Abstract
The invention discloses a glass magnesium plate composite modifier which is characterized by comprising the following components in percentage by weight: 5-10% of phosphate, 16-20% of talcum powder, 55-65% of fly ash and the balance of lignosulfonate. The modifier disclosed by the invention can effectively improve the phenomena of halogenide reforming, scumming, poor water resistance, deformation and the like of the glass magnesium plate.
Description
Technical field
The present invention is specifically related to a kind of glass fibre and magnesium cement board composite modifier and application thereof.
Background technology
Glass fibre and magnesium cement board, also known as fire-resistant composite panel (also claiming magnesium oxide plate), adopts magnesium oxychloride material to prepare.Magnesium oxychloride material is a kind of air setting material (room temperature more than 10 DEG C; can harden and solidify) have unburned, non-evaporating foster power saving function, in order to alternative clay materials for wall; having the function value of protection of the environment, is the strategic material meeting current energy-saving and emission-reduction Sustainable development.And can trade waste be fully utilized in the composition material of magnesium oxychloride material goods, and such as: flyash, slag, slag, silicon ash, glass cullet, building waste, wheat straw, straw, rice husk.And the wagnerite of China, account for global about 30% at the reserves of China.Magnesium chloride is throughout coastal each salt mine, well salt and lake salt.Abundant magnesium resource is the richness basis of Chinese development magnesium oxychloride material and goods.
But magnesium oxychloride material also exists following defect: return halogen: dosage is improper or maintenance is improper, produce superfluous and remaining magnesium chloride, magnesium chloride is a kind of moisture adsorbent, is to cause the key returning halogen; Scum: the sodium-chlor in magnesium chloride impurities, Repone K is high, and the loss on ignition in magnesium oxide is large; Waterproof: the not fine and close and phase transformation of magnesium oxychloride product structure causes water resistance poor; Distortion: because of thickness and density variation and structure asymmetric, cause hydrofuge not at the uniform velocity, inconsistently cause shrinkage strain.
Summary of the invention
The object of the invention is to solve the defect existed in prior art, providing a kind of and effectively can improve the properties-correcting agent that glass fibre and magnesium cement board returns the defects such as halogen, scum, water resistance difference and distortion.
In order to achieve the above object, the invention provides a kind of glass fibre and magnesium cement board composite modifier, it is characterized in that, comprise the component of following weight percent: phosphoric acid salt 5%-10%, talcum powder 16%-20%, flyash 55%-65%, surplus is sulfonated lignin.
Wherein, silicon-dioxide 25%-30% is contained in flyash.
Phosphoric acid salt adopts SODIUM PHOSPHATE, MONOBASIC; Sulfonated lignin adopt sodium lignosulfonate.
The preferred ingredient proportioning of glass fibre and magnesium cement board composite modifier of the present invention is: SODIUM PHOSPHATE, MONOBASIC 6%, talcum powder 20%, flyash 59%, and surplus is sodium lignosulfonate; Wherein, silicon-dioxide 30% is contained in flyash.
Present invention also offers the application of above-mentioned glass fibre and magnesium cement board composite modifier on glass fibre and magnesium cement board, carrying out the preparation of glass fibre and magnesium cement board by adding glass fibre and magnesium cement board composite modifier of the present invention in glass fibre and magnesium cement board raw material; Wherein in glass fibre and magnesium cement board raw material, add glass fibre and magnesium cement board composite modifier 2 ‰-4 ‰, preferred add-on is 2.7 ‰-3 ‰, and optimal addn is 2.7 ‰.
The present invention has the following advantages compared to existing technology: the present invention adopts phosphoric acid salt to improve secondary waterproof distortion; Talcum powder is utilized suitably to alleviate density; Utilize silicon-dioxide to improve chlorine magnesium stability, utilize ligninsulfonate to increase edges of boards degree of mobilization, preventing board face peripheric blister is too much simultaneously.
