With the concrete parting agent that rosin is made, the weight part of its constitutive material is: modified rosin 35, sweet oil 22, triethylene diamine 0.7, calcium zinc stabilizer 9, alkenyl succinic acid ester 2.5, pentanoic 1.8, stearin 1.5, stearic acid 4.5, Quilonum Retard 0.2, Sodium Silicofluoride 0.5 and deionized water 180.

The preparation method of the concrete parting agent made with rosin, comprises following content:

(1) preparation of modified rosin: first by rosin heating to 50-60 DEG C; Then the 3.5-4.0% ferrous sulfate of rosin quality, 8-10% carbon fiber, 10-15% bamboo fibers is added wherein; Be uniformly mixed and place 2-3 hour, and then add the potassium humate powder of rosin 4-5%, be warming up to uniform stirring 1-2 hour under the condition of 80-90 DEG C, naturally cool to room temperature, regulator solution pH value is to 2-3; Again with deionized water in mass ratio 1:5 mix, stir 30-40 minute, centrifugation obtains filtrate;

(2) take each raw material by the weight part of constitutive material, the modified rosin of step (1) is put into reactor, is heated to 100-120 DEG C, in heat-processed, spills minor amount of water; Then sweet oil, triethylene diamine and calcium zinc stabilizer is added; Continue heat and stir 40-50 minute, temperature controls in the scope of 140 DEG C-150 DEG C; Finally add other residue constitutive material, continue to be stirred to moisture and evaporate completely, to obtain final product.

Beneficial effect of the present invention:

The present invention has good stripping result; by the modification to rosin; make demoulding slip good; realize it to the fast demoulding between concrete and mould; the smooth zero defect of concrete surface after the demoulding, the sticky amount of mould concrete is few, to template non-corroding; the present invention's green, environmental protection, economy, be applicable to applying widely.
