Description
Technical Field
The invention relates to the field of bottle cap aluminum foil gaskets for packaging, in particular to aluminum foil paper coating bonding wax.
Background
The aluminum foil paper coating bonding wax is a temporary bonding material, needs to have good initial adhesion when the aluminum foil paper and the white cardboard are compounded, and can show good permanent adhesion at different temperatures. The aluminum foil paper coating bonding wax product needs to balance initial adhesion and permanent adhesion, and also needs to balance adhesion and removability, and has certain technical difficulties. In addition, the aluminum foil paper gasket is easy to soften in the high-temperature environment in the summer transportation process, the insufficient strength of the bonding wax causes the reduction of the bonding strength and the edge warping, and in the lower environment of the winter temperature, the high cohesive force causes the edge warping of the aluminum foil paper easily.
The aluminum foil paper coating bonding wax products sold on the market at present mainly have the problems that no product can simultaneously meet the requirement of being universal all the year round, the formula of the bonding wax needs to be adjusted according to seasons or a plurality of products are simultaneously mixed and used according to different proportions, so that a lot of inconvenience is brought to production of aluminum foil paper gasket production enterprises, and quality risks are brought to final client use. In addition, the existing adhesive wax for the aluminum foil paper coating is usually good in cohesiveness but not easy to remove completely, and the easily removed product is poor in cohesiveness, so that an aluminum foil paper coating adhesive wax product which is good in cohesiveness, high-temperature resistant, capable of meeting the requirement of being universal all the year round and easy to remove is required to be developed.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the adhesive wax for the aluminum foil paper coating, which solves the problems that like products in the market cannot be commonly used in four seasons, and the aluminum foil gasket is easy to generate raised edges in long-time transportation, storage and use in environments with the temperature higher than 60 ℃ in summer and lower than-20 ℃ in winter.
In order to achieve the technical purpose, the invention adopts the technical scheme that the adhesive wax for the aluminum foil paper coating comprises the following components in percentage by weight: 10-40% of wax, 10-40% of microcrystalline wax, 2-7% of polyolefin, 5-10% of random olefin copolymer, 0-10% of mineral oil, 10-30% of tackifier and 0.1-0.5% of antioxidant.
Wherein the wax is selected from one or more of paraffin wax, polyethylene wax and Fischer-Tropsch wax. The melting point of the paraffin is 56-74 ℃, the dropping point of the polyethylene wax is 90-100 ℃, and the melting point of the Fischer-Tropsch wax is 70-90 ℃.
Wherein the proportion of isoparaffin of the microcrystalline wax is not less than 80%, and the melting point of the microcrystalline wax is 67-92 ℃.
Wherein the viscosity average molecular weight of the polyolefin is 2000-60000.
Wherein the viscosity average molecular weight of the random olefin copolymer is 20000-50000.
Wherein the tackifier is petroleum resin, terpene resin, rosin resin and derivatives thereof.
