Description
Technical field
The invention belongs to chemical adhesive preparing technical field, specially a kind of environment-friendly high-efficiency Automatic-inflating tyre repair liquid and its
Preparation method.
Background technology
At present, as rapid economic development, the car ownership in China have broken through 100,000,000.
Automobile greatly facilitates the life of people.But work as automotive tire burst, surrounding does not have car repair shop again
When, it is the pretty troublesome and laborious thing of part to change tire.There are many Automatic-inflating tyre repair liquids on the market at present, but generally existing
Organic solvent, some contain the Freon gas forbidden already, and some have very strong corrosivity to wheel hub, in many tyre repairing fluids
Adhesive ingredients adhesion strength is low, and tyre surface adhesion is weaker, and after tire patching, universal durability is not all right, and a few houres that have more than is needed just go out
The phenomenon now slowly leaked.In a word, at present on the market many tire patching nights are universal not environmentally, corrode wheel hub, adhesion is weak, durable
The shortcomings that property difference.
The content of the invention
The present invention is exactly to be directed to above technical problem, there is provided a kind of environmental protection, the efficient, environmental protection that adhesion is strong, persistence is good
Efficient Automatic-inflating tyre repair liquid.
Another object of the present invention is to provide a kind of preparation 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, include the raw material of following weight/mass percentage compositions：
Gross mass percentage composition sum is 100%.
Preferably, environment-friendly high-efficiency Automatic-inflating tyre repair liquid includes the raw material of following weight/mass percentage compositions：
Solid wt in the 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：
Each raw material of the above is weighed in above ratio, then raw material stirs tinning gland, is filled with nitrogen and is prepared into
Environment-friendly high-efficiency Automatic-inflating tyre repair liquid.
Described modified aqueous polyurethane-epoxy resin latex, it is the water-based breast by polyurethane and epoxy acrylic preparation
Liquid.There is splendid adhesion and hot-air aging resistance after the emulsion film forming.Its excellent adhesion combination sawdust and rubber powder
The filling effect of last particle, it can make to be filled at tyre damage uniform, closely knit, it is ensured that tire half a year is air tight.Described changes
Property aqueous polyurethane-epoxy resin latex preparation method is divided into two steps：10g propylene will be added in 20g epoxy resin E-44s first
Acid, tertiary ammonia catalyst n-N dimethyl aniline 0.5g is added, stirring reaction 2h, gets only epoxy acrylic resin at 110 DEG C；
Then 20gTDI, 10g PTMEG PPG400 are added in epoxy acrylic resin, 3h is reacted at 80 DEG C, adds hydrophilic expansion
Chain agent DMPA1-2g, after reacting 1h, 60g water is added, high-speed stirred emulsification, that is, modified aqueous polyurethane-epoxy resin is made
Emulsion.The raw material pointed out in the application is commercially available prod, and rubber powder and sawdust powder generally selected the powder of 20 mesh sieves.
The positive effect of the present invention is embodied in：
(1), green, raw material is all water-based material, without organic solvent.
(2), raw material is free of ammonia, and without aggressive solvent, emulsion does not corrode wheel hub in neutrality.
(3), burn and do not explode using nitrogen, secure and non-combustible, without freon, do not pollute air.
(4), greatly extended as film forming matter using modified aqueous polyurethane-epoxy resin latex of high-adhesion
The usage time of tire.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiment pair
