Abstract
The invention discloses a kind of composite expanded perlite sheet material and preparation method thereof, comprise the following steps: described expanded perlite, adhesive, white glue with vinyl, refractory ceramics powder, water are added stirrer for mixing 10min by (1)；(2) said mixture is loaded in molding jig compressing；(3) model of molding is put in stove, at 300 350 DEG C, fire 12h.A kind of composite expanded perlite sheet material that the present invention provides and preparation method thereof, select perforate expanded perlite, organo-mineral complexing adhesive, refractory ceramics powder is raw material so that described composite expanded perlite sheet material has that intensity is big, toughness big, strong shock resistance, the most hygroscopic good characteristic.
Description
Technical field
The present invention relates to a kind of expanded pearlite rock beam field, be specifically related to a kind of composite expanded perlite sheet material and preparation thereof
Method.
Background technology
In recent years, along with the development of China's building energy conservation cause, the heat preserving and insulating material of various inner wall of building exterior walls met the tendency
And give birth to, for construction material, while realizing insulation, it is also desirable to have the characteristic such as fire prevention, moisture resistance, length in service life.Swollen
Swollen perlite material has the characteristic do not fired as a kind of inorganic heat insulation material, simultaneously as light weight, aging resistance, corrosion-resistant, nothing
Tasteless, the cheap feature of poison is favored in insulation material research boom.But the usual intensity of expanded perlite product
Low, impact resistance is strong, and transport and use to material bring great inconvenience, additionally, expanded perlite product is as nothing
Machine porous material is hygroscopic, and after water suction, physical and chemical performance all receives certain impact.
In order to improve the impact resistance of normal expanded perlite sheet material, in the market expanded perlite sheet material be all with
Waterglass be binding agent to prepare expanded perlite sheet material, but sodium silicate 220 DEG C begin to expand flowing, prepared is swollen
Swollen perlite sheet material, under big fire calcination, can distort, and sodium silicate is as inorganic binder in obvious contraction distortion, and cohesive force is not
By force, expanded perlite sheet material is caused to be highly brittle.In order to improve the performance of expanded perlite sheet material, farthest play it excellent
Gesture, it would be desirable to select suitable binding agent and raw material to prepare the NEW TYPE OF COMPOSITE expanded perlite sheet material accorded with the demands of the market.
Summary of the invention
The technical problem to be solved is to provide a kind of composite expanded perlite sheet material and preparation method thereof, tool
Have that intensity is big, toughness big, strong shock resistance, the most hygroscopic good characteristic.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of composite expanded perlite sheet material, wherein, described raw material components comprises as follows by weight percentage: expanded perlite
39-43%, adhesive 23-27%, white glue with vinyl 6-10%, refractory ceramics powder 8-12%, water 10-20%.
Above-mentioned composite expanded perlite sheet material, wherein, described expanded perlite selects perforate expanded perlite.
Above-mentioned composite expanded perlite sheet material, wherein, described adhesive is by waterglass 88-92%, boric acid 2-4%, phenylpropyl alcohol breast
Liquid 5-10% mixes.
The present invention solves that above-mentioned technical problem additionally provides a kind of composite expanded perlite preparation of plates method, including
Following steps:
(1) described expanded perlite, adhesive, white glue with vinyl, refractory ceramics powder, water are added stirrer for mixing 10min；
(2) said mixture is loaded in molding jig compressing；
(3) model of molding is put in stove, at 300-350 DEG C, fire 12h.
The present invention has the advantages that the present invention selects perforate expanded perlite compared to existing technology, adhesive and
White glue with vinyl penetrates in expanded perlite more easily by surface opening, so that composite expanded perlite sheet material impact resistance
Can be preferably；Selecting organo-mineral complexing adhesive by Organic substance bridging, system network can be complicated, polymer is formed
The rigid chain network that formed of flexible chain network and inorganic matter run through mutually, add composite expanded perlite sheet material intensity and
Toughness, also makes composite expanded perlite sheet material water absorbing capacity die down simultaneously；Refractory ceramics powder can be formed with sodium silicate
The contiguous network of effect, improves the fire protecting performance of composite expanded perlite sheet material.
