1. Product Introduction
(1) Acrylic acid is the simplest unsaturated carboxylic acid.
Its molecular structure is composed of one vinyl group and one
carboxyl group. Pure acrylic acid is a colorless clear liquid with
characteristic pungent smell. Density 1.***1. Melting point: *4
℃. Boiling point **0.9 ℃. Strong acidity. Corrosive. Soluble in
water, ethanol and ether. Chemically active. Easy to polymerize
into transparent white powder. Propionic acid is formed during
reduction. *-chloropropionic acid is formed when it is added with
hydrochloric acid. It is used for preparing acrylic resin and other
organic synthesis. It is prepared by oxidation of acrolein or
hydrolysis of acrylonitrile, synthesis of acetylene, carbon
monoxide and water, or pressurized oxidation of ethylene and carbon
monoxide.
(2) Acrylic acid can undergo the characteristic reaction of
carboxylic acid, and the corresponding esters can also be obtained
by reacting with alcohol. The most common acrylates include methyl
acrylate, butyl acrylate, ethyl acrylate and *-ethylhexyl
acrylate.
(3) After acrylic acid and its esters are mixed with itself or
other monomers, polymerization will occur to form homopolymers or
copolymers. Generally, monomers that can be copolymerized with
acrylic acid include amides, acrylonitrile, vinyl containing
monomers, styrene and butadiene. These polymers can be used to
produce all kinds of plastics, coatings, adhesives, elastomers,
floor polishes and coatings.
2. Usage
Acrylic acid and its series products, mainly its esters, have
developed rapidly in recent years. For example, ethylene,
propylene, vinyl chloride and acrylonitrile have developed into
important raw materials for polymer chemical industry. Acrylic acid
and its esters as monomers of polymer compounds, the world's total
output has exceeded 1 million T, and the output of polymer and
copolymer (mainly emulsion type resin) produced by it is nearly 5
million T. These resins are widely used in coatings, plastics,
textiles, leather, papermaking, building materials, packaging
materials and many other departments. Acrylic acid and its esters
can be used for organic synthesis and polymer synthesis, and most
of them are used for the latter, and are more copolymerized with
other monomers, such as vinyl acetate, styrene and methyl
methacrylate, to prepare synthetic tree esters with various
properties, functional polymer materials and various
additives.
3. Application
(1) Warp sizing
Warp sizing agent prepared from acrylic acid, methyl acrylate,
ethyl acrylate, acrylonitrile, ammonium polyacrylate and other raw
materials can desize and save starch than polyvinyl alcohol sizing
agent.
(2) Adhesive
The copolymer latex of acrylic acid, methyl acrylate, ethyl
acrylate and *-ethylhexyl acrylate can be used as the adhesive for
electrostatic flocking and wool planting. It has good firmness and
hand feel.
(3) Water thickener
A high molecular weight powder was prepared from the copolymer
of acrylic acid and ethyl acrylate. It can be used as thickener in
oil field. It can increase **0t crude oil per ton of product, and
has good oil recovery effect for old wells.
(4) Coated paper finishing agent
Using acrylic acid, butyl acrylate, *-ethylhexyl acrylate,
styrene and other quaternary copolymer latex as coated paper
coating has the advantages of color retention, no yellowing, good
printing performance, no roll adhesion, better than styrene
butadiene latex, and can save dry pigment
(5) Polyacrylates use acrylic acid to produce various
polyacrylate products (such as ammonium salt, sodium salt,
potassium salt, aluminum salt, nickel salt, etc.). Used as
coagulant, water treatment agent, dispersant, thickener, food
preservative, acid-base resistant desiccant, softener and other
polymer additives.
