Problems solved by technology

The double-sided tapes on the market have poor weather resistance, and are generally only used at room temperature. At low temperatures, the initial adhesion is low, and at high temperatures, there will be problems such as poor stickiness.
At present, the existing acrylic tapes on the market cannot meet the requirements of wide temperature range, high performance and low cost, so the development of such a double-sided tape for carton bonding is extremely urgent

Embodiment Construction

[0021] Below in conjunction with embodiment the present invention is described in further detail.

[0022] An acrylic adhesive composition, consisting of the following raw materials and parts by mass:

[0023]

[0024] Wherein, the modifying agent is at least one of dioctyl adipate and butyl phthalate. The isocyanate curing agent is at least one of toluene diisocyanate, isophorone diisocyanate, hexamethylene diisocyanate, and 4,4'-dicyclohexylmethane diisocyanate.

[0025] The preparation method of the above-mentioned acrylate adhesive composition is as follows: according to the above-mentioned mass parts, the solution obtained by mixing the tackifying resin and the solvent is added to the acrylic adhesive, stirred evenly, and then the modifier is added, and stirred After 10-20 minutes, add the curing agent and stir rapidly for 20-30 minutes to obtain the desired acrylate adhesive composition.

[0026] During the performance test, the above-mentioned acrylic adhesive comp...

Abstract

The invention relates to an acrylic adhesive composition and a preparation method thereof. The acrylic adhesive composition consists of the following raw materials and their parts by mass: 100 parts of acrylic adhesive, a tackifying resin and a solvent 1.5-15.0 parts, 0.5-3.0 parts of isocyanate curing agent, 0.5-10 parts of modifier; wherein, the modifier is at least one of dioctyl adipate and butyl phthalate. Compared with the prior art, the present invention has the advantages that: the acrylic adhesive composition of the present invention has good initial adhesion and long-lasting adhesion, and still maintains high performance when the temperature range is large; the adhesive The adhesive tape made of the adhesive composition can meet the technical requirements of the express delivery industry for packaging cartons in terms of bonding strength (carton tearing rate), stickiness, initial tack and weather resistance to corrugated boxes, and the cost of the adhesive tape is low.

Description

technical field [0001] The invention relates to the field of acrylic adhesives, in particular to an acrylic adhesive composition and a preparation method thereof. Background technique [0002] According to statistics, in 2016, the number of express parcels in my country exceeded 31.3 billion, and the number of corrugated boxes used behind them was as high as 46 million tons, accounting for one-third of the world's total. As an indispensable part of modern logistics, packaging cartons bear the important responsibility of packaging, protecting products, and aesthetics. The physical performance indicators of packaging cartons become the basis for their quality evaluation. Traditional cartons are packaged with transparent single-sided tape "wrapping", which is not only inconvenient to operate, but also wastes a lot, and is not easy to degrade, causing great environmental pollution. The new environment-friendly cartons appearing on the market are sealed inside with double-sided ...
