Preparation technique of solid universal glue

Abstract

The present invention discloses a process for preparing a solid versatile adhesive, which comprises the steps of: 1) filtering a slurry of the solid versatile adhesive by a filter screen with 80-100 mesh; 2) spraying the slurry of the solid versatile adhesive after filtration from step 1) onto a base film under pressure to a thickness of 1-2 mm; 3) transporting the base film coated with the slurry of the solid versatile adhesive from step 2) to an oven at 40-85 ºC and drying for 1-5 min; 4) laminating a top film to the solid versatile adhesive layer on the base film from step 3) by using a film laminator under a pressure of 60-80 N / cm2 for 5-30 s, to obtain a solid versatile adhesive in a thin film form; 5) subjecting the solid versatile adhesive from step 4) to edge-cutting and sealing. The product made by the present process is in the form of film, which enables the end user to manufacture it in any shape as required. Such product is uniformly coated and can be used quickly and conveniently.

Description

technical field [0001] The invention relates to a preparation process of a universal glue, in particular to a preparation process of a solid universal glue. Background technique [0002] At present, the adhesives commonly used in the decoration industry at home and abroad are traditional solvent-based and water-based universal adhesives, but the stability of water-based universal adhesives is not widely used, and there are two main types of solvent-based universal adhesives, one is SBS The other is neoprene universal glue. Although SBS universal glue has the advantages of environmental protection, low price, high solid content, large painting area, long development time and easy construction compared with neoprene universal glue, its There are many deficiencies like neoprene, such as: [0003] 1. A large amount of solvent is wasted during production, generally containing 64% to 77% of solvent. During construction and drying, these solvents are not recycled but directly disc...

Problems solved by technology

[0003] 1. A large amount of solvent is wasted during production, generally containing 64% to 77% of solvent. During construction and drying, these solvents are not recycled but directly discharged into the atmosphere, which not only consumes energy but also causes environmental pollution;

[0004] 2. Iron drums are required for transportation and packaging, which makes transportation and storage extremely troublesome;

[0005] 3. The use of iron drums not only increases the cost of the product, but also causes environmental pollution caused by discarded iron drums. Therefore, the development of a solid-state universal adhesive with a simple structure and easy use has been put on people's research agenda.
