Insulation coating crosslinking agent
Preparation of silicon propylene series coating. Will wetting dispersant, defoaming agent, preservative, thickener in water, stir to dissolve and add ultrafine rutile type titanium pigment, talc powder, after being fully wetting on grinding, when the particle size of up to 10 microns below, add FEHS - A, getting white stain resistant coatings, hereinafter referred to as FEHS - T.
Fehs-a latex infrared spectroscopy analysis. A small amount of fehs-a lotion, which is processed by film, washing, extraction, drying, etc., is used for the ft-ir infrared characterization after using KBr mixing.

At 1555 cm - 1 no ring siloxane ring body skeleton vibration peak, show the silica in V4 ring is open loop, in 1800 ~ 1860 cm - 1 no vinyl characteristic absorption peak, 3107 cm - 1 C - H without C = C key connected key stretching vibration peak, no double bonds in polymer that exists, that all the monomer has fully take part in the copolymerization reaction, silicon a crylic-acid copolymer formed.
FEHS emulsion of thermogravimetric analysis: FEHS - A initial decomposition temperature of 343 ℃, accounts for about 3.4% of the total, may be A small amount of water and oligomer, epitaxial starting temperature is 398 ℃, extension terminated temperature 468 ℃, weightlessness slope biggest point temperature 449 ℃; FEHS - B initial decomposition temperature of 350 ℃, accounts for about 2.7% of the total, epitaxial starting temperature is 410 ℃, the extension terminated temperature 479 ℃, weightlessness slope maximum point temperature 458 ℃. Thermal decomposition temperature is FEHS FEHS - B - A high average 11 ℃, under the condition of the same formula, FEHS - B method (second step) of silicone acrylic emulsion crosslinking degree is higher, better heat resistance.
Two steps: (1) into three bottles of deionized water, V4, MAA, emulsification, high speed stirring 0.5 h. Heat (80 + 2) ℃, with dilute hydrochloric acid to adjust pH value to 3.5 + / - 0.5, ring opening polymerization of 3 ~ 4 h, adjust pH value to 5 + / - 0.5, silicone emulsion, then add the remaining monomer and part of the initiator, high-speed stirring again, 0.5 h emulsification, get hybrid emulsion. (2) take another with a mixer, thermometer, condenser pipe and dropping funnel four bottles, dropping funnel add hybrid emulsion, adding deionized water bottle and part of K2S2O8 - NaHSO3, heat (80 + 2) ℃, using hydrochloric acid pH adjustment system to 5 + / - 0.5, slowly add hybrid emulsion, with 3 ~ 4 h drops out, keep 2 h, add remaining K2S2O8 - NaHSO3, continue to cure 2 h, cooled to 50 ℃, ammonia, is used to adjust pH value to 7.5 + / - 0.1, beaten, with 100 mesh screen sieve, get the self crosslinking of the generic blue opalescence soap-free emulsion, silicon a crylic-acid FEHS - B for short.
