Embodiment Construction

[0017] Production process step of the present invention is:

[0018] A. Production of temperature-sensitive release adhesives; temperature-sensitive release adhesives are multi-component acrylate copolymer emulsions; 85 kg of alkoxysilane acrylate or methylol acrylamide mixed monomers, imidazole curing catalysts or polyisocyanate high temperature Curing agent 3kg, azodicarbonamide or p-toluenesulfonic acid hydrazide foaming agent 4kg, plastic antioxidant (commercially available product, select compound antioxidant: hindered phenol compound with phosphite, thioester) material) 0.3kg, plasticizer (for commercially available products, choose electrical grade dioctyl phthalate) 0.3kg and mix well to form a temperature-sensitive peeling adhesive, and fillers (light calcium carbonate or talc can also be added Powder) 0.3kg and an appropriate amount of coloring material.

[0019] B. Coating the peeling layer: coating the silicone oil on one side of the polyester film is the peeling ...

Abstract

The invention discloses a production process of a temperature-sensitive stripping membrane. The production process comprises the following steps of: A, producing a temperature-sensitive stripping bonding agent; B, processing a stripping layer: coating organic silicon oil onto one face of a polyester film to obtain a stripping layer; C, coating a temperature-sensitive stripping layer: coating the temperature-sensitive stripping layer bonding agent onto one surface of a substrate; and D, compounding and calendaring: compounding and calendaring the stripping layer onto the substrate which is coated with the temperature-sensitive stripping bonding agent, bonding one surface of the stripping layer which is coated with organic silicon oil with one surface of the substrate which is coated with the temperature-sensitive stripping bonding agent, and coiling. The production process has the advantages: during use, a special temperature-sensitive stripping bonding agent is foamed by heating to a specified temperature, and adhesive force of an adhesive belt disappears instantly, so that stripping is realized. Natural stripping can be realized without stressing, so that workpieces are not damaged or polluted, labor face is saved, conventional cleaning operation is avoided, and the utilization ratio of raw materials is increased.

Description

technical field [0001] This invention relates to the field of temperature-sensitive release membranes, technical background [0002] Thermal release film is a type of adhesive tape that loses its stickiness when the ambient temperature rises. In various manufacturing processes of electronic products, it has a great effect on automation and labor saving, and is widely used in: 1. Transmission: transmission of chip devices in the production of automated electronic products, transmission of piezoelectric devices in electrode printing, and hair diodes It is used for the transmission of the pickling treatment of the pins, and is used as a conveyor belt in production. 2. Protection: protection of lead frame punching, cover protection during pickling, and lead frame plating protection. 3. Temporary fixation: Temporary fixation of parts, temporary fixation during cutting, temporary fixation during grinding and polishing, etc. Due to the unique performance of the temperature-sensi...
