preparation example Construction

[0035] The preparation method of the modified wheat straw is as follows: dry the wheat straw, pulverize it with a pulverizer, take the wheat straw powder passed through a 120 mesh sieve, add a sodium hydroxide solution 15-20 times the mass of the wheat straw powder, Stand and soak for 18-20 hours, filter with suction, discard the filtrate, wash the remaining solid with water to neutrality, and dry at 50-60°C. The mass concentration of the sodium hydroxide solution is 6-10wt%, and the obtained To process the wheat straw powder, add N,N-dimethylformamide DMF 40-45 times the mass of the pretreated wheat straw powder, stir for 30-40 minutes, continue stirring and add maleic anhydride MA, the maleic anhydride MA Acid anhydride MA: The mass ratio of pretreated wheat straw powder is 0.75-0.8:1, and then the temperature is raised to 100-110°C for reaction. The reaction process is kept stirring. After 2-6 hours of reaction, the product is cooled to room temperature, and the filtrate is ...

Abstract

A self-heat preservation building block, comprising the following raw materials: 45-52 parts by weight of puddle from the Yellow River, 37-41 parts by weight of muddy limestone from Mount Ni, 1.5-3.8 parts by weight of polyphenylene sulfide powder, 2.1-2.3 parts by weight of glass micro-beads, 1.0-1.3 parts by weight of a third mixture, 30-45 parts by weight of a first mixed solution, a first additive accounting for 2 wt% to 3 wt% of the weight of the first mixed solution, and a second additive accounting for 0.025 wt% to 0.035 wt% of the mass of the first mixed solution. The first mixed solution comprises acrylic acid, polyvinyl alcohol, modified wheat straw, and water.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a self-insulating block. Background technique [0002] The advantage of external wall self-insulation and thermal insulation blocks is that it is accompanied by the theme construction, the overall construction timeliness of the project is high, the masonry is convenient, and the cumbersome process of secondary thermal insulation is eliminated, the construction cost is reduced, and the price is relatively low. New wall materials sintered with river and lake silt and composite blocks produced from fly ash, slag, coal gangue and other materials have been fully utilized in our country. Standard bricks are used for load-bearing walls and perforated bricks are used for frame structure infill walls. The existing problem is that the wall cannot meet the energy-saving and thermal insulation effect of 50% of public buildings and 65% of residential buildings stipulated by the state. Ins...
