Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments.
The wood floor integrally comprises a wood raw material and an additive, wherein the wood raw material is large-diameter wood of poplar with high fiber strength for at least three years, the moisture content of the wood is controlled to be 38-42%, the wood is soft in fiber cells, the rapid plasticization of fibers during the hot pressing of a floor base material is facilitated, the problem that the fibers are continuously plasticized during the primary hot pressing and the floor base material is pressed and pasted for the second time is solved, the surface structure of the floor base material is collapsed due to the continuous plasticization of the fibers, the thickness of a finished floor is uniform, the strength attenuation and the water absorption expansion are increased, the additive comprises glue, alkaline carbon black fuel, a curing agent and active carbon powder, the wood raw material is processed by adopting a multifunctional ultrahigh-density board manufacturing process (the process has already reported the invention patent), and the wood raw material is processed and added.
The glue is melamine modified urea-formaldehyde resin, the application amount of melamine is 7% of the weight of the glue, the environment-friendly performance and the waterproof performance of the produced floor base material are better, the application amount of the glue in each cubic volume of the wood raw material is 50% of the weight of absolute dry fibers, the proportion can ensure the extremely high physical strength and the waterproof performance of the floor base material, and also can have enough fiber cross-weaving force to ensure the deformation resistance and the dimensional stability of the floor base material, the alkalinity of the glue is improved in the glue making process because the ultrahigh-density floor base material is produced, as the floor base material has high density and long hot-pressing factor, the surface of the floor base material is over-cured due to continuous high temperature, the surface of the floor base material is over-hard and brittle, the secondary processing veneering of the floor base material is seriously influenced, and serious quality defects such as dried flowers, whitening, edges, no notches and the like are produced after the veneer, the pH value of the glue is controlled to be 9.0, so that the quality defect of the floor base material can be relieved, in addition, the higher the alkalinity of the glue is, the higher the alkalinity of the produced floor base material is, and the better the antibacterial and mildewproof effects of the floor base material are.
The alkaline carbon black fuel is black alkaline carbon black fuel, the pH value of the alkaline carbon black fuel is 9.0-10.0, the higher the pH value alkalinity of the dye is, the higher the alkalinity of the floor base material is, the better the antibacterial and mildewproof effects of the floor base material are, and the applying amount of the alkaline carbon black fuel is that 40kg of alkaline carbon black fuel solution with the solid content concentration of 15% is added into each cubic wood raw material; in order to increase the application uniformity of the liquid alkaline carbon black fuel, water is added to dilute the liquid alkaline carbon black fuel into a solution with the solid content of about 15%, and then the solution is sprayed into a guniting pipe and fully mixed with wood raw material fibers after being mixed with glue through a metering device and variable control of a screw pump.
The curing agent is a latent curing agent, the curing agent is a mixture solution comprising 33 wt% of toluenesulfonic acid, 17 wt% of morpholine and 50 wt% of water, the pH value of the curing agent is 7.5-8.0, and 5kg of the curing agent is added to each cubic wood raw material; because the floor base material has high density, long hot-pressing factor and large conflict between the curing time of surface layer glue and core layer glue, the surface of the floor base material is easy to influence the later processing of the base material because of applying the acid curing agent, the over-solid strength decay of the glue is accelerated, the surface hardness of a product is increased, the plasticity is weakened, and the later processing of the base material is influenced; when the curing agent is applied, the curing agent is accurately measured by a weightless measuring method, the flow is controlled by the variable quantity of a high-pressure screw pump, and the curing agent is sprayed into a guniting pipe after high-pressure atomization and is fully mixed with wood raw material fibers.
The granularity of the activated carbon powder is 50-100 meshes, the application amount of the activated carbon powder is 1-20 percent of the weight of the activated carbon powder in the oven dry fiber, the activated carbon powder passes through an automatic quantitative application device, then the activated carbon powder is conveyed to a drying pipeline through a pipeline by a fan to be mixed with the wood raw material fiber, the position of an insertion point of the activated carbon powder conveying pipeline entering the drying pipeline and the wood raw material fiber is very important and must be inserted at the position of 200mm of the outlet position of a guniting pipe, if the activated carbon powder is sprayed too early, a fire disaster is easily caused, and if the activated carbon powder is sprayed too late, because the specific gravity of the activated carbon powder is different from that of the wood raw material fiber, after the wood raw material fiber and the glue enter the drying pipeline for dispersion, the activated carbon powder can not be uniformly mixed with the wood raw material fiber and the glue, and the activated carbon powder is mutually caught to cause uneven distribution, therefore, the mixing point of the activated carbon powder and the slurry must be completed at the outlet of the guniting pipe before the slurry is dispersed.
The performance indexes which can be achieved after the floor base material is processed are as follows:
thickness: 8-12 mm;
density: 1000kg/m3～1050kg/m3；
Formaldehyde emission is less than or equal to 0.05mg/m3Less than or equal to 0.124mg/m of national E1 level standard3(climate box method).
The internal bonding strength is more than or equal to 4.5 Mpa;
the surface bonding strength is more than or equal to 3.0 MPa;
static bending strength is more than or equal to 60 Mpa;
water absorption swelling index: the middle part is less than or equal to 1 percent and the edge is less than or equal to 4 percent in 24 hours;
antibacterial and mildewproof properties: the mildew-proof antibacterial national standard is grade 2;
