Problems solved by technology
This kind of fireproof board is not strong, fragile and easy to break
Furthermore, some fireproof boards are equipped with a metal layer to increase the strength of the fireproof board. However, the metal layer and the fireproof material are bonded with an adhesive. Cracking, low safety performance
Moreover, traditional equipment consumes a lot of energy, has low output value, increases labor intensity, and uses unreasonable materials, which leads to a large amount of waste of raw materials; backward technology does not guarantee product quality, and the low utilization rate of waste water leads to waste of water resources. There is no recovery of steam or recycling. low rate

Embodiment Construction
[0030] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.
[0031] A preparation process of an environment-friendly lightweight fireproof board is:
[0032] 1) Mix and stir the raw materials and auxiliary materials according to the proportion to obtain the slurry;
[0033] 2) Coating the slurry on the conveyor belt, sending it into the dehydration forming mechanism for dehydration and plate forming, and obtaining the slab blank with the mould;
[0034] 3) After the slab with the mold is cut and trimmed, it is sent to the resting area for resting;
[0035] 4) Demoulding the rested slabs, and then using steam to perform high-temperature and high-pressure curing to obtain semi-finished products;
[0036] 5) The semi-finished product can be used directly or f...

The invention discloses an environment-friendly light fireproof plate preparation technology and an environment-friendly light fireproof plate preparation device. The preparation technology comprises the steps of: 1, mixing materials with auxiliary materials according to a proportion and stirring to obtain slurry; 2, coating the slurry on a conveying belt, sending into a dewatering and forming mechanism to dewater and made into plates, and thus obtaining plate blanks with molds; 3, cutting and finishing the plate blanks with molds and sending into a rest area for having a rest; 4, demolding the rested plate blanks, performing high-temperature and high-pressure maintenance by steam, and thus obtaining semi-finished products; 5, drying and shaping the semi-finished products for directly using or further processing. A device for practicing the environment-friendly light fireproof plate preparation technology is also provided. The light fireproof plates with high shock resistance can be prepared by employing the technology and the device provided by the invention. The invention can be applicable to the field of production of fireproof plates.
Description
technical field [0001] The invention relates to the technical field of building material preparation, in particular to a preparation process and equipment for an environment-friendly impact-resistant lightweight fireproof board. Background technique [0002] At present, the general fireproof boards on the market use fireproof materials as the base material. Pour the pasty fireproof material into the mold, then extrude / roll to form, solidify, enter the drying room for drying, trim, and pack. Can be finished. This kind of fireproof board is not strong, fragile, and easy to break. Furthermore, some fireproof boards are equipped with a metal layer to increase the strength of the fireproof board. However, the metal layer and the fireproof material are bonded with an adhesive. Cracking, the safety performance is not high. Moreover, the traditional equipment has high energy consumption, low output value, increased labor intensity, unreasonable use of materials, resulting in a la...
