Abstract

The invention relates to a film coating binder for engineering machinery. The film coating binder comprises additives and a carrier and is prepared from the raw materials in percentage by weight: 0.5%to 6% of river mud, 10% to 35% of resin, 1% to 10% of filler, 0 to 3% of calcined bastard coal, 0 to 2.5% of steel slag, 5% to 20% of silicon micropowder, 10% to 20% of setting retarder and 30% to 60% of maifanite. The product prepared by a method is high in peeling strength and simple in binding process and can replace a hot-melt adhesive, and the production cost is reduced.

Description

technical field [0001] The invention discloses a film bonding adhesive for engineering machinery. Background technique [0002] Known EVA foam material is prepared by ethylene-vinyl acetate copolymer foaming, and polarity is low, and PU (polyurethane) film belongs to high polarity material, and the interfacial bonding of the two is strong and difficult, and in prior art, mainly Hot-melt adhesives are used to bond the two to achieve lamination of the two. However, the cost of hot-melt adhesives is relatively high. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a film bonding adhesive for construction machinery, which has high peel strength and simple bonding process, can be used instead of hot melt, and reduces production costs. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a film bonding adhesive for engineering machiner...
