Embodiment 1-6

[0028] Prepare the water-based PP adhesive according to the ratio in Table 1:

[0029] Table 1

[0030]

[0031] The preparation method is as follows:

[0032] (1) Mix the water-based chlorinated polypropylene (CPP) emulsion and the water-based thermoplastic resin emulsion uniformly under the condition of 500-1000r / min;

[0033] (2) Add the surfactant and the organic solvent dropwise to the mixed solution described in (1) under the condition of 500-1000r / min, and disperse for 20min after the dropwise addition is completed;

[0034] (3) Slowly add deionized water to the mixed liquid obtained in step 2, and continue to disperse for 20-60 minutes.

[0035] After preparing the adhesive, test its adhesion on the PP substrate and its own storage stability. The specific performance test methods and results are as follows:

[0036] 1. Initial adhesion

[0037] Coat the adhesive on the PP substrate with a wire bar coater (20 μm), bake at 60°C for 6 minutes or place it at room te...

Abstract

The invention discloses a water-borne PP adhesive and a preparation method thereof and belongs to the technical field of adhesives. The water-borne PP adhesive per 100 g comprises the following raw materials: 4-45 g of a water-borne chlorinated polypropylene emulsion, 4-45 g of a water-borne thermoplastic resin emulsion, 0.05-2 g of a surfactant, 0-10 g of an organic solvent and the balance of deionized water, wherein the solid contents of the water-borne chlorinated polypropylene emulsion and the water-borne thermoplastic resin emulsion are 30-40%; serving as an adhesion promoter, the water-borne chlorinated polypropylene emulsion is compounded with water-borne thermoplastic resin, so that the effect of binding and adhering to a polypropylene substrate is remarkably improved. The water-borne PP adhesive contains an extremely small quantity of the organic solvent and takes water as a main dispersion medium, environmental harms caused by the use of the PP adhesive are greatly reduced, and the product security in the transport and use processes is improved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-based PP adhesive and a preparation method thereof. Background technique [0002] As one of the five general-purpose plastics, polypropylene (PP) is non-toxic, tasteless, wide source, low price, simple manufacturing process, excellent mechanical properties, heat resistance and chemical stability, and is widely used in industrial products, daily necessities, Automotive, packaging materials and other fields. However, since PP is a non-polar polymer with low surface tension and high crystallinity, compared with general plastic products, it is difficult to adhere. In order to improve the adhesion to the surface of PP, the surface is generally treated by flame treatment, plasma treatment, radiation, microwave and corona discharge to increase its surface energy. However, these treatment methods will be restricted to varying degrees due to the cost and the complexity of the ...
