Problems solved by technology

The PVC adhesives in the prior art usually use PVC resin which is easy to obtain as the main resin. However, the solubility of PVC resin is poor, the amount of solvent required is large, and the durability of the adhesive force is not ideal. shorter lifespan
[0004] Especially in order to realize the recycling of PVC, there are currently some reports on recycling PVC plastic powder for the preparation of polyvinyl chloride plastic adhesives. Improvement, high recovery cost

Embodiment 1

[0030] Embodiment 1: a kind of polyvinyl chloride plastic adhesive, comprises the raw material of following parts by weight:

[0031]

[0032] For the preparation method of the polyvinyl chloride plastic adhesive of this embodiment, please refer to figure 1 shown, including the following steps:

[0033] S10), ethylene dichloride is introduced into the rubber barrel in advance, and ethylene dichloride is used as the primary dissolving solvent of PVC resin powder and CPVC resin powder;

[0034] S20), uniformly mixing PVC resin powder and CPVC resin powder to obtain dry blended resin;

[0035] S30), under stirring conditions, add the dry blended resin into the glue barrel, and use dichloroethane to primary dissolve the dry blended resin to obtain the primary dissolved adhesive. Preferably, in this step, the stirring time is not low In 1.5 hours, more preferably, the stirring time is 1.8-2.5 hours;

[0036] S40), under stirring conditions, add cyclohexanone and xylene in the...

Embodiment 2

[0037] Embodiment 2: the remaining technical solutions of this embodiment 2 are the same as embodiment 1, and the difference is that this embodiment 2 proposes a polyvinyl chloride plastic adhesive, including the raw materials of the following parts by weight:

Abstract

The invention discloses a polyvinyl chloride plastic adhesive, which comprises the following raw materials in parts by weight: 10-20 parts of PVC resin; 10-20 parts of CPVC resin powder; 30-40 parts of cyclohexanone; 30-40 parts of xylene 60-70 parts of dichloroethane; the present invention also relates to the preparation method of the polyvinyl chloride plastic adhesive, adopting CPVC resin powder and PVC resin to carry out dry mixing to obtain dry mixed resin, adopting dichloroethane as dry The primary dissolving solvent of mixed resin, dichloroethane realizes the rapid dissolution of CPVC resin powder in dry mixed resin, and after obtaining the primary dissolved adhesive, cyclohexanone and xylene are used to realize the dissolution of the primary dissolved adhesive again. Ultimate dissolution, less solvent consumption, no need to add additional additives, and the preparation process is simple, more importantly, the polyvinyl chloride plastic adhesive product prepared by the present invention has very excellent adhesion and durability It is very suitable as a large-scale preparation process route for high-end polyvinyl chloride plastic adhesive products.

Description

technical field [0001] The invention relates to the field of adhesive preparation, in particular to a polyvinyl chloride plastic adhesive, and also relates to a preparation method of the polyvinyl chloride plastic adhesive. Background technique [0002] Polyvinyl chloride plastic is widely used because of its light weight, high strength, excellent corrosion resistance, and good durability. In order to achieve the bonding application of polyvinyl chloride plastics, it is necessary to configure and consume a large amount of corresponding polyvinyl chloride plastic adhesives (commonly known as PVC adhesives). Therefore, the market capacity of polyvinyl chloride plastic adhesives is huge. of. [0003] Specifically, the raw materials of existing polyvinyl chloride plastic adhesives usually consist of main resin, solvent and additives. Among them, the adhesive force and performance of polyvinyl chloride plastic adhesive mainly depend on the main resin. The performance of the mat...
