Abstract
Air-entrained concrete building block of fire protection flame retarding and preparation method thereof.An air-entrained concrete building block for fire protection flame retarding, is made up of the raw material of following weight part: cement 15-20, unslaked lime 10-15, gypsum 8-12, loess 20-25, aluminium powder 0.2-0.3, ether of cellulose 1-2, cornstalk powder 20-25, hot pepper vine powder 10-15, oil foot 8-10, aluminium hydroxide 3-5, tschermigite 3-5, ammonium persulphate 2-3, Starso 10-15.The air-entrained concrete building block that the present invention produces, wherein adopt oil foot composition, through initiator modification, add the hydrophobicity of building block, greatly improve its infiltration ability, building block of the present invention uses at community exterior wall, last more than 3 years, do not find wall leakage phenomenon, and adopt traditional air-entrained concrete building block, annual Jun You resident family appearance infiltration in spring.Adopt aluminium hydroxide and tschermigite in the present invention, there is good flame retardant resistance, the risk of catching fire can be greatly reduced.
Description
Technical field
The invention belongs to a kind of building material technique, specifically a kind of concrete segment and preparation method thereof.
Background technology
Novel wall material gas concrete as a kind of less energy-consumption, the New Building Materials of environment-friendly type, belong to the material of construction that country promotes, but because ordinary air-entrained concrete is made up of cement, flyash, unslaked lime, gypsum etc., there is the problems such as drying shrinkage value is large, intensity is low, infiltration, not corrosion-resistant, thermal insulation is not good, material source is single, therefore, be badly in need of air-entrained concrete building block technology is studied further, make the requirement further meeting market.
Summary of the invention
Air-entrained concrete building block that the object of this invention is to provide fire protection flame retarding and preparation method thereof, to solve the fire protection flame retarding problem that current air-entrained concrete building block exists.
Technical scheme of the present invention is as follows:
An air-entrained concrete building block for fire protection flame retarding, is characterized in that being made up of the raw material of following weight part: cement 15-20, unslaked lime 10-15, gypsum 8-12, loess 20-25, aluminium powder 0.2-0.3, ether of cellulose 1-2, cornstalk powder 20-25, hot pepper vine powder 10-15, oil foot 8-10, aluminium hydroxide 3-5, tschermigite 3-5, ammonium persulphate 2-3, Starso 10-15.
The preparation method of the air-entrained concrete building block of described fire protection flame retarding, is characterized in that comprising the following steps:
(1), Starso is added suitable quantity of water, be heated to 60-70 DEG C, stir, add oil foot, aluminium hydroxide, stir 15-25 minute, add cornstalk powder, hot pepper vine powder again, stir 30-45 minute, then add ether of cellulose, loess, stir 30-45 minute, then add ammonium persulphate, stir after 30-45 minute, stir into mud;
(2), by cement, tschermigite add 90-100 DEG C of hot water mixing 15-25 minute, then, add other materials such as the mud of step (1) gained and unslaked lime, aluminium powder, gypsum, stir 10-15 minute, obtain the slurry that water content is 30-35%;
(3), by slurry pour into a mould, to send in 40-60 DEG C of drying room after precuring 1.5-2.5 hour, cut into building block base, on the outer wall of building block base, be coated with last layer dimethyl silicone oil; ;
(4), by building block send into steam press maintenance in still, vapor pressure 1-1.3Mpa, the steam-cured time 6-8.0h of constant voltage obtains finished product.
The air-entrained concrete building block that the present invention produces, wherein adopt oil foot composition, through initiator modification, add the hydrophobicity of building block, greatly improve its infiltration ability, building block of the present invention uses at community exterior wall, last more than 3 years, do not find wall leakage phenomenon, and adopt traditional air-entrained concrete building block, annual Jun You resident family appearance infiltration in spring.Adopt aluminium hydroxide and tschermigite in the present invention, there is good flame retardant resistance, the risk of catching fire can be greatly reduced.
The air-entrained concrete building block that the present invention produces has that ultimate compression strength is high, light weight, sound insulation, heat insulation, good heat preservation performance, anti-freezing property and the advantage such as contraction is little thereof, solves the defect that traditional air-entrained concrete building block intensity is low, easy to crack.
