Problems solved by technology

[0002] At present, paper and plastic film are usually used for packaging electronic components. Since plastic film is not recyclable, it will cause environmental pollution. Therefore, the use of recyclable and degradable paper and cardboard has good environmental protection significance, but ordinary packaging paper cannot Anti-static, also easy to burn, so the wrapper needs to be treated
The existing method is usually to compound packaging paper with metal foil plastic, but this kind of packaging is not easy to recycle, and it is easy to cause environmental pollution; there are also methods of coating and impregnating combined with antistatic agents, flame retardants and insulating agents , using a variety of additives for compounding, however, the packaging paper has a complex formula and a large number of components, and the interaction between different components is easy to cause functional failure
In addition, the existing packaging materials for electronic components are high in cost and poor in reusability

preparation example Construction

[0027] The present invention provides a preparation method of an insulating flame retardant for wrapping paper described in the above technical solution, comprising the following steps:

[0028] Mix and disperse dicyclohexenyl hypophosphite, nano silicon dioxide, carboxylated styrene-butadiene latex and silicone lubricant to obtain an insulating flame retardant for wrapping paper.

[0029] In the present invention, the mixing and dispersing is carried out under stirring conditions, the stirring speed is preferably 100-300r / min, more preferably 150-250r / min, and the time is preferably 5-60min, more preferably 20-50min , more preferably 25 to 40 minutes.

[0030] After the mixing and dispersing is completed, the present invention preferably further includes: filtering the obtained dispersed mixed liquid, and the mesh size of the mesh used for the filtering is 100 mesh. The invention removes ununiformly dispersed large-particle impurities by filtering to obtain a uniform insulat...

Embodiment 1

[0035] In parts by weight, the component distribution ratio of the insulating flame retardant for wrapping paper is:

[0036]

[0037] Mix and disperse the above-mentioned components in parts by weight, the dispersion speed is 300r / min, and the dispersion time is 50min to obtain a dispersion mixture, and then filter the dispersion mixture with a 100-mesh sieve to obtain an insulating material for wrapping paper. flame retardant.

Embodiment 2

[0039] In parts by weight, the component distribution ratio of the insulating flame retardant for wrapping paper is:

[0040]

[0041] Mix and disperse the above-mentioned components in parts by weight, the dispersion speed is about 200r / min, and the dispersion time is 30min to obtain a dispersion mixture, which is filtered through a 100-mesh screen to obtain an insulation barrier for wrapping paper. Fuel.

Abstract

The invention provides an insulating flame retardant for packaging paper as well as a preparation method and application of the insulating flame retardant, and belongs to the technical field of packaging. The insulating flame retardant for the packaging paper is prepared from the following components in parts by weight: 16 to 50 parts of dicyclohexenyl hypophosphite, 2 to 20 parts of nano silicondioxide, 5 to 20 parts of carboxylic butadiene-styrene latex and 15 to 25 parts of organic silicon lubricant. The insulating flame retardant for the packaging paper provided by the invention is simplein components, the components are not easy to interact with each other, and the service life is long; the insulating flame retardant for packaging paper provided by the invention is easy to recycle,and does not cause environmental pollution. The insulating flame retardant for the packaging paper is used for electronic parts, so that the packaging paper and paperboards for the electronic parts have flame retardance, antistatic property and insulating property, have good recycling and degrading properties, and are low in cost.
