Embodiment 1

[0021] A kind of preparation method of cork floor of the present invention, carry out according to following method steps:

[0022] Put the oak bark into a pulverizer for crushing, and then perform cone milling, put the oak bark particles after cone milling into a vibrating sieve for screening, and then conduct steel milling to obtain granules with a particle size of 0.2-0.8mm and a particle density of 100 grams per cubic decimeter.

[0023] Choose oak bark with a length of 1m, a width of 0.6m, and a thickness of 5mm, put it into an iron cauldron and boil it in water at a temperature of about 80-100°C for 3-4 hours to fully soften it. The layer machine is cut into small pieces of patterned fabrics with a thickness of 0.5-1mm; then the small pieces of fabrics are mixed with 15-20 kg of glue according to 70 kg of material, and stirred at a pressure of 200-400 tons / m 2 The lower compact is put into the furnace and heated at 120°C for 4 hours, cooled after being released from the...

Abstract

The invention discloses a method for preparing cork floor, which comprises the following steps: a, crushing an oak bark into cork granules with the diameter of 0.2 to 0.8 millimeter; b, selecting another oak bark with certain length, boiling and airing the oak bark, splitting the oak bark into small pattern fabrics, mixing and stirring the pattern fabrics and polyurethane glue solution, pressing the mixture into a blank, heating and cooling the blank, and cutting the blank into sheet pattern fabrics; c, mixing and stirring the cork granules and the polyurethane glue solution, pressing the mixture into a blank, heating and cooling the blank, and cutting the blank into sheets to obtain a base material; and d, pressing and compounding the pattern fabrics and the base material gluing solution, and heating, cooling and strickling the mixture to obtain a finished product. The high-pressure density of the cork floor prepared by adopting the method reaches over 600 kilograms, and the surface abrasion resistance thereof reaches over 8,000 turns. The cork floor has the properties of comfort, durability, environmental protection, beauty, sound insulation, heat insulation, moisture resistance, skid resistance, flame retardation, and the like.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a method for preparing a cork floor. Background technique [0002] The existing method of preparing cork flooring with oak bark as a raw material is generally to select raw materials, crush them, press mold the crushed raw material particles, slice the formed cork modules in a slicer, and paste the sliced ​​sheets on The high-density wood-based board is used as a veneer, and then sanded with emery cloth, and the paint is generally sprayed, and then the buckle groove is made, the inspection is packaged, and the finished product is finished. This method has the low density of the cork module formed by compression molding, which is easy to produce pores, and the cut pieces have poor wear resistance, which affects product quality. The method of spraying paint is easy to produce uneven thickness of paint film and bubbling phenomenon on the surface of paint film, which al...
