Fireproof wave-absorbing plate

Technical Field

The invention relates to the field of building materials, in particular to a fire-proof suction wave plate.

Background Art

The building material as the ecological corn production process does not exist in the problems of pollution to the environment. If the raw material to cure, the development of the ecological function has different use of a building product, will greatly reduce the consumption of wood. The resistivity of the silicon carbide is between metal and the semiconductor, has a small density, has good high-temperature resistant property, wide absorption band, multi-band wave-absorbing material is an important component. The invention utilizes silicon carbide filling corn stalk, not only can demonstrate the wave-absorbing performance, but also can effectively improves the wear resistance.

Content of the invention

In response to the deficiencies in the prior art, the purpose of this invention is to provide a fire-proof suction wave plate.

Production of this invention comprises the steps of:

(1) purification of corn

(2) grinding and sieving corn stalk powder

The particle size of corn stalk powder 30-40 mesh.

(3) carbonization corn stalk powder

corn stalk powder into the high-pressure processing of the pot, in subsequently from the tank is introduced into the high-pressure saturated steam, the pressure to rise to 0.25 MPa, preserving the temperature and the pressure for 4 hours, the final pressure-relief, pressure is taken out after the cutting.

(4) drying corn stalk powder

At the temperature has been already preheated to 100 the defibrater [...] in the dry.

(5) by adding flame retardant and cementing agent urea-formaldehyde resin, and hot grinding corn stalk powder

Flame retardant synthetic process adopts the following: dicy, phosphoric acid, triethanolamine and water, according to the 5 [...] the 3 [...] the 2 [...] 10 heating quality of the mixed proportion of dissolved, in 85-95 the insulation under the conditions of [...] 3-4 hours, cooling to 60-70 the after [...] , the added mass ratio the 6 [...] the 4 [...] 3 of boric acid, borax, ammonia, boric acid quality dicy quality 6%, thermal insulation after dissolving the discharge reserve. Flame retardant and cementing agent is urea-formaldehyde resin mass ratio the 3 [...] 10, flame retardant is the quality of corn stalk powder 8%.

The fire retardant and cementing agent urea-formaldehyde resin is added in the milling chamber defibrater, corn stalk powder together with mechanical action, by grinding, in the fiber are mixed and penetrate corn. Saturated steam pressure 0.8-0.9 MPa, milling chamber pressure is 0.7-0.8 MPa, cooking time is 3-5min, the static disk of the abrasive grinding side clearance is 0.2 mm, the degree of balance 0.04 mm.

(6) adding silicon carbide and titanate coupling agent

corn stalk powder quality of the silicon carbide to 12%, the quality of the titanate coupling agent corn stalk powder 1.2%. Silicon carbide particle size is 60-80 mesh.

The silicon carbide and titanate coupling agent in the high-speed stirrer mixing stirring 5 min, then adding in the ball mill, and mixed uniformly corn stalk powder , and by utilizing ultrasonic oscillation the meter causes silicon carbide are uniformly dispersed in the matrix of corn.

Because the silicon carbide is extremely vulnerable to electrostatic, in particular under the action of the friction shear, so it is easy to be exclusive. caking, is not easy to be dispersed. In a high speed stirrer, a titanate coupling agent coated silicon carbide can prevent static electricity, so that the silicon carbide is dispersed evenly. Furthermore, organic titanate to silicon carbide surface activation processing, to improve the compatibility of the silicon carbide and corn stalk powder.

Reasonable silicon carbide particle size can be fill the gap between the fiber from corn stalk, help to improve the binding performance of the board, the strength of the reinforcement and density, and fine silicon carbide particle size will lead to reduced strength, silicon carbide particle size is determined according to the test.

(8) pressure fire-proof suction wave plate

Pressure is 3 MPa, temperature is 170 the [...] , the pressing time is 12 min.

(9) forming

According to product requirements for cutting fire suction wave plate.

The invention has a good fire resistance, wave-absorbing ability, the characteristics of high wear resistance.
