Preparation technique of solid universal glue

Abstract

The invention discloses a preparation process for a solid all-purpose adhesive. The preparation process comprises the following steps: 1): filtering solid all-purpose adhesive slurry through a 80 to 100-mesh sieve; 2): pressurizing and spaying the solid all-purpose adhesive slurry obtained in the step 1) onto a carrier film with the spraying thickness of 1 to 2 mm; 3): sending the carrier film which is coated with the solid all-purpose adhesive slurry and is obtained in the step 2) into an oven for drying, and setting the temperature in the oven at 40 to 85 DEG C and the drying time for 1 to 5 minutes; 4): adopting a film laminator to press a top film on the solid all-purpose adhesive layer of the carrier film obtained in the step (3) so as to prepare the filmily solid all-purpose adhesive, and setting the laminating pressure at 60 to 80N / cm<2> and the laminating time at 5 to 30 seconds; and 5): carrying out the edge cutting and sealing treatment of the solid all-purpose adhesive obtained in the step 4). The product prepared by the process is filmily and can be made into any shape as required by customers; and in addition, the solid all-purpose adhesive has even painting, and quick and convenient construction.

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.
