Described a kind of anticorrosion anti-erosion thermal insulation mortar is characterized in that:

The preparation method is:

(1) the stalk ashes being put into concentration is that the acetic acid solution of 5-8% soaked 8-10 hour, take out, deionized water wash, oven dry adds the polyoxyethylene nonylphenol ether of the silane coupling agent KH530, the 0.1-0.2% that are equivalent to its weight 0.8-1.5%, the antioxidant 2246 of 1-2%, the tetraethoxy of 1-2%, and appropriate water, under 800-1000rpm after high-speed stirring 10-15 minute, take out, oven dry namely gets the modified straw ashes standby;

(2) the special fourth of epoxy soybean oil, sugared calcium, river sand, organosilicon, methacrylic acid, aluminum stearate, barium stearate, phenylformic acid mixing by weight, add again and be equivalent to above-mentioned raw materials gross weight 2-3 water doubly, stirred 10-20 minute under 30-35 ℃, get anticorrosion annex solution standby;

(3) with ordinary Portland cement, swelling perlite powder, modified straw ashes mixing, then add anticorrosion annex solution, stir; Add again surplus stock, stirred 20-30 minute under 25-35 ℃, and get final product.

Beneficial effect of the present invention is: the present invention has very strong anticorrosion corrosion resistance, has simultaneously the diminishing function, can extend its work-ing life.Sugar calcium is a kind of good water reducer, greatly improves water-reducing rate.
