Abstract
The present invention discloses a liquid UV curing and sealing agent for replacing solid sealing rings of automobile oil tank covers and a preparation method therefor. The sealing agent comprises the components of: alkoxy tetrahydrofuran acrylic acid, N-2-vinyl pyrrolidone, alkoxy dodecyl acrylate, polyester, polyester glycol, high boiling point acrylate, a thixotropic agent, and a photoinitiator. The sealing agent has beneficial effects that: by choosing a UV resin, a reactive diluent, a thixotropic agent, a photoinitiator and performing segmented mixing and stirring according to a proportion, a liquid sealing agent that meets a requirement of automobile oil tank covers is prepared, and the product has a good adhesion on an oil tank cover substrate; the product has a good formability, and can coordinate with automatic glueing devices, and realizes a consistency of every product. The present invention further discloses a preparation method of the above sealing agent, and by a design of light curing process, a rapid flow line production is realized, and an oil resistance and a weathering resistance of the product both meet the sealing requirement of oil tank covers.
Description
Technical field
The present invention relates to sealing agent technical field, particularly relate to liquid UV curing sealant of a kind of alternative vehicle fuel tank cap sealed solid circle and preparation method thereof.
Background technology
The sealing of current vehicle fuel tank cap realizes mainly through sealed solid circle, and the shortcoming of existing sealed solid circle is 1) to the fuel tank cap of different size must mold produce, costly, unified poor for applicability; 2) do not have cementability to material, quality of fit requires high.
Summary of the invention
For solving the problems of the technologies described above, the present invention coordinates fluid sealing techniques to develop a kind of single-component ultraviolet light polymerization sealing agent of enhancing productivity and reducing production cost, the special reliability for vehicle fuel tank cap sealing and erosion resistance aspect show very excellent, and the technical problem of solution comprises:
1) single-liquid type, convenient operation, is applicable to high speed coating technique, ensures the unity of each product size;
2) medium viscosity, high thixotropic energy, meets the gluing requirement of different heights;
3) after sealant cures Hardness Control between shore A15-25;
4) there is good bonding force to different fuel tank cap base material, improve sealing effectiveness;
5) UV-curing technology is adopted, fast curing-formed, enhance productivity;
6) excellent erosion resistance is had to gasoline, diesel oil, machine oil.
For achieving the above object, the technical scheme that the present invention takes is: a kind of liquid UV curing sealant of alternative vehicle fuel tank cap sealed solid circle, is made up of the raw material of following parts by weight:
As the preferred implementation of the liquid UV curing sealant of alternative vehicle fuel tank cap sealed solid circle of the present invention, described thixotropic agent is multi-hydroxy carboxy acid's amides solution.
As the preferred implementation of the liquid UV curing sealant of alternative vehicle fuel tank cap sealed solid circle of the present invention; described light trigger is 2-methyl isophthalic acid-(4-first mercaptophenyl)-2-beautiful jade-1-acetone and 2; the mixture of 4,6-(trimethylbenzoyl) diphenyl phosphine oxide.
In addition, the present invention also provides a kind of method preparing aforesaid liquid UV curing sealant, comprises the following steps:
A) by the parts by weight of above-mentioned raw materials composition, various raw material is taken;
B) by above-mentioned raw materials order from front to back, drop in ultraviolet light polymerization equipment successively, obtain described liquid UV curing sealant.
The liquid UV curing sealant of a kind of alternative vehicle fuel tank cap sealed solid circle of the present invention, segmentation mix and blend is carried out by proportioning by selecting UV resin, reactive thinner, thixotropic agent, light trigger, mix the fluid sealant meeting vehicle fuel tank cap seal request, product has good bonding force to fuel tank cap base material; The good moldability of product, can coordinate automatic pasting equipment, realizes the consistence of each product; By the design of ultraviolet curing process, realize fast pipeline and produce; The oil-proofness of product and weathering resistance all meet the seal request of fuel tank cap.
Embodiment
For better the object, technical solutions and advantages of the present invention being described, below in conjunction with specific embodiment, the invention will be further described.
Three embodiments as shown above, preparation method is as follows:
First accurately take various raw material by formula rate, then put in uv equipment in order, obtained liquid UV curing sealant.
Respectively above-mentioned three embodiments are carried out to the test of related property, such as, hardness, elongation at break, use temperature scope and oil-proofness etc. after viscosity, surface drying time, solidification, can find out, three embodiment products obtained therefroms all possess the excellent characteristic of each side.
Finally to should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention but not limiting the scope of the invention; although be explained in detail the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
