Embodiment 1

[0025] Step 1: Put the bamboo into a mill to grind into bamboo fibers, and get 4 mesh particles after sieving, and then dry them in an oven at 110°C for 24 hours to keep the average moisture content of bamboo fibers at 7%;

[0026] Step 2: Crush the porcelain stone and put it into a pulverizer for grinding. After sieving, 80 mesh porcelain clay particles are obtained

[0027] Step 3: Weigh 60% of China clay particles, 28% of bamboo fiber, and 12% of adhesive by weight percentage, mix China clay particles, polyisocyanate adhesive (EMDI) and water first to obtain a pasty mixture, and then add the adhesive and water The weight ratio in the mixture is 1:2, and then the mixture and bamboo fiber particles are evenly mixed and paved into a slab of 400mm×400mm; the thickness is 13-14mm.

[0028] Step 4: put the slab into an ordinary hot press machine, the pressure is 6MPa, the hot pressing temperature is 190°C, and the hot pressing time is 7 minutes; get: 400mm×400mm×12mm bamboo porc...

Embodiment 2

[0034] Step 1: Put the bamboo into the mill to grind into bamboo fibers, and get 6-mesh particles after sieving, and then dry them in an oven at 110°C for 24 hours to keep the average moisture content of the bamboo fibers at 8%;

[0035] Step 2: Crush the waste porcelain stone and put it into a pulverizer for pulverization treatment. After sieving treatment, 60 mesh porcelain clay particles are obtained

[0036] Step 3: Weigh 40% of china clay particles, 48% of bamboo fiber, and 12% of adhesive by weight percentage, mix the china clay particles, polyisocyanate adhesive (EMDI) and water first to obtain a pasty mixture, and place the adhesive and water in The weight ratio in the mixture is 1:2, and then the mixture and bamboo fiber particles are evenly mixed and paved into a slab of 400mm×400mm; the thickness is 13-14mm.

[0037] Step 4: put the slab into an ordinary hot press machine, the pressure is 6MPa, the hot pressing temperature is 180°C, and the hot pressing time is 6 m...

Embodiment 3

[0043] Step 1: Put the waste material after bamboo processing into a mill to grind into bamboo fibers, and obtain 8-mesh particles after sieving, and then dry them for 24 hours in an oven at a temperature of 110°C to make the average bamboo fiber The moisture content is kept at 9%;

[0044] Step 2: Crush the waste porcelain stone and put it into a pulverizer for grinding treatment. After sieving, 40 mesh porcelain clay particles are obtained

[0045] Step 3: Weigh 28% of china clay particles, 57% of bamboo fiber, and 15% of adhesive by weight percentage, mix the china clay particles, polyisocyanate adhesive (EMDI) and water first to obtain a pasty mixture, and the adhesive and water in The weight ratio in the mixture is 1:2, and then the mixture and bamboo fiber particles are evenly mixed and paved into a slab of 400mm×400mm; the thickness is 13-14mm.

[0046] Step 4: put the slab into an ordinary hot press machine, the pressure is 5MPa, the hot pressing temperature is 180°C,...

Abstract

The invention discloses a bamboo and ceramic composite board, which is characterized by comprising the following components by mass ratio: 40 to 60% of bamboo fiber, 28-60% of ceramic powder and 12 to 15% of adhesive. The composite board takes a bamboo fiber in bamboo processing waste and a green waste material in a ceramic processing enterprise as main raw materials and is prepared by working procedures of material stirring, pavement molding, hot-pressing curing, drying and maintaining and the like. The board prepared by the method can fully utilize the production waste in bamboo processing and ceramic processing enterprises, so that the huge cost is saved, and the major measures of eliminating pollution, purifying the environment and turning waste into treasure are taken; and meanwhile, the produced composite board has better waterproof resistance and flame retardancy as well as stronger mechanical properties.

Description

technical field [0001] The invention relates to a bamboo-porcelain composite board and a processing method thereof, belonging to the technical field of wood-based panels Background technique [0002] In recent years, with the continuous increase in the production of bamboo products, the leftovers, leftovers, and bamboo tips of bamboo processing enterprises have not been utilized. Except for a very small part that is used to produce bamboo chopsticks, most of them cannot be processed. These "three wastes" Either used as fuel or discarded everywhere, not only the resource utilization rate is less than 50%, the waste of resources is great, and new pollution is formed. [0003] Under the social background of the country's vigorous development of "low-carbon economy", the ceramic industry with high energy consumption, high pollution and high waste rate has also attracted people's attention. With the rapid development of the ceramic industry, ceramic industry waste is increasing ...
