Description

The high-strength panel that a kind of fire resistance is good
Technical field
The present invention relates to decoration material field, fireproof door plate such as particularly a kind of very-high performance family expenses, office or desktop, cabinet panel.
Background technology
Prior art and situation are described:
The door-plate of the preparation building at present both at home and abroad especially material of employing such as fireproof door plate, desktop panel mainly comprises steel, wooden, glass material etc.General steel material high temperatures property is poor, and thermal conductivity is high, and heat-proof quality is relatively poor, and cost is high.There are deficiencies such as fire resistance is poor, yielding, corrosion resistance difference in common wooden panels; Glass door panel has satisfied the demand of aesthetic property, but fragility is big, and shock resistance is poor, and intensity is lower.
The present invention is directed to problem and limitation that building decorative plates exists; Prepare dalle---very-high performance cement based composite sheets such as a kind of very-high performance, NEW TYPE OF COMPOSITE fireproof door plate, cabinet and desktop panel, can enlarge the raw-material source of building decorative plates on the one hand; Reduce demand on the other hand, reduced cost timber, steel and plastics; The more important thing is that this sheet material has fabulous fire resistance.
Main method is in the cement inorganic coagulation material, to mix an amount of high reactivity, micron-class superfine breeze (hereinafter to be referred as the micron breeze), mineral admixture composite powder, the inert aggregate that is not more than 5mm, organic fibre, and mixs such as warp and water, sclerosis form.Used micron-class superfine breeze activity index is 1.5～2 times of common adulterant activity index, and specific surface area is 1000m 2/ kg～3000m 2/ kg is 3～6 times of common mineral admixture.Such micron order breeze is incorporated in the cement system, makes the structure of hydrated product fine and close more, and folding strength reaches 18～30MPa, and ultimate compression strength can reach 80～120MPa.The sheet material resistivity against fire reaches category-A " heat-insulating fireproof door " and requires (GB 12955-2008).Used mineral admixture composite powder is the composite powder through binary such as the silicon ash of suitable proportioning, common breeze or polynary adulterant, and the adding of composite powder further reduces the product porosity, the surface smoothness and the weather resistance of raising sheet material.Under the situation that does not influence timber intensity and degree of compactness, the adding that is not more than the inert aggregate of 5mm further reduces the preparation of plates cost.
The composite sheet surface of preparation is evenly smooth, sturdy and durable; Can satisfy the profile pattern requirement through compression moulding technology; Require to carry out surface treatment according to aesthetic property simultaneously; Good stability, intensity is high, and non-deformability is good.
The reason that the defective of prior art and defective produce:
1, steel material high temperatures property is poor, and thermal conductivity is high, thereby heat-proof quality is relatively poor, and cost is high.
2, the application of wood materials has improved the demand to natural resources greatly, and the corrosion resistance of normal wood prepared material is relatively poor, and water ratio is higher, and is yielding, intensity is lower, and particularly fire resistance is poor.
3, glass board material intensity is low, and fragility is big, is prone to go to pot.
4, the preparation of plastic plate should not be used for the demanding panel preparations of fire performance such as fire door, and the application of such organic polymer material is unfavorable for HUMAN HEALTH.
In a word, existing all kinds of dalles can not well satisfy firm, safe, the suitable and attractive in appearance demand of people to dalle because production cost is higher, and range of application is limited.
Summary of the invention
Technical problem: the purpose of this invention is to provide the good high-strength panel of a kind of fire resistance, the stability of this sheet material is high, shock resistance is good, fp cement based door-plate or furniture panel.This sheet material resistivity against fire reaches category-A " heat-insulating fireproof door " and requires (GB 12955-2008).Be applicable to continuous industry production, mechanization degree is high, and with short production cycle, sheet material is firm, durable.Be used for replacing door-plate and furniture panels such as wooden, plastics, can be used as that fire resistance is good, intensity high building door-plate and other dalles.
Technical scheme: the present invention uses cement as inorganic coagulation material; Replace a certain amount of cement with high reactivity, micron-class superfine breeze; Mix an amount of binary or polynary composite powder (hereinafter to be referred as composite powder) through the mineral admixture of optimizing proportioning, and add an amount of particle diameter at 5mm with interior inert aggregate, and volume(tric)fraction is about 1%～3% organic fibre; Preparation process control wc is between 0.15～0.30, and all raw material all is materials harmless to human non-toxic.Can obtain that good stability, shock resistance are high, after the drying treatment water ratio far below the door-plate or the desktop panel of 12% (GB 12955-2008).Plate surface is smooth, bright and clean, and wear resistance is good, safety is high; After actuation test repeatedly, such sheet material non-loosening, come off, phenomenons such as gross distortion, keying jam, open and close good stability.
