and the future development of diversification.Traditional single elastomeric material can not meet the service requirements developed rapidly completely.Rubber belongs to elastomerics and lacks crystallizing power, and Intermolecular Forces is little, and free volume is large, so its intensity, hardness, the performance such as wear-resisting and tired are not high, so to rubber through reinforcement, will improve its performance.The strengthening agent that rubber industry is the most traditional is carbon black and white carbon black always, although have certain strengthening action, but these two kinds of strengthening agents all have very low volume density, when adding in rubber, very easily producing and flying upward, processing pollution weight, long processing time simultaneously, mixing energy consumption is large, and black-reinforced goods are single black, and these two kinds of strengthening agents are difficult to give goods higher hardness, better resistance to ventilation property etc.
Graphite is a kind of stratified material, there is excellent lubricity, under stripping state, have very high shape factor, graphite is one of material that specific tenacity is the highest, and has unique functional performance, as electroconductibility and thermal conductivity etc., and cost is low, the strongthener as rubber can improve its tribological property, but the Van der Waals force owing to having between the inert nature of graphite material itself and synusia thereof, directly join in rubber and can greatly reduce its mechanical property, reduce work-ing life.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides the elastomeric material of a kind of high tenacity not easy fracture.
The present invention is achieved by the following technical solutions:
An elastomeric material for high tenacity not easy fracture, is made up of the raw material of following weight part: the strong powder 10-14 of magnesium, accelerant CZ 1-2, melamine phosphate 2-3, polyhutadiene 10-13, polyacrylonitrile 24-27, graphite 12-13, fly ash micro-sphere 3-4, sodium lauryl sulphate 0.7-1, liquid acrylonitrile butadiene rubber 42-55, methacrylic acid 0.6-1, paracril 52-60, styrene-butadiene rubber(SBR) 20-25, china clay 8-10, citric acid 0.2-0.3, cardamom oil 1-2, barium metaborate 6-8, gelatin 6-7, tetrafluoroethylene 4-5, Sodium.alpha.-hydroxypropionate 0.2-0.3.
The elastomeric material of described a kind of high tenacity not easy fracture, be made up of following concrete steps:
(1) mixing of gelatin, the strong powder of magnesium, china clay and barium metaborate is added deionization according to solid-to-liquid ratio 1:2-3-3 and mixes well, then add Sodium.alpha.-hydroxypropionate be heated to boiling under constantly stirring, after dope to be formed, after drying, grinding is for subsequent use;
(2) polyacrylonitrile is added in dimethyl sulphoxide solution, carry out stirring to pulp, concentration controls at 16-18%, add methacrylic acid mixing and stirring again, the drying in vacuum drying oven by graphite and fly ash micro-sphere, adds deionized water according to solid-to-liquid ratio 1:5-7, add sodium lauryl sulphate continuation ultrasonic agitation more even, getting its supernatant liquor is added in polyacrylonitrile solution, stirred at ambient temperature 2-3h, and after filtration, standing and defoaming, spinning, carbonization obtain polyacrylonitrile composite fiber;
(3) by after short for obtained for step (3) conjugated fibre cutting and step (1) product, the liquid acrylonitrile butadiene rubber prepared mix, the calcium chloride water adding 1wt% again flocculates, through washing and in air dry oven under 50-70 ° of C dry 24-30h, cooling after for subsequent use;
(4) paracril, polyhutadiene and styrene-butadiene rubber(SBR) are added in Banbury mixer, be warming up to 90-100 ° of C, with the speed banburying 3-5min of 100-200r/min, add product, accelerant CZ and melamine phosphate prepared by step (3), be warming up to 120-140 ° of C, with the speed banburying 10-15min of 400-600r/min, then add all the other surplus materialss with the speed banburying 5-7min of 200-400r/min, thin-pass 4-6 time, obtains elastomeric material.
Advantage of the present invention is: it is high that the present invention's employing has specific tenacity, heat conduction, conduction and the good graphite of Wear vesistance, as strongthener, can reduce mechanical property greatly because being directly added in rubber, reduction work-ing life, and graphite is added in the spinning solution of polyacrylonitrile by the present invention, passes through spinning, oxidation, the mode of charing obtains the polyacrylonitrile carbon fiber of mineral carbon load, is attached to that it is surperficial by liquid acrylonitrile butadiene rubber, prevents excessive gathering, then blendedly coprecipitatedly obtains rubber master batch, then has excellent intensity with the mixing elastomeric material obtained of rubber, fatigue resistance, heat conduction, anti-attrition, the characteristic such as corrosion-resistant, the strong powder of treated magnesium of interpolation, china clay and barium metaborate substantially improve the fire-retardant of elastomeric material, anti-powdering, high sticky, the performance such as wear-resisting and water-fast, the elastomeric material prepared by the present invention has excellent flame retardant properties, nonflammable, and rubber tensile intensity is high simultaneously, good toughness, not easy fracture, and physical and mechanical properties is excellent, long service life in severe environment.
