Add the power agent: 0.05% waterproofing agent: 0.1%
The preparation method of flooring substrate, carry out successively according to the following steps:
A, chip: wooden butt is sent to conveyer belt manufactured the wood chip that length is the 36-40 millimeter in the wood chipping equipment;
B, flaking: by scratch board conveyor the above-mentioned wood chip of making is transported to chipper and manufactures the flaking that thickness is the 0.35-0.45 millimeter;
C, drying: above-mentioned flaking is transported to rotator type drying machine inner drying, moisture wood chip is dried to percentage of moisture 0.5-1.5%;
D, glue mixing: with classified table material and the core material of sieving into of dried wood chip, access top layer material glue and core layer material glue according to technological requirement, wherein curing agent, additive, waterproofing agent add during with glue at modulomenter, sandwich layer, then top layer material and surface layer adhesive are added in the glue mixer of top layer simultaneously, moisture content after the glue mixing is 10-12%, and resin added is 8-9%, and core layer material and sandwich layer glue are added in the sandwich layer glue mixer simultaneously, moisture content after the glue mixing is 7-8%, and resin added is 13-14%;
E, mat formation: the material that will show, the sandwich layer glue mixer comes out mixes the back simultaneously and adds in the spreading machine feed bin, rolls by the plate dry body that is combined into arts demand on the conveyer belt that drops on the spreading machine bottom behind the wood shavings thickness sorting by diamond;
F, hot pressing: above-mentioned plate dry body is sent to hot press by metal tape, and the hot press operating pressure is 260Mpa, and breadth is 2650 * 14900mm, and platen temperature is 150-260 ℃ up and down, and the floor base material hot pressing time is 2.5-3 minute, and unit pressure is 30-35Kg/cm
3, temperature is 180-200 ℃;
G, cooling are stacked: the hair plates that hot press is come out places on the more smooth breezy buck frame and cools off, and cuts into specification then;
H, sanding, check: sanding be with hair plates up and down pre-hardening thickness remove, carry out grade classification by the inspector according to the plain plate of company standard after simultaneously to sanding;
I, packing, shipping: carry out protective packaging by company standard, according to the customer requirement shipping.
The wood floor base material of the present invention's preparation, glue consumption is few, and content of formaldehyde is few, and burst size of methanal is also few.With the laminated flooring that this base material is made, burst size of methanal only is 1/8 of a national standard, and timber utilization rate improves 30%, and intensity and stationarity all are better than the timber floor with the MDF making.The wood floor base material sample survey of the present invention's preparation the results are shown in following table:
| Interventions Requested | Standard-required | Assay |
