Epoxy resin and epoxy coating crosslinking agent,Developing very rapidly, China has become a huge market for epoxy product. The application of epoxy resin and epoxy crosslinking agent products, is a comprehensive, including industry, agriculture, food and so on each domain. The application of epoxy resin and epoxy crosslinking agent can also be divided into the following several parts.
: (1) the car industry is one of the four pillar industries in China, and the car demand is bigger and bigger, and the electrophoresis paint of form a complete set of epoxy resin and epoxy crosslinking agent, maintenance needs to be painted with epoxy.
(2) the electric power industry: China's power industry scale, and is in rapid development phase, the epoxy is expanding by 60% year on year increase. The field from the power generation, power transmission and transformation to the electricity needs to be epoxy products, such as insulation materials, dry type transformer, switch, transformer, water conservancy and hydropower project. Cut in the operation of the hydropower station construction and epoxy resin and epoxy crosslinking agent role irreplaceable.
(3) vessels and Marine industry: China is a maritime power, shipbuilding, the 21st century is the century of ocean. Ships, port facilities, construction, offshore drilling platforms, pipelines, mariculture facilities, etc., requires a lot of epoxy coating (anticorrosive, Marine pollution prevention).
(4) the electronics industry, one of the four pillar industries in China developing rapidly. Epoxy resin and epoxy crosslinking agent role in the electronic industry is very important, epoxy resin adhesive glue agent industry has become a very large industry chain.
(5) the container industry: China's container industry developing rapidly, has become the world's major container production base (10% ~ 15% of the world total). Container paint, container paint special crosslinking agent all drives the development of epoxy resin and epoxy crosslinking agent industry.
(6) food cans industry: with the improvement of living standards, the rapid growth of canned food, food storage container manufacturing, canned epoxy resin coating needs more and more.
(7) in terms of the varieties of epoxy resin, epoxy powder coating, waterborne epoxy paint the sky's the limit. This is the mainstream in the development of epoxy coating. China is the world's fourth largest producer of powder coatings, is Asia's largest producer of powder coatings. China has the powder coatings and water-borne coatings determine priorities for the future development of varieties, and water-borne epoxy coatings and played important roles in the coating industry.
Industry as a control index of the resin is as follows:
(1) the epoxy value. Epoxy value is to identify the primary indicator of the properties of epoxy resin, epoxy resin industry model is different according to the epoxy value to distinguish. Epoxy value refers to the per 100 g resin containing epoxy group in the number of amount of substance. The reciprocal of epoxy value multiplied by 100 call it epoxy equivalent. Epoxy equivalent meaning is: epoxy resin containing epoxy groups 1 mol grams.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
(2) inorganic chlorine content. With amine resin in the chloride ion on crosslinking agent complexation and affect resin crosslinking, also influence of crosslinked resin performance, therefore the chlorine content is an important indicator of epoxy resin.
(3) organic chlorine content. The organochlorine content in resin has marked the molecules in the closed-loop response that part of the chlorohydrin group content, its content should be reduced as much as possible, otherwise will affect performance of the resin crosslinking and crosslinking.
(4) the volatile.
(5) the viscosity and softening point.
Waterborne epoxy resin system usually adopts the crosslinking agent emulsification method for preparation of waterborne epoxy resin emulsion. The epoxy resin in this type of system is general not emulsified beforehand, while the waterborne epoxy crosslinking agent before use hybrid emulsion, so this kind of crosslinking agent must be as crosslinking agent and emulsifier.
