Problems solved by technology

However, the above methods, whether it is high-temperature sintering or adding traditional coagulants such as cement and gypsum, either waste resources or pollute the environment, and the application prospects are not very ideal
It can be said that there is no green and environmentally friendly inorganic binder so far, which makes the produced straw products have excellent waterproof and fireproof properties.

Abstract

The invention discloses a waterproof fireproof reinforced binder used for a straw building block and a preparation method thereof. The binder comprises the following components: 53 to 57% of magnesium oxide, 30 to 34% of magnesium chloride, 0.05 to 0.1% of ammonium chloride, 0.02 to 0.1% of trisodium phosphate, 0.05 to 0.1% of sodium fluosilicate, 5 to 6% of 191 resin, 4 to 5% of a nanometer silicon waterproof agent and 1.5 to 2.5% of silica micro powder. A preparation method for the binder comprises the following steps: preparing an aqueous solution of magnesium chloride, sequentially adding magnesium oxide, ammonium chloride, trisodium phosphate, sodium fluosilicate and silica micro powder into the aqueous solution of magnesium chloride, carrying out stirring, then adding the 191 resin and the nanometer silicon waterproof agent and carrying out uniform stirring; The preparation method provided in the invention is simple to operate, and the binder is healthy and environment friendly, costs little, has a strong binding force and excellent waterproof and fireproof performances and enables the crop straw to be effectively utilized.

Description

technical field [0001] The invention relates to a binder and a preparation method thereof, in particular to a waterproof and fireproof reinforcing binder for straw blocks and a preparation method thereof. Background technique [0002] The reuse of waste crop stalks has always been a problem that people care about and needs to be solved urgently. Direct burning will damage the environment; making fertilizer or biogas, the utilization rate is not high. At present, the use of crushed straw to make bricks or boards as construction or decoration materials has become a hot spot in the application of turning waste into treasure. Application No. 200710107126.9 discloses the "Method for Making Straw Bricks" which requires heating and pressing straw powder, swim bladder glue and concrete. Application No. 200810156833.1 discloses "Plant Straw Waste Rubber Composite Floor Tiles" mainly using waste rubber, supplemented with straw powder and polyurethane adhesive, mixed evenly, heated a...
