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 to 20 parts of CPVC resin powder; 30 to 40 parts of cyclohexanone; 30 to 40 parts of xylene; 60 to 70 parts of dichloroethane. The invention also relates to a preparation method of the polyvinyl chloride plastic adhesive. CPVC resin powder and PVC resin are subjected to dry mixing to obtain dry mixed resin; dichloroethane is used as a primary dissolving solvent of the dry-mixed resin; dichloroethane is used for rapidly dissolving the CPVC resin powder in the dry-mixed resin; after the primary dissolving adhesive is obtained; ultimate dissolution of the primary dissolving adhesive is realized through cyclohexanone and xylene, the preparation method has the advantages that the amount of consumed solvent is small, and extra additives are not required to be added; the preparation process is simple, more importantly, the polyvinyl chloride plastic adhesive product prepared by the method has very excellent adhesive force durability, and is very suitable for being used as a large-scale preparation process route of a high-end polyvinyl chloride plastic adhesive product.
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...
