Can acrylic be used as an adhesive? |
Public date:2019-11-20 Hits:4153 |
At home, many families simply paint on the wall, and the TV background wall is the same. In fact, the TV background wall can be very artistic and not very gorgeous, and there will be no feeling of being overwhelmed. We will use the adhesive when decorating the TV background wall. Can acrylic be used as an adhesive? Let's take a look together.
First, how to improve the adhesion of acrylate adhesive to pp
Resolved from synthetic technology:
1. Acetoacetoxyethyl methacrylate (AAEM) - modified for acrylic resins and unsaturated polyester resins.
2. Diacetone acrylamide (DAAM) - modified for waterborne acrylic resins.
The polyurethane prepolymer modified epoxy resin (component A) and the self-made curing agent (component B) are formulated to have high temperature resistance, good toughness and reactivity in a ratio of 10:1 to 1:1 (weight ratio). Large curing system.
The polyurethane prepolymer is a polyhydroxypolyurethane prepolymer which is prepared by reacting a hydroxyl terminated polysiloxane and a diisocyanate in a certain ratio under certain conditions to form an isocyanate group, and then using the polyurethane prepolymer to epoxy resin. Modified treatment.
The self-made curing agent is composed of a diamine, an imidazole compound, a silane coupling agent, an inorganic filler, and a catalyst.
The modified epoxy resin adhesive can be cured at room temperature, can be used for a long time at 200 ° C, or cured at -5 ° C for 150 ° C.
Bonding strength of 15-30MPa.
T-peel strength is 35-65N/cm, with excellent oil, water, acid, alkali and organic solvent resistance. It can bond wet surface, oil surface and metal, plastic, ceramic, hard rubber, wood and so on.
Second, what does acrylic do?
Main use: Used in resin manufacturing, synthetic rubber emulsion manufacturing and other fields.
Invasion pathway of methacrylic acid: inhalation, ingestion, percutaneous absorption.
application:
1. Important organic synthetic raw materials and synthetic resin monomers are ethylene monomers with very fast polymerization rate. Most of them are used to make acrylates such as methyl acrylate, ethyl ester, butyl ester and hydroxyethyl ester. Acrylic acid and acrylic acid. The ester can be homopolymerized and copolymerized, or copolymerized with monomers such as acrylonitrile, styrene, butadiene, vinyl chloride and maleic anhydride. The polymer is used in synthetic resins, adhesives, synthetic rubber, synthetic fibers, and high water absorption. Resin, pharmaceutical, leather, textile, chemical fiber, building materials, water treatment, oil extraction, coatings and other industrial sectors. Acrylic acid is one of the important raw materials for water-soluble polymers, and grafting copolymerization with starch can produce super absorbent;
2. Preparation of high polymer by homopolymerization or copolymerization for coatings, adhesives, solid resins, molding compounds, etc.
3. Preparation of acrylic resin, rubber synthesis, coating preparation, pharmaceutical industry;
4, warp yarn slurry
The warp yarn slurry prepared from raw materials such as acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate, etc., is desizing than the pulp on the polyvinyl alcohol to save starch.
5, adhesive
Copolymer latex such as acrylic acid, methyl acrylate, ethyl acrylate, 2-ethylhexyl acrylate or the like can be used as an adhesive for electrostatic flocking and planting, which has good fastness and good hand feeling.
6, water thickener
It is made of acrylic acid and ethyl acrylate copolymer to make high molecular weight powder. It can be used as thickener for oil field. It can increase 500t crude oil per ton of product, and it has better oil recovery effect for old wells.
(2) Adhesive, acrylic acid, methyl acrylate, ethyl acrylate, 2-ethylhexyl acrylate, etc.;
7, coated paper finishing agent
Using quaternary copolymer latex such as acrylic acid, butyl acrylate, 2-ethylhexyl acrylate or styrene as coated paper coating, the color retention is not yellow, the printing performance is good, the non-stick roller is better than the styrene-butadiene latex. Cool
8, polyacrylates
Acrylic acid can be used to produce various polyacrylate products (such as ammonium salts, sodium salts, potassium salts, aluminum salts, nickel salts, etc.). It can be used as a coagulant, water treatment agent, dispersant, thickener, food preservative Acid and alkali desiccant, softener and other polymer additives.
Third, related concepts
1, acrylic
Acrylic acid is an important organic synthetic raw material and a synthetic resin monomer, and is a vinyl monomer having a very fast polymerization rate. It is the simplest unsaturated carboxylic acid consisting of a vinyl group and a carboxyl group. Pure acrylic acid is a colorless, clear liquid with a characteristic pungent odor. It is miscible with water, alcohol, ether and chloroform and is prepared from propylene obtained from a refinery. Most are used to make acrylates such as methyl acrylate, ethyl ester, butyl ester, and hydroxyethyl ester. Acrylic acid and acrylate can be homopolymerized and copolymerized, and the polymer is used in industrial sectors such as synthetic resins, synthetic fibers, superabsorbent resins, building materials, and coatings. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a preliminary list of carcinogens, acrylic acid in the list of three types of carcinogens.
2, ethyl ester
Ethyl acetate structure Colorless transparent liquid. Fruity. volatile. Sensitive to the air. It can absorb water and water, which can slowly decompose and react acidicly. It is miscible with chloroform, ethanol, acetone and ether and soluble in water (10% ml/ml). It can dissolve certain metal salts (such as lithium chloride, cobalt chloride, zinc chloride, ferric chloride, etc.). The relative density is 0.902. Melting point -83 ° C. The boiling point of 77 ° C. The refractive index is 1.3719. Flash point 7.2 ° C (open cup). combustible. Vapor can form an explosive mixture with air. The median lethal dose (rat, oral) was 11.3 ml/kg. Irritating.
