The invention belongs to the technical field of adhesives, and particularly relates to a high-impact-resistance acrylate structural adhesive. The high-impact-resistance acrylate structural adhesive contains rigid functional groups provided by hydrogenated bisphenol A and methacrylate functional groups which can enhance the curing pull strength and impact resistance. The toughening resin is added to greatly enhance the impact resistance. The high addition percent of the curing agent in the component B can ensure the whole system to quickly perform reaction and curing. After room curing is performed for 3-5 minutes, 70-DEG C hot pressing only takes 60 seconds. The high-impact-resistance acrylate structural adhesive has high impact resistance, can pass the disk knife test, and can still keep high bonding power after being cut a little. The structural adhesive has high forward pull strength, and the pull force test proves that the pull force at the copper nail is generally required to be greater than 20kg or the copper nail can shed. The structural adhesive has high temperature resistance and high humidity resistance, and the strength does not obviously decrease when the structural adhesive is at 60 DEG C under the 90% humidity condition for 7 days.

The invention provides a hot melt adhesive composition and a preparation method thereof and further provides a hot melt adhesive heat-conducting strip and a preparation method thereof based on the hot melt adhesive composition. The hot melt adhesive composition at least comprises, by weight, 6 to 9 parts of thermoplastic resin with a softening point of 85 to 120 DEG C, 0.40 to 0.60 parts of a tackifier and 73 to 110 parts of a heat-conducting particle.

The disadvantages of easy flowing and deformation of heat-conducting strips in the prior art are overcome. Moreover, the heat-conducting strip provided by the invention has low thickness, so the heat conduction performance of the heat-conducting strip is improved.
