2h
2o), calcium carbonate, how rice photocatalyst or colorant powder.In this, in inorganic silicate frie retardant coating, adding zinc can further provide substrate antirust function; In inorganic silicate frie retardant coating, adding magnesium silicate hydrate or calcium carbonate can make inorganic silicate frie retardant coating of the present invention become the interior paint of indoor decoration wall; In inorganic silicate frie retardant coating, add the function how rice photocatalyst can further provide sterilization, deodorizing.
Preferably, in the time that inorganic solvent is water, water and M
2onSiO
2after effect, can form as M
2onSiO
2mH
2the hydrate of O, wherein water accounts for overall M
2onSiO
2mH
2the content of O hydrate is between 50 weight percent to 70 weight percents.
Preferably, inorganic silicate frie retardant coating of the present invention is water-soluble inorganic silicate frie retardant coating.
Preferably, inorganic silicate frie retardant coating of the present invention is applicable to coating on various large substrates, for example: wall, roof, plank, floor dividing plate, reinforcing bar, furniture, cable etc., so that required fire prevention and flame retardant effect to be provided, the number of times occurring to reducing fire.
The present invention separately provides a kind of preparation method of inorganic silicate fireproof jointing sheath; it comprise by one as the aforementioned inorganic silicate frie retardant coating be applied on a substrate; and solidify the inorganic silicate frie retardant coating on this substrate, so as to form an inorganic silicate fireproof jointing sheath on this substrate.
Preferably, described preparation method can coat inorganic silicate frie retardant coating of the present invention on one substrate in modes such as spraying, roller coating or brushings, and forms this inorganic silicate fireproof jointing sheath after it solidifies.
Preferably, the thickness that this inorganic silicate fireproof jointing sheath is formed on substrate can be between 50 microns (um) to 2 millimeters (mm).
Preferably, inorganic silicate fireproof jointing sheath of the present invention is transparent inorganic silicate fireproof jointing sheath.
According to the present invention; described inorganic silicate frie retardant coating is mainly in air, to see through carburizing reagent silica gel content is increased; relend by the evaporation of free water molecule and become solid silica with Silicagel dehydration; and setting and harden; so as to forming transparent inorganic silicate fireproof jointing sheath, its carburizing reagent formula is as follows:
M
2O·nSiO

2. the preparation method of inorganic silicate fireproof jointing sheath of the present invention
Inorganic silicate frie retardant coating of the present invention can be applicable to coat on a substrate, and so as to protection, fire prevention and fire-retardant effect are provided, its preparation method is as described below.
First, provide a metal substrate, its material is iron, can be 900 square centimeters for the area of coating, and the thickness of metal substrate is 0.3 centimeter.
Then; prepared inorganic silicate frie retardant coating in aforementioned each embodiment is brushed and coated respectively on different metal substrate with brush; and be statically placed in air and reached 24 hours; carry out carburizing reagent by airborne carbonic acid gas; then carry out dehydration reaction it is solidified, can on this metal substrate, form the inorganic silicate fireproof jointing sheath that a thickness is about 150 microns.
3. the fire-retardant and flameproof effect of test inorganic silicate frie retardant coating of the present invention
Coat fire prevention and the fire retardancy of the inorganic silicate fireproof jointing sheath forming after metal substrate for testing inorganic silicate frie retardant coating of the present invention; as shown in Figure 1; the present invention is placed in the metal substrate 1 of inorganic silicate fireproof jointing sheath that is formed with each embodiment the opening A ' of High Temperature Furnaces Heating Apparatus A; and utilize the opening A ' of this metal substrate 1 closed high temperature stove A, so as to utilizing fire prevention and the fire retardancy of High Temperature Furnaces Heating Apparatus A test inorganic silicate fireproof jointing sheath.
In this test case, its one side (take this face as positive) by the metal substrate that is coated with inorganic silicate fireproof jointing sheath, towards the inside of High Temperature Furnaces Heating Apparatus, is directly heated inorganic silicate fireproof jointing sheath by High Temperature Furnaces Heating Apparatus.In heat-processed, measure respectively the temperature of the another side (back in the back side in aforementioned front) of metal substrate at different heating temperature with infra-red thermometer, to detect fire prevention and the flame retardant effect of inorganic silicate fireproof jointing sheath of each embodiment.In this, measured experimental result is as shown in following table 3 and table 4.
Table 3: after the substrate with the inorganic silicate fireproof jointing sheath of embodiment 1 to 4 heats under differing temps, the substrate surface temperature of another side.
Table 4: after the substrate with the inorganic silicate fireproof jointing sheath of embodiment 5 to 8 heats under differing temps, the substrate surface temperature of another side.
Refer to shown in Fig. 2, it solidify to form in the schematic diagram of a substrate 1 for inorganic silicate fireproof jointing sheath 2 of the present invention.Before with 200 °, temperature more than C does not heat, the thickness of inorganic silicate fireproof jointing sheath 2 of the present invention is about micron grade; When it is with 200 ° after temperature more than C heating, inorganic silicate fireproof jointing sheath 2 ' by the decades of times that is expanded to original volume to hundreds of times, so as to good fire prevention and flame retardant effect is provided.
Confirm through experimental result; after the heat of the inorganic silicate fireproof jointing sheath of various embodiments of the present invention with 200 ° of C; inorganic silicate fireproof jointing sheath surface after expanded by heating is by forming the air curtain being made up of the sealed gas chamber of multiple partial vacuums state, therefore required flameproof effect and flame retardant effect can be provided.
In addition; another by the metal substrate with inorganic silicate fireproof jointing sheath of embodiment 1; be coated with inorganic silicate fireproof jointing sheath (take this face as positive) with gas gun direct heating; and measure the surface temperature of the another side (back in the positive back side) of the uncoated substrate that has inorganic silicate fireproof jointing sheath, to verify fire prevention and the flame retardant effect of inorganic silicate fireproof jointing sheath.
In this test condition; inorganic silicate fireproof jointing sheath is formed at approximately 400 microns of thickness on substrate; it is taken 5 substrates and tests respectively the back temperature that is subject to hot substrate, and calculates the mean value of the back temperature after this 5 group substrate is heated, to obtain the average back temperature of this substrate.
Back temperature test result after the inorganic silicate fireproof jointing sheath of table 5: embodiment 1 heats at different heating time and temperature.
Refer to shown in table 5 and Fig. 3; result via fire line test confirms; in the time that the coated on one side of substrate has inorganic silicate fireproof jointing sheath of the present invention; even if base plate heating is to the high temperature of about 500 ° of C; its average back temperature still can be maintained at 55 ° below C; show that inorganic silicate frie retardant coating of the present invention really can effectively completely cut off thermal source and be subject to the conduction of heat between hot substrate; and provide good flameproof effect; more can effectively avoid substrate because of being heated and by the situation of sooting or destruction, and then the integrity of protective substrate.
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the claims in the present invention.
