一分彩Modification analysis of neoprene anticorrosive tape
一分彩 The modification of CR polyethylene adhesive tape with tackifying resin leads to the following conclusions: 1) In order to improve the initial adhesion strength of CR polyethylene adhesive tape, a tackifier must be used; Adding a tackifier can greatly improve its applicability; (3) the use of a high softening point tackifier can improve the CR polyethylene adhesive tape's adhesive strength and the heat resistance of the film; (4) in order to take into account the CR polymer Adhesiveness and processability of vinyl adhesive tape can achieve better results with mixed tackifiers.
一分彩Choose CR01 and resin RE01 and RE04 to obtain polyethylene adhesive tape with good comprehensive performance.
一分彩The performances of two different systems of neoprene polyethylene adhesive tape and polyurethane polyethylene adhesive tape were studied, and it was found that the two types of polyethylene adhesive tapes were used in combination because of the high degree of crosslinking, adhesion and heat resistance. Improved properties, suitable for bonding aluminum alloy and cotton fabrics.
一分彩It was found that in actual production, in order to improve the process performance of polyethylene adhesive tapes and reduce production costs, some general-purpose neoprene rubbers such as LDJ2121 neoprene or LDJ2120 neoprene can be appropriately blended. The quality of the adhesive tape does not have much impact.In some aspects, the quality has been improved, and the wetting effect of the polyethylene adhesive tape on the bonding surface and its coating uniformity have been improved.
一分彩Adhesive neoprene as the main component, modified with tert-butyl phenolic resin, toluene, gasoline, ethyl acetate as a mixed solvent, and supplemented with appropriate additives to produce a neoprene strong polyethylene adhesive tape with excellent properties This product has high bonding strength, outstanding low temperature resistance, and does not freeze at -20 ° C, especially suitable for use in northern regions.1 In addition, this product also overcomes the common glue layering, low temperature gel, and storage period of common products. Shortcomings
In addition, there is much work to directly improve the quality of CR rubber itself.
Introduced a series of directly dissolvable adhesive CR adhesives. This adhesive has better high temperature adhesive properties than traditional varieties, and its spraying and brushing properties are also better. Because it does not need to be pre-cured, the rubber can make polyethylene Adhesive tape preparation time is shortened by 40%, which can save energy and reduce solvent volatility. Due to different grades of viscosity, the effective time, dissolution characteristics and solvent amount of polyethylene adhesive tape can be controlled. Aluminum foil anticorrosive adhesive tape
