Embodiment Construction

[0019] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with specific examples.

[0020]

[0021]

[0022] As shown in the three examples above, the preparation method is as follows:

[0023] Accurately weigh various raw materials according to the proportion of the formula, and then put them into the light curing equipment in order to prepare the liquid UV curing sealant.

[0024] The relevant physical properties of the above three examples were tested, such as viscosity, surface dry time, hardness after curing, elongation at break, service temperature range and oil resistance, etc. It can be seen that the products obtained in the three examples all have Excellent characteristics in all aspects.

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 [0001] The invention relates to the technical field of sealant, in particular to a liquid UV curing sealant which can replace the solid sealing ring of an automobile fuel tank cap and a preparation method thereof. Background technique [0002] At present, the sealing of automobile fuel tank caps is mainly realized by solid sealing rings. The disadvantages of existing solid sealing rings are 1) the production of fuel tank caps of different specifications must be molded, the cost is high, and the uniform applicability is poor; 2) there is no adhesion to materials, The matching accuracy is high. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention cooperates with liquid sealing technology to develop a single-component UV-curable sealant that improves production efficiency and reduces production costs, especially for the reliability and corrosion resistance of automotive fuel tank cap sealing. The t...
