Abstract

A small expended and vitrified ball sound absorbing baffle consists of the following components according to weight percentage, and is characterized in that: small expended and vitrified balls occupy 55 to 64 percent, soluble glass Na2SiO3 occupies 31 to 41 percent, sodium fluosilicate occupies 3 to 5 percent and water-repellent agent occupies 0.1 to 0.5 percent. The production method comprises the following steps of: color selecting, expending and vitrifying, filtering, mixing, molding, drying and packing. The small expended and vitrified ball sound absorbing baffle has the advantages of light weight, thermal insulation and fire prevention, high-temperature and low-temperature resistance, anti-ageing property, low water absorbing capacity and high sound absorption capacity owing that the baffle is molded mainly by agglomeration and the surface has a large quantity of through millipores without spray finishing on the surface.

Description

Expansion vitrification micro-sphere heat insulation formwork and production method thereof
Technical field
The present invention relates to a kind of novel architecture plate and production method thereof, especially a kind of expansion vitrification micro-sphere heat insulation formwork and production method thereof about having the sound-insulating performance.
Technical background
The at present existing heat preservation and soundproof that is used for wall construction is a lot of with plate, these building slabs mostly adopt organic materials to be made, acoustic board mainly contains the cotton acoustic board in ore deposit (rock, glass), steel fiber acoustic board and perlite acoustic board etc., though above material has certain sound absorption, performance such as heat insulation, but exist sound absorption efficiency poor, pollute big, weight is big, water-absorbent is big, big, the defectives such as cost is high, thermal and insulating performance difference of volumetric shrinkage in the easy moisture absorption and deformation, use.
Summary of the invention
At above deficiency, the object of the present invention is to provide a kind of is the acoustic board and the production method thereof of main material with expanded and vitrified small ball.
Technical scheme of the present invention realizes in the following manner: expansion vitrification micro-sphere heat insulation formwork is represented with weight percent by following component component:
Expanded and vitrified small ball is 55-64%, water glass Na 2SiO 3For 31-41%, Sodium Silicofluoride are 3-5%, hydrophober 0.1-0.5%.
Above-mentioned hydrophober is organosilicon micro emulsion concentrated solution.
Production method of the present invention comprises following operation successively:
(1), the pitchstone ore is carried out look choosing, select the processing together of same color and luster to use in order to expansion vitrification;
(2), the pitchstone ore in sand form of same color and luster is carried out expansion vitrification, make the expanded and vitrified small ball color and luster identical;
(3), expanded and vitrified small ball is screened, remove other dregs, use in order to making sheet;
(4), Sodium Silicofluoride is added the dilution of certain water gaging put into concentration then and stir at 38-42% water glass, and add hydrophober and stir evenly;
(5), the expanded and vitrified small ball that the material after will stirring and screening are good stirs evenly the formation mixture;
(6), taking-up was placed on moulding on the iron pallet after the mould that pressing machine is put in above mixture metering was forced into 20-25Mpa;
(7), the one-tenth parison on the iron pallet is placed on the tunnel furnace inner drying, make whole process drying temperature be para-curve by 60 ℃-400 ℃-60 ℃ by the venting hole of regulating the tunnel furnace both sides and change, the time is 37 hours.
(8), inspection matter packing.
The expansion vitrification micro-sphere heat insulation formwork that adopts the present invention to produce has light weight, heat-insulating, fire-preventing, high-low temperature resistant, anti-aging, good characteristic such as water-intake rate is little.It has overcome many defectives of other acoustic board, and mainly by sinter molding, the surface does not spray possesses a large amount of perforation surface micropores, strengthens sound absorbing capabilities.
