Embodiment 1

[0012] Embodiment 1: a kind of using method of aluminum acetylacetonate, the method comprises the steps:

[0013] 1) The plastic substrate is chemically pretreated, and the treated substrate will produce -OH, -COOH, -NH 2 the active group;

[0014] 2) adding aluminum acetylacetonate to the acrylic pressure-sensitive adhesive under stirring conditions, the amount of aluminum acetylacetonate being added is 0.1% of the weight of the acrylic pressure-sensitive adhesive;

[0015] 3) Apply the pressure-sensitive adhesive added with aluminum acetylacetonate in step 2) on the substrate at 70-75°C, and then vacuum-dry.

[0016] The aluminum acetylacetonate used in the present invention is a colorless crystalline powder with a purity of 99.9% and an aluminum content of 8.0-8.6%, soluble in benzene, toluene, xylene, methanol, and insoluble in water.

Embodiment 2

[0017] Embodiment 2: basically the same as Example 1, the difference is that the addition of aluminum acetylacetonate is 0.3% of the weight of the acrylic pressure-sensitive adhesive, and the temperature required to smear the pressure-sensitive adhesive containing aluminum acetylacetonate on the substrate At 75-80°C.

Embodiment 3

[0018] Embodiment 3: It is basically the same as Embodiment 1, except that the substrate used is a metal substrate, and the amount of aluminum acetylacetonate added is 0.2% of the weight of the acrylate pressure-sensitive adhesive.

Abstract

The invention discloses an application method of aluminum acetylacetonate, and the method comprises the following steps: 1) performing chemical pretreatment of a substrate to allow the treated substrate to generate active groups of -OH, -COOH, -NH2; 2) adding aluminum acetylacetonate into an acrylate pressure sensitive adhesive under stirring with an adding amount of aluminum acetylacetonate being 0.1-0.3% of the weight of the acrylate pressure sensitive adhesive; 3) coating the pressure sensitive adhesive added with aluminum acetylacetonate obtained in step 2) onto the substrate at 70-80 DEG C, and performing vacuum drying. The advantage of the invention is that the adhesion of the acrylate pressure sensitive adhesive on the substrate is increased.

Description

technical field [0001] The invention relates to a method for using an auxiliary agent, in particular to a method for using aluminum acetylacetonate. Background technique [0002] Pressure-sensitive adhesive is the abbreviation of pressure-sensitive adhesive, which is a kind of adhesive that is sensitive to pressure; it is mainly used to prepare pressure-sensitive tape; pressure-sensitive adhesive can be divided into rubber type and resin type according to the composition of the main resin. The rubber type can be divided into natural rubber and synthetic rubber; the resin type mainly includes acrylic, silicone and polyurethane. If the pressure-sensitive adhesive is not handled properly during use, degumming and other phenomena will occur, which will inevitably affect the quality of the product. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method for using alum...
