[0003] Chinese patent application number 200980101125.0 and publication number CN102131640A provide a "flame retardant multilayer label", which includes a first layer containing a polymer matrix and a flame retardant - a top coat, a second layer - a base film and a second layer Three layers - an acrylic adhesive layer containing a flame retardant, the three layers work together to make a VTM-0 level (a burning level of a thin material in the US UL laboratory standard) halogen-free flame-retardant labels, of which the top coating Both the flame retardant in the layer and the adhesive layer use ammonium polyphosphate, which has a good flame retardant effect, but ammonium polyphosphate is an externally added inorganic solid flame retardant. First, the solid flame retardant is combined with the liquid adhesive or the top layer The compatibility of the paint is not good, which affects the appearance of the product. In addition, the addition of flame retardants mixed with acrylic pressure-sensitive adhesives reduces the initial viscosity and persistent viscosity of the pressure-sensitive adhesives. It is difficult to ensure its flame retardancy. Ensure that its pressure sensitivity meets the requirements
At the same time, the base film does not use flame-retardant materials, and it is difficult to make the overall flame-retardant grade of the label reach VTM-0 only by adding a flame-retardant top coat and adhesive layer.

Abstract

The invention discloses a preparation method for halogen-free flame retardant polyester labeled paper. The method is characterized in that the method comprises the following steps: adopting butyl acrylate, ethylhexyl acrylate, acrylic acid, hydroxyethyl acrylate, ethyl methacrylate, a phosphorus-containing flame retardant monomer, a solvent, an initiator, and the like as raw materials to prepare a phosphorus-containing flame retardant acrylic acid pre-polymerization resin; preparing a phosphorus-containing flame retardant acrylic acid pressure sensitive adhesive; uniformly coating the phosphorus-containing flame retardant acrylic acid pressure sensitive adhesive on a halogen-free flame retardant polyester thin film; compounding the polyacrylate pressure sensitive adhesive-coated halogen-free flame retardant polyester thin film and a polyester release film; and carrying out ripening to prepare the halogen-free flame retardant polyester label product. With the present invention, the flame retardant and pressure sensitive adhesion property, the appearance and the environmental protection quality of the whole label product can be effectively improved, and the halogen-free flame retardant polyester labeled paper can meet the performance requirement of VTM-0 grade flame retardation.

Description

technical field [0001] The invention belongs to a layered product-a preparation method of label paper, and relates to a preparation method of halogen-free flame-retardant polyester label paper. The label paper product prepared by the invention is suitable for product labels in places with specific requirements such as flame-retardant, fire-resistant and high-temperature resistant electrical appliances, household appliances, batteries, and transportation. Background technique [0002] At present, most of the label papers used in electronic appliances, home appliances, batteries and transportation industries are made of plastic film as the base material and coated with self-adhesive materials. Among them, polyester film is widely used as the base material of electronic and electrical labels due to its excellent water, oil, chemical resistance, insulation and certain high temperature resistance. Acrylic pressure-sensitive adhesive has the characteristics of good low temperatur...
