The vacuum tire self-repairing cement has the advantages of readily available raw materials, mild reaction conditions, simple preparation process, low cost, environmental protection, instant repairing effect and convenient use, can rotate along with a wheel after being pouring into the tire, can automatically and quickly agglutinate a wound, and can prevent the wound of the tire from air leakage and slow leakage of the tire; the temperature resistance range is between 10 DEG C below zero and 60 DEG C; and the vacuum tire self-repairing cement has long product preservation time which can be 5 to 7 years under the normal-temperature and dry condition, can be applied to repairing old tires, prolongs the service life, and plays a role of maintaining tires.
Description
Technical field
The present invention relates to a kind of chemical binder, relate in particular to a kind of vacuum tire self-repairing cement.
Background technology
Doughnut in use weares and teares, to be pricked, leak gas be inevitable, the tire patching technology that is absolutely necessary.The method that conventional tire is repaired mainly contains three kinds:
Cold-patch is that injured tire is unloaded from wheel rim, finds after the wound, after the foreign matter cleaning with the wound place, sticks special-purpose tire patching rubber from inner layer of tire, thereby finishes mending-leakage; Its advantage is to repair bigger wound, shortcoming is not block the broken hole of carcass, and is durable inadequately, can not block air and moisture content in the driving process afterwards, might cause that thereby the steel wire corrosion causes squeegee action, the mend phenomenon that leaks air once more probably.
Vulcanizing is tire patching measure the most completely, tire will be unloaded from wheel rim during tire patching, and the sheet rubber with special use is attached at wound then.With baking machine wound is toasted again, fit fully until sheet rubber and tire; The benefit of vulcanizing is very durable, can seal broken hole, and protection steel wire carcass does not worry that substantially the wound place can repeat gas leakage; Shortcoming is that the time is oversize, and labour intensity is big, and the technical requirements during construction is higher, and temperature control does not with great difficulty cause squeegee action.
Adhesive tape plug reinforcing method is quick and tire patching method easily, is divided into resin adhesive tape and sulfuration adhesive tape two classes, and simple to operate without detaching tyre, shortcoming is to have grown the time to leak gas slowly.
Also useful at present puncture-mending agent is to tyre repair, and the puncture-mending agent product mainly contains pulvis and aqua; Pulvis mainly contains the starch talcum powder and terra alba is a raw material, and the tire patching weak effect can only be kept several hrs; Aqua is many, still can be existed and leak slowly under powerful tire pressure with Vinyl Acetate Copolymer, polyvinyl alcohol, light calcium carbonate, Mierocrystalline cellulose, rubber grain, rubber powder etc., bad adhesion, and poor stability, easy freezing, thermo-labile, the problem that the storage time is short.
Summary of the invention
Technical problem to be solved by this invention provides a kind of vacuum tire self-repairing cement, has overcome the shortcoming of above-mentioned prior art; Vacuum tire self-repairing cement provided by the invention has the moment repair efficiency, and is easy to use, effectively prevents gas leakage, high temperature resistant and low temperature.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of vacuum tire self-repairing cement, described by weight vacuum tire self-repairing cement is composed of the following components:
Aqueous polyvinyl acetate emulsion 35-48
Polyvinyl formal 18-25
Mierocrystalline cellulose 8-15
Natural emulsion 17-22
Polymerization adhesion promotor 3-5
Carbon black color paste 1-3
Water 70-195
Described Mierocrystalline cellulose is a carboxymethyl cellulose; Do not contain the free formaldehyde resistates in the described polyvinyl formal, be formaldehydeless environmentfriendly products; Described polymerization adhesion promotor is a water-based silicon-dioxide.
Aqueous polyvinyl acetate emulsion has good cementability and water tolerance, alkali resistance and weathering resistance preferably in above-mentioned vacuum glue composition; The polyvinyl formal water-tolerant, extensibility the water-proof binding effect is arranged, and this polyvinyl formal does not contain free formaldehyde resistates, Environmental Safety; Carboxymethyl cellulose is soluble in water; can form full-bodied colloid, solution, adhesion is arranged, thickening, flow, characteristics such as emulsification dispersion, figuration, water conservation, protective colloid, film forming, acidproof, salt tolerant; and physiology is harmless, can improve water-retentivity and intensity and heat-resistant stability and salt tolerance.The polymerization adhesion promotor is a water-based silicon-dioxide, and the sticking power of the glue of can tackifying improves the high-temperature behavior of viscous adhesive, stability, and extend the shelf life.And carbon black color paste can be used as the viscosity modifier and the tinting material of liquid sealant.Natural emulsion has good film forming properties, and wet gel is powerful high, and mechanical property is good, the few mechanical stability height of nonrubber component content, and froth stability is good.
The method for preparing described vacuum tire self-repairing cement comprises by following steps and forms:
(a) be 1 with water according to weight ratio with aqueous polyvinyl acetate emulsion: 1-2: 1 mixes the formation solution A;
(b) be 1 with water according to weight ratio with polyvinyl formal: 1-2: 1 mixes the formation solution B;
(c) be 1 with water according to weight ratio with Mierocrystalline cellulose: 3-1: 5 mix the formation solution C;
(d) be 2 with water according to weight ratio with natural emulsion: 1-3: 1 mixes the formation solution D;
(e) be that 70-90 ℃ water is 1 according to weight ratio with polymerization adhesion promotor and temperature: 5-1: 7 mix, and add carbon black color paste again and form solution E;
(f) solution A, solution B, solution C, solution D and solution E are mixed stirring, low whipping speed 500-1000 rev/min was stirred 1-3 hour down, after static 30 minutes, continued to stir 0.5-1.5 hour, obtained product.
More than each step all under normal pressure, carry out.
More than each component raw material be the commercially available prod.
The present invention has the following advantages:
Vacuum tire self-repairing cement raw material of the present invention is easy to get, the reaction conditions gentleness, and preparation process is simple, and cost is low, does not have generation of waste materials in the production process, is environmental protection production; Described vacuum tire self-repairing cement has the moment repair efficiency, and is easy to use, and cohesive force is strong, glue is injected tire, and along with wheel rotates, this vacuum tire self-repairing cement can bonding voluntarily rapidly wound, effectively prevent leaking slowly of tire wound gas leakage and tire, can seal rapidly the nail hole in 6 millimeters of the diameters; But this glue heatproof degree scope is-10-60 ℃; The product shelf time is long, can preserve 5-7 under the Air drying, also can be used for the repairing of old tire, has prolonged work-ing life, and tire is had maintenance action.
