Description
Technical field
The present invention relates to a kind of decoration panel, particularly antimagnetic decoration panel.
Background technology
Along with the fast development of science and technology and electronic industry, electric, electronics is widely used in all respects of productive life.Meanwhile, produce a large amount of electromagnetic radiation and interference in electronics, electric system equipment work process.Electromagenetic wave radiation pollutes the 4th large public hazards that have been acknowledged as after topsoil, water pollution, noise pollution.The interference and the leakage that cause for solving electromagenetic wave radiation mainly adopt electromagnetic shielding material to shield.Traditional shielding means are mainly that applied metal and mixture thereof are as shielding material, although these materials have good effectiveness of shielding, the shortcoming such as exist that physics finite elastic, quality are large, difficult processing, price are high, perishable, be difficult to regulate effectiveness of shielding and regeneration potential is poor.The antimagnetic poor-performing of decoration panel, be necessary to how making antimagnetic decoration panel to conduct a research at present.
The electromagnetic wavelength of the particle diameter ratio of nano titanium oxide is much smaller, thereby stronger to the electromagnetic transmitance of this wave band with its matrix material of making, and it obviously reduces electromagnetic reflection, and absorbing property is better.Simultaneously due to nano titanium oxide.The surface atom number is a lot, active strong, and under electromagnetic radiation, atom and electron motion aggravation impel magnetization, polarization and conduction motion, make electromagnetic energy be converted into heat energy, thereby have improved electromagnetic receptivity.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of antimagnetic decoration panel of good physical performance.
For this reason, the raw material weight proportioning of decoration panel provided by the invention is: 30 parts～32 parts, diatomite, 13 parts～15 parts of carbide slags, 8 parts～10 parts of cement, 8 parts～10 parts, glass fibre, 0.5 part～1 part of silane coupling agent, 11 parts～13 parts of manganese powders, 7 parts～9 parts of nano titanium oxides, 15 parts～17 parts, water.
The diatomite fineness is more than 200 orders, and cement adopts 32.5 grades of ordinary Portland cements, and in carbide slag, effectively the calcium amount is more than 70%, and carbide slag adopts the waste residue of resin processing plant's discharging, and the manganese powder fineness is 50 orders, and glass fibre length is 5～7mm.
The present invention forms the conductive mesh skeleton by being in contact with one another between conductive filler material manganese powder particle, and its electricity is led the summation that effect is the various carrier transport quantities of electric charge.Table 1 is that the manganese powder volume is on the impact of screen effect, show the increase gradually along with manganese powder content in table, because the bridge joint effect of manganese powder increases being coupled to each other a little between the manganese powder particle, the filler particles contact probability increases, the more complete densification of three-dimensional conductive network skeleton of formation.Under electromagnetic effect, the concentration of current carrier increases, and the migrating channels of current carrier increases; Therefore, the specific conductivity of material can increase naturally, and correspondingly, the resistivity of material will reduce gradually.When the manganese powder volume is 11～13 parts, the complete densification that becomes of the three-dimensional conductive network skeleton of formation, the migrating channels of current carrier reaches maximum value; Therefore, the screen of material effect reaches maximum.Further increase the content of manganese powder, can reduce mobility and the dispersive ability of slurry, reduce the quality of material; Therefore, the screen of material effect descends on the contrary to some extent.
The impact of table 1 manganese powder volume on the screen effect
Table 2 is the impact that the nano titanium oxide volume is imitated screen, compares with the electromagnetic shielding effectiveness of the material that does not contain nano titanium oxide, and effectiveness of shielding has improved 4～9.6dB.This shows that adding nano titanium oxide is improved significantly the bulk shielding effect of material.This is due to the bridge joint effect that there is no nano titanium oxide, is a contact between the manganese powder particle, and the contact probability between particle is less, and the three-dimensional conductive network skeleton of formation is more loose, but hertzian wave permeable material layer; Therefore, less to electromagnetic reflection and absorption loss, correspondingly, the effectiveness of shielding of material is relatively poor.Along with increase frequency, effectiveness of shielding strengthens the effect of depending on of electroconductibility; Therefore, at high band, the electromagnetic shielding effectiveness of material that does not contain nano titanium oxide is relatively poor, thereby causes the bulk shielding effect of material undesirable.
