preparation example Construction

[0036] Another aspect of the present invention provides a method for preparing glue that can be used for bonding glass and metal, at least including the following steps: weighing each material by weight, adding the materials to the stirring tank in sequence under normal temperature and pressure conditions Inside, use a mixer to disperse evenly to obtain the glue. Set stirring parameters: 300-1000 rev / min, stir for 10-50 minutes.

[0037] Through this preparation method, a kind of glue that can be used for bonding glass and metal can be prepared, which can realize the normal use in the thermal transfer process, and the firmness, yellowing resistance, and material application range will be improved, and it also has good water and water resistance. Alcohol, initial tack and anti-tack.

Embodiment 1

[0041]The first aspect of Example 1 provides a glue that can be used for bonding glass and metal, which is composed of the following raw materials in the weight ratio: E-10 modified hydroxyacrylic resin AC1171 37 parts, saturated polyester resin GW-807520 15 parts of xylene, 5 parts of vinyltriethoxysilane, 4.5 parts of N3390 curing agent, 10 parts of rosin, 8 parts of EP 2310 adhesion promoter, 0.5 parts of synde-137C defoamer.

[0042] The second aspect of Example 1 provides a method for preparing glue that can be used for bonding glass and metal, at least including the following steps: according to the above-mentioned proportion, each material is weighed by weight, and under normal temperature and pressure conditions, Put the materials into the stirring tank in turn, stir at a stirring speed of 500 rpm for 40 minutes to disperse them evenly, and obtain the glue.

Embodiment 2

[0044] The first aspect of Example 2 provides a glue that can be used for bonding glass and metal, which is composed of the following raw materials in the weight ratio: 45 parts of modified hydroxyacrylic resin ACR6624, 15 parts of saturated polyester resin GW-80751, two 20 parts of toluene, 4 parts of vinyltrimethoxysilane, 5.5 parts of N3375 curing agent, 6 parts of DAMA, 4 parts of EP2325 adhesion promoter, 0.5 parts of synde-137 defoamer.

[0045] The second aspect of Example 2 provides a method for preparing glue that can be used for bonding glass and metal, at least including the following steps: according to the above proportions, each material is weighed in parts by weight, and under normal temperature and pressure conditions, Put the materials into the stirring tank in turn, stir at a stirring speed of 800 rpm for 35 minutes to disperse them evenly, and obtain the glue.

Abstract

The invention provides glue capable of being used for bonding glass and metal and a preparation method of the glue. The glue is prepared from main body resin, auxiliary resin, a dissolving medium and a functional auxiliary agent. Hydroxyl modified acrylic resin is taken as a main body, the polyester resin is taken as an auxiliary body, tackifying resin is added, and an isocyanate closed curing agent is combined for reaction, so that the prepared glue solves the defect that existing glue in the industry is easy to yellow under the condition of a heat transfer process, and the integrity, the material application range, the initial adhesion, the adhesion resistance and the like of the product are improved; and the glue has potential application value in the heat transfer printing industry.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to thermal transfer glue, more specifically to a glue that can be used for bonding glass and metal and a preparation method. Background technique [0002] At present, the method used for the appearance identification of glass and some metal materials is mainly lamination and pasting, and the (integration) of the product is not very ideal. [0003] Related industries adopt a heat transfer process, that is, heat transfer the product pattern on glass and metal materials, so that the appearance and effect of the product are well expressed, and its resistance is also greatly improved, but the glue of this heat transfer process It is often realized by epoxy system, which is prone to problems such as yellowing and narrow application range of materials during processing. [0004] In view of the lack of product application fields, the needs of related industries and the amount of products u...
