Problems solved by technology

[0005] The main component of existing BOPP synthetic paper coatings is acrylic resin emulsion, which is expensive and has certain problems in its combination with the film base: First, due to the low surface tension of synthetic paper, it cannot be well combined with the primer coating ; secondly, the curing time of acrylic resin emulsion coating is long, and production efficiency is low, can't meet high-speed production demand; Again, because its price is expensive, has increased production cost, reduces the economic benefit of enterprise; In addition, in the production process, because time-consuming It consumes more energy and does not conform to the concept of environmental protection development

Embodiment 1

[0029] Take 20% pure acrylic emulsion, 1.2% ammonium zirconium carbonate, 0.6% aziridine, 1.4% polyether defoamer, and 1% fatty acid ester. At room temperature, add pure acrylic emulsion, turn on the stirring, the speed is 400rpm, add a certain amount of water, stir for 10min, then add aziridine, the stirring speed is 200rpm, stir for 40min, then add ammonium zirconium carbonate, the speed is 250rpm, stir for 10min, Then add fatty acid ester, stir at 300rpm, stir for 15min, finally add polyether defoamer, continue to stir at 200rpm for 40min, until the mixture is evenly mixed, and then adjust the solid content of the required primer by adding water. The solid content of the paint is 14.5%, and the viscosity of the paint (coating 4 cups) is 11.0''. The coating is then coated on synthetic paper with a coating weight of 4.0g / m 2 Then put it in a 90°C oven and dry it for 1.5min to make it completely cured. The measured surface tension value is 46, and the surface fastness is OK ...

Embodiment 2

[0031] Take 25% of silicon-acrylic emulsion, 1.5% of ammonium zirconium carbonate, 0.8% of aziridine, 1.2% of polyether defoamer, 1.2% of fatty acid ester, add silicon-acrylic emulsion at room temperature, turn on the stirring, rotate at 300rpm, add A certain amount of water, stirred for 20min, then added aziridine, stirred at 250rpm, stirred for 45min, then added ammonium zirconium carbonate, stirred at 300rpm, stirred for 20min, then added fatty acid ester, stirred at 400rpm, stirred for 20min, then added polyether For defoaming agent, continue to stir at a stirring speed of 300rpm for 45min until the stirring and mixing are uniform, and then adjust the solid content of the required primer by adding water. The solid content of the paint is 16.0%, and the viscosity of the paint (4 cups of paint): 11.3''. Then the coating is coated on the synthetic paper, the coating amount is about 4.3g / m2. Then put it in an oven at 90°C and dry it for 1.2 minutes to make it completely cured...

Embodiment 3

[0033] Take 30% of styrene-acrylic emulsion, 1.8% of ammonium zirconium carbonate, 1.1% of aziridine, 0.9% of polyether defoamer, 1.5% of fatty acid ester, add silicon-acrylic emulsion at room temperature, turn on the stirring, rotate at 500rpm, add A certain amount of water, stirred for 15min, then added aziridine, stirred at 350rpm, stirred for 50min, then added ammonium zirconium carbonate, stirred at 400rpm, stirred for 25min, then added fatty acid ester, stirred at 350rpm, stirred for 25min, then added polyether For defoaming agent, continue to stir at a stirring speed of 250rpm for 50min until the stirring is uniform, and then adjust the solid content of the required primer by adding water. The solid content of the paint is 17.5%, and the viscosity of the paint (4 cups of paint): 11.5''. Coat the prepared primer coating on the synthetic paper, the coating amount is about 4.6g / m2. Then place it in a 90°C oven and dry it for 1 min, when the coating is completely cured. T...

Abstract

The invention discloses BOPP synthetic paper primer coating and a preparation method thereof. The primer coating also comprises the following components in percentage by mass: 20-40% of an acrylic resin emulsion, 0.5%-2% of a water repellent agent, 0.5%-2% of a cross-linking agent, 0.5%-2% of a defoaming agent and 0.5%-2% of a lubricant. The coating is simple to prepare. The selected acrylic resinemulsion is water-dilutable acrylic acid, and the adhesion between the coating and base film is promoted through the physical and chemical properties and the mechanical action between the synthetic paper base film and the coating; in addition, the aziridine cross-linking agent is selected as a bi-component cross-linking agent, can react with carboxyl and hydroxyl at room temperature to form an independent net structure, and is high in reaction speed and obvious in effect. Therefore, the problem of combination between the low surface tension value of the synthetic paper and the high surface tension value of the coating is solved, the coating is good in spreadability and high in curing speed, the production speed is remarkably increased, the paper performance is excellent, the trend of environmental protection is met, and development and popularization of the BOPP synthetic paper are facilitated.

Description

technical field [0001] The invention relates to a primer for BOPP synthetic paper and a preparation method for the paint. [0002] technical background [0003] Synthetic paper used to be known as chemical film paper, polymer paper, etc. It uses polymer compounds as the main raw material, adopts certain processing methods and production techniques, and its finished products are similar in appearance to ordinary fiber paper, but in performance A new type of plastic paper that is superior to lignocellulose paper. [0004] BOPP synthetic paper is a kind of synthetic paper. The production of BOPP synthetic paper in my country is relatively short, and it was mainly imported from abroad in the early stage. Due to the excessive competition of conventional products, a small number of domestic BOPP companies started to develop and develop it. For BOPP synthetic paper, because its surface is a non-polar surface, its surface tension value needs to reach 38. If its surface tension value...
