Abstract
The invention relates to a temperature-resistant polymer sealing material for manufacturing tires, which comprises the following main components and mixture ratio (weight percentage): 38 percent of polythene emulsion, 40 percent of colophony glyceride, 9 percent of expanded nanometer graphite, 2 percent of triguaiacyl phosphite, 5 percent of active silica gel, 1 percent of curing agent, 2 percent of active catalyst and 3 percent of filler. The material is used for the inner sealing material of tubeless air leakage preventing tires. Compared with the sealing elastomer material adopted by the prior art, the main characteristic of the sealing material lies in that the expanded nanometer graphite greatly improves the temperature-resistant stability of the sealing material during the advance of high-speed tires. In addition, component materials are easy to purchase and synthesize and cheaper than international similar products, thereby immensely optimizing the process of anti-leakage anti-prick safety tire inner layer technology.
Description
Technical field
The present invention relates to the Polymer Synthesizing novel material, relate in particular to a kind of high temperature resistant high molecule sealing materials that is used to make tire.
Background technology
Since the sixties in last century, in the time of along with the utilization of meridian tubeless tyre, professional in the world tire scientific research institution studying always a kind of can be on market from cost and the anti-tie safety tread of technical all receptible leakproof.Last century the eighties, major technology is presented as the technical skill in the liquid glue perfusion tire, along with being evenly distributed in the tire, the rotation of tire shows, when having a flat tire, glue contacts with air and solidifies the effect that reaches mending-leakage, but, do not admitted by market because of having a strong impact on the various technical features of tire always.Last century, the nineties was to adopt polyisoprene rubber or silicon rubber to spray the solid glue body of one deck 2-3mm at inner layer of tire in the great technological breakthrough in this field.Adopt the active memory mode of healing wound automatically, anti-tie puncture-proof tire technology stepped to the utilization of real market go a step further, but also have following unfavorable factor:
1) material price costliness such as used polyisoprene rubber; 2) inner tube of a tyre coating is in this tire high-speed cruising, and Yin Wendu is too high and make coating local deformaton have a strong impact on this movement of the foetus balance; 3) activity of inner tube of a tyre coating, ageing resistance all can't obtain substantial technological breakthrough; 4) the raw material dependence on import because of adopting, cost and industrialized development all become the factor of restriction popularization.
Therefore, research and development and make a kind of high temperature resistant, simultaneously possess the constructed performance of elasticity leakproof glue in the world again, with low cost and can finish " heatproof high molecule sealing materials " of buying raw material fully at home, become and really can make anti-tie leakproof safety tire move towards market-oriented bottleneck problem.
Summary of the invention
Purpose of the present invention is at market, goes up the deficiency that exists at technical and technology utilization, and the series of optimum of carrying out is researched and developed, and a kind of heatproof high molecule sealing materials that is used to make tire of superior performance is provided.
The objective of the invention is to be achieved through the following technical solutions.
A kind of heatproof high molecule sealing materials, the proportioning that its composition reaches with weight percent is:
1. polyethylene emulsion 38%
2. rosin glyceride 40%
3. expansion nano graphite 9%
4. GW-540 2%
5. activated silica gel 5%
6. solidifying agent 1%
7. active catalyst 2%
8. weighting agent 3%
Raw material is carried out molten state by the said ratio mixing synthesize, promptly make product heatproof high molecule sealing materials of the present invention.
Polyethylene emulsion is the component part of thermoplasticity colloid, and tackifier are rosin glyceride, and refractory agent is an expansion nano graphite, anti-aging agent is a GW-540, and affinity agent is an activated silica gel, and solidifying agent is 590 solidifying agent, active catalyst is a N-methyl diethyl alkyd, and described weighting agent is a silica powder.
The listed starting material of the present invention all can be finished domestic procurement, simultaneously, adopt proprietary synthetic technology, are developed into ideal heatproof high molecule sealing materials more.Being effective in anti-tie leakproof safety tire moves towards mass-producing market effective technical support is provided.
The present invention has reached above-mentioned technical purpose, and product has following high-performance:
1) high temperature resistant, in be coated with colloid and have good stability;
2) use properties of raw material breaks through original technical feature;
3) Cai Gou raw materials cost is more cheap, and raw material can be finished buying at home.
Embodiment
The body matter of synthesis technique is the manufacturing that the recombining process of employing melting state is finished material.
Embodiment:
1) the two-way glue making machine of interior axle is carried out preheating, temperature is controlled at 160 ℃ ± 5 ℃;
2) take by weighing 380 gram polyethylene emulsions, 400 gram rosin glycerides, 90 gram expansion nano graphite, 20 gram GW-540s, 50 gram activated silica gels, 10 grams, 590 solidifying agent, 20 gram active catalyst N-methyl diethyl alkyd, 30 gram silica powder weighting agents, above-mentioned raw materials is by stirring in the proportioning adding container, synthetic.React and to obtain product heatproof high molecule sealing materials of the present invention in one hour.
The heatproof high molecule sealing materials that the present invention makes, its technical indicator is:
Melt viscosity: average 8000-15000
Softening temperature: average 125 ℃-145 ℃
Low temperature: average-40 ℃-0 ℃
The present invention develop and the material of the identical performance that makes of heatproof high molecule sealing materials and the present external raw material of employing have fairly obvious high temperature resistant advantage.
