Embodiment Construction

[0021] The components were prepared in the weight ratios shown in Table 1.

[0022] The weight proportion of table 1 embodiment 1~embodiment 3

[0023]

[0024] In the above examples, the hydrophobically modified alumina particles are prepared by soaking the alumina particles in the silane coupling agent KH-570, and the particle size range is 20-100 μm; the promoter is zinc naphthenate; The plasticizer adopts phthalates; the solvent adopts chloroform.

[0025] The preparation method is:

[0026] S1: Evenly disperse acrylic modified epoxy resin, liquid nitrile rubber, dicyandiamide, hexamethylenetetramine, and maleic anhydride in the solvent;

[0027] S2: Add polymethyl methacrylate, ethylene glycol dimethacrylate, silica sol, hydrophobically modified alumina particles, calcium carbonate, dolomite powder, bentonite, accelerator, and plasticizer to the mixture obtained in S1, Stir well;

[0028] S3: While stirring, heat up to 40-50°C, keep warm for 30 minutes, and let coo...

Abstract

The invention provides an adhesive for adhering ceramic and metal, belonging to the technical field of adhesives. The adhesive comprises the following raw materials by weight: 20-30 parts of acrylic-acid modified epoxy resin, 4-6 parts of liquid nitrile rubber, 2-4 parts of dicyandiamide, 2-3 parts of hexamethylene tetramine, 1-2 parts of maleic anhydride, 4-10 parts of polymethyl methacrylate, 3-7 parts of ethylene dimethacrylate, 4-8 parts of diaminodiphenyl sulfone, 10-15 parts of silica sol, 5-9 parts of hydrophobically modified alumina particles, 5-10 parts of calcium carbonate, 3-6 parts of dolomite powder, 2-4 parts of bentonite, 2-6 parts of accelerant, 1-3 parts of plasticizer and 40-60 parts of solvent. The adhesive provided by the invention has good adhering properties, is used for adhering ceramic and metal, has the shearing strength of more than 17MPa or more and has the shearing strength of more than 14Mpa after being damaged in the high-temperature environment.

Description

technical field [0001] The invention provides an adhesive, in particular relates to an adhesive used for connecting ceramics and metals, and belongs to the technical field of adhesives. Background technique [0002] Ceramics, metals, and polymer materials are known as the three major contemporary solid materials, each of which has its own advantages. Ceramics have good corrosion resistance, mechanical strength, and insulation properties; while metals have good toughness, electrical conductivity, and ease of processing. However, the brittleness of ceramics is relatively large, and the resistance to sudden temperature changes is not good, so it needs to be bonded with metals, which can effectively overcome these shortcomings. For example: especially in the field of aerospace, such as the connection of key components of aircraft and missiles. [0003] However, since ceramics and metals are two types of materials with different properties, there are differences in chemical and...
