Abstract
The invention discloses a solvent type high-peeling-force high-temperature-and-humidity-resistant glue and a preparation method thereof, belonging to the technical field of glues. The glue is prepared by mixing 80-85% of MA50S, 0.8-1.2% of aziridine crosslinking agent and 15-20% of diluent, wherein MA50S is a two-liquid oily acrylate pressure-sensitive adhesive, and the diluent is methyl ethyl ketone which is commonly called methyl ethyl ketone. According to the invention, by adjusting the proportion of the monomer and the initiator in MA50S and adding the aziridine crosslinking agent, the use of other additives is reduced, the high temperature resistance of the glue is improved, and the cohesive strength of the glue is improved by adding quantitative methyl ethyl ketone, so that the glue does not generate the phenomena of denaturation, degumming, glue overflow, warping and the like at a high temperature of 85 ℃, and the peel strength reaches 1900g/inch to 2200 g/inch. The glue is simple in production process, saves materials and labor processing cost, and meets the energy-saving and environment-friendly requirement advocated by the state.
Description
Technical Field
The invention belongs to the technical field of glue, and particularly relates to solvent type high-stripping-force high-temperature-resistant high-humidity-resistant glue and a preparation method thereof.
Background
The acrylic glue is also called organic glass glue and PMMA glue. At present, the acrylic glue is an indispensable product, is widely popularized in the automobile industry, the electronic industry, the plasticizing industry and the hardware industry, and plays an important role in the glue industry. However, in the current industry and markets, many high-temperature glues have too many acrylic system glues, when the acrylic system glues are used, a pasted object is easy to displace in a high-temperature high-humidity environment, and in order to reduce poor displacement after the pasted object is attached, a solvent type glue with high peeling force, high-temperature high-humidity resistance and no displacement is provided.
Disclosure of Invention
The invention aims to provide a solvent type high-stripping-force high-temperature and high-humidity resistant glue and a preparation method thereof, and aims to solve the problems in the background art. In order to realize the purpose, the invention adopts the technical scheme that: a solvent type high-stripping-force high-temperature-resistant high-humidity-resistant glue and a preparation method thereof comprise the following raw materials in percentage by weight: MA 50S: 80% -85%, aziridine crosslinking agent: 0.8 to 1.2 percent of the total weight of the lubricant and 15 to 20 percent of the diluent. Wherein MA50S is two-component oil acrylic pressure-sensitive adhesive, which can be added with different types of cross-linking agent or auxiliary resin to change the performance of solution type high molecular polymer. The thinner is methyl ethyl ketone, commonly called methyl ethyl ketone, with a chemical formula of CH3COCH2CH3, and the methyl ethyl ketone is used as a thinner for glue because of various reactions easily occurring due to the carbonyl and active hydrogen adjacent to the carbonyl. By adding aziridine crosslinking agent into MA50S, the water resistance, chemical resistance, dry and wet rubbing resistance, surface anti-sticking property, coating fastness and adhesion on special substrate can be greatly improved.
A preparation method of solvent type high-stripping-force high-temperature and high-humidity resistant glue is characterized by comprising the following steps: the method comprises the following steps:
step one, carrying out solution polymerization on a monomer, an initiator and a solvent to obtain MA50S, blending MA50S, an aziridine crosslinking agent and a diluent, and mixing for 10-20 minutes to obtain glue;
step two, heating the glue to 90-110 ℃ and drying for 2-3 minutes;
and step three, placing the dried glue at the temperature of 35-40 ℃ for 72-85 hours.
According to the invention, by adjusting the proportion of the monomer and the initiator in MA50S and adding the aziridine crosslinking agent, the use of other auxiliary agents is reduced, the high temperature resistance of the glue is improved, and the cohesive strength of the glue is improved by adding quantitative methyl ethyl ketone, so that the glue does not generate the phenomena of denaturation, degumming, glue overflow, warping and the like at the high temperature of 85 ℃, and the peel strength reaches 1900g/inch to 2200 g/inch. The glue is simple in production process, saves materials and labor processing cost, and meets the energy-saving and environment-friendly requirement advocated by the state.
