Abstract
The invention belongs to the technical field of preparation of chemical adhesives, and in particular relates to an environment-friendly efficient automatic-inflation tire repair fluid and a preparation method thereof. The environment-friendly efficient automatic-inflation tire repair fluid comprises the following raw materials in percentage by mass: 30-40% of modified waterborne polyurethane-epoxy resin emulsion, 8-10% of rubber powder, 1-2% of sawdust powder, 1-3% of ethylene glycol, 2-5% of polyvinyl alcohol, 0.5-1% of OP-10, 0.5-1% of lauryl sodium sulfate, 8-10% of water, and 28-49% of compressed nitrogen gas, based on 100% in total. The automatic-inflation tire repair fluid is green and environmentally-friendly, takes water-based materials as raw materials, and does not contain an organic solvent; moreover, the raw materials do not contain ammonia gas and do not contain a corrosive solvent, so that the emulsion is neutral, and hubs are not corroded; nitrogen gas which is safe, does not burn and does not explode is adopted, and the atmosphere is not polluted due to the fact that Freon is not contained; and the high-cohesiveness modified waterborne polyurethane-epoxy resin emulsion is used as a film-forming substance, so that the use time of the tire is greatly prolonged.
Description
Technical field
The invention belongs to chemical adhesive preparing technical field, be specially a kind of environment-friendly high-efficiency Automatic-inflating tyre repair liquid and
Preparation method.
Background technology
At present, along with rapid economic development, the automobile pollution of China has broken through 100,000,000.
Automobile greatly facilitates the life of people.But, work as automotive tire burst, around there is no again car repair shop
Time, changing tire is the pretty troublesome and laborious thing of part.There are many Automatic-inflating tyre repair liquids at present, but generally existed
Organic solvent, some contains the Freon gas forbidden already, and some has the strongest corrosivity to wheel hub, in a lot of tyre repairing fluids
Adhesive ingredients adhesion strength is low, and tyre surface adhesion is more weak, and after tire patching, universal durability is not all right, within have more than is needed several hours, just goes out
The phenomenon the most slowly leaked.In a word, a lot of tire patchings the most on the market are universal not environmentally for night, corrode wheel hub, and adhesion is weak, durable
Property difference shortcoming.
Summary of the invention
The present invention is just for above technical problem, it is provided that a kind of environmental protection, the environmental protection that efficient, adhesion is strong, persistency is good
Efficiently Automatic-inflating tyre repair liquid.
Another object of the present invention is to provide the preparation of a kind of environment-friendly high-efficiency Automatic-inflating tyre repair liquid of above-mentioned record
Method.
The concrete technical scheme of the present invention is as follows:
A kind of environment-friendly high-efficiency Automatic-inflating tyre repair liquid, including the raw material of following weight/mass percentage composition:
Gross mass percentage composition sum is 100%.
As preferably, environment-friendly high-efficiency Automatic-inflating tyre repair liquid includes the raw material of following weight/mass percentage composition:
Solid wt in described modified aqueous polyurethane-epoxy resin latex is 35%.
The preparation method of environment-friendly high-efficiency Automatic-inflating tyre repair liquid comprises the following steps:
Weigh above each raw material in above ratio, then by uniform for raw material stirring tinning gland, be filled with nitrogen and be i.e. prepared into
Environment-friendly high-efficiency Automatic-inflating tyre repair liquid.
Described modified aqueous polyurethane-epoxy resin latex, is the aqueous breast prepared by polyurethane and epoxy acrylic
Liquid.There is after this emulsion film forming splendid adhesion and hot-air aging resistance.The adhesion of its excellence combines sawdust and rubber powder
The filling effect of end particle, can make to be filled at tyre damage uniform, closely knit, it is ensured that tire is air tight for half a year.Described changes
Property aqueous polyurethane-epoxy resin latex preparation method be divided into two steps: first 20g epoxy resin E-44 will add 10g propylene
Acid, adds tertiary ammonia catalyst n-N dimethyl aniline 0.5g, and at 110 DEG C, stirring reaction 2h, gets only epoxy acrylic resin；
Then in epoxy acrylic resin, add 20gTDI, 10g PTMEG PPG400, react 3h at 80 DEG C, add hydrophilic expansion
Chain agent DMPA1-2g, after reaction 1h, adds 60g water, high-speed stirred emulsifying, i.e. prepares modified aqueous polyurethane-epoxy resin
Emulsion.The raw material pointed out in the application is commercially available prod, rubber powder and sawdust powder and was generally selected the powder of 20 mesh sieves.
The positive effect of the present invention is embodied in:
(1), environmental protection, raw material is all water-based material, without organic solvent.
(2), raw material without ammonia, without aggressive solvent, emulsion is neutrality, does not corrode wheel hub.
(3), using nitrogen, secure and non-combustible burns and does not explodes, without freon, and not atmosphere pollution.
(4), use the modified aqueous polyurethane-epoxy resin latex of high-adhesion as film forming matter, extend greatly
Use time of tire.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with detailed description of the invention pair
