Abstract
The invention discloses a spot welding sealant for car body welds. The sealant is composed of the following ingredients, by weight, 12-23 parts of epoxy nitrile rubber toughened epoxy resin, 3-6 parts of water-extract from mulberry leaves, 5-10 parts of black rice anthocyanins, 20-30 parts of multiwalled carbon nanotube-organic montmorillonite synergistic toughened epoxy resin, 15-25 parts of organosilicone-coated rosinyl epoxy resin microcapsule and 2-7 parts of a surfactant. Through the above method, the spot welding sealant has good construction technique. During spot welding, spot welding strength will not be influenced, and corrosion of metal will not be caused.
Description
Technical field
The present invention relates to seal gum field, particularly relate to a kind of sealant for spot welding for vehicle body weld seam.
Background technology
Tackiness agent and sealing agent not only solve " three leak " problem of automobile, but also play the effect strengthening vehicle structure, heat-insulating and shock-absorbing and internal and external ornament, simplify automobile manufacturing process simultaneously, at automotive light weight technology, save energy and reduce the cost, increase the service life in play an increasingly important role.Sealant for spot welding is coated on the overlapping part of steel plate in advance, and some postwelding spline joint gap, ensures sealing, prevent corrosion.
But the sealant for spot welding used at present does not possess good construction technology, when carrying out spot welding, affects spot welding intensity sometimes, sometimes also can cause corrosion of metal.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of sealant for spot welding for vehicle body weld seam, possesses good construction technology, when carrying out spot welding, can not affect spot welding intensity, also can not cause corrosion of metal.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of sealant for spot welding for vehicle body weld seam, sealing glue is epoxy resin toughened by epoxy group(ing) paracril, mulberry leaf water, black rice husk anthocyanogen, multi-walled carbon nano-tubes-organo montmorillonite coordination plasticizing epoxy resin, silicone covering rosin epoxy resin microcapsule and tensio-active agent, the weight content of its each component is: epoxy resin toughened 12 ~ 23 parts of epoxy group(ing) paracril, 3 ~ 6 parts, mulberry leaf water, black rice husk anthocyanogen 5 ~ 10 parts, multi-walled carbon nano-tubes-organo montmorillonite coordination plasticizing epoxy resin 20 ~ 30 parts, silicone covering rosin epoxy resin microcapsule 15 ~ 25 parts, 2 ~ 7 parts, tensio-active agent.
In a preferred embodiment of the present invention, described tensio-active agent is nonionogenic tenside.
In a preferred embodiment of the present invention, described nonionogenic tenside is the smooth or polysorbate of glycerin fatty acid ester, lipid acid sorb.
In a preferred embodiment of the present invention, in described multi-walled carbon nano-tubes-organo montmorillonite coordination plasticizing epoxy resin, the weight proportion of multi-walled carbon nano-tubes and organo montmorillonite is 1:10-20.
The invention has the beneficial effects as follows: the present invention possesses good construction technology, when carrying out spot welding, spot welding intensity can not be affected, also can not cause corrosion of metal.
