Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with examples.

[0015] The foregoing description and the following examples are intended to disclose and illustrate the present invention, and the specific amounts and combinations of the ingredients described herein are not intended to limit the scope of the present invention defined by the claims.

[0016]

[0017] To prepare test specimens, grit-blasted steel sheets were degreased with perchlorethylene vapor and dried. The steel sheet is prepared according to the requirements of GB / T7760-2003, with a thickness of 1.5mm±0.1mm. If plastic sheets or other sheets are used, the thickness is appropriately increased. The width of the steel sheet is 25mm±0.1mm, and the length is 60mm±1mm. Before applying the adhesive, draw a straight line 12.5mm away from one end of the steel sheet, and then apply 0.03-0.04g of adhesive on the glued surface of each steel sheet.

[0018] Dry the steel sheet coated wit...

Abstract

The invention discloses a natural rubber / butadiene styrene rubber metal HTV (Hot Vulcanization) adhesive, and relates to a rubber vulcanization adhesive. The natural rubber / butadiene styrene rubber metal HTV adhesive is prepared from the following components in percentage by weight: 1 to 2 percent of halogenated rubber, 18 to 22 percent of isocyanate, 9 to 12 percent of epoxy resin and the balance of solvent; or the natural rubber / butadiene styrene rubber metal HTV adhesive is prepared from the following components in parts by weight: 0.5 to 2.5 percent of halogenated rubber, 15 to 25 percent of isocynate, 7 to 25 percent of epoxy resin and the balance of solvent. The natural rubber / butadiene styrene rubber metal HTV adhesive disclosed by the invention contains no nitro compounds or lead salt, is used for adhering natural rubber or butadiene styrene rubber to metal through an HTV mode, and has good adhesion effect and low toxicity.

Description

technical field [0001] The invention relates to a rubber vulcanization adhesive, in particular to a natural rubber / styrene butadiene rubber metal heat vulcanization adhesive. Background technique [0002] Shock absorption is widely used in automobiles, such as subframe bushings, hydraulic bushings, crankshaft torsional shock absorbers, and dynamic shock absorbers. Most of these components are made of metal, and by bonding rubber on the metal surface, a good shock absorption effect can undoubtedly be achieved. [0003] There are a variety of rubber-to-metal adhesives on the market today. For example, CN93114420.5 discloses a single-coat rubber-metal adhesive. The adhesive contains halogen-containing polyolefin, aromatic nitroso compound, polymaleimide compound and metal oxide. Another example is CN200710188735.1 which discloses an adhesive for elastomers. The adhesive comprises at least one crosslinking agent: polynitroso compounds, polynitroso precursors, and mixtures th...
