Description
Technical field
the present invention relates to the flooring material technical field, are specially the processing method on a kind of bamboo floor.
Background technology
are present, and the bamboo floor is advantages such as quality is better, anti-skid wearable because it has, and enjoy consumers in general to favor, but because the bamboo wood high humidity; Wettability is poor, is difficult for japanning and gummed, easily drying shrinkage, cracking and distortion; And damage by worms easily and go mouldy, patent of invention discloses the manufacturing approach that CN200810163701.1 discloses a kind of composite bamboo floor, and patent of invention CN200610072808.6 discloses bamboo floor producing technology; Solve some above-mentioned problems to a certain extent, the floor quality is relatively poor, insufficient strength; The appearance flaw is more, and industrial chemicals etc. have wasting phenomenon, and production cost is higher.
Summary of the invention
the purpose of this invention is to provide the processing method that a kind of color and luster is even, intensity is high, are done manual work in meticulousr bamboo floor on the surface.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme: the processing method on a kind of bamboo floor may further comprise the steps: (1) bamboo chip force plane; (2) bamboo chip carbonization: during the carbide furnace venting; Closed the boiler lid; Open steam valve, let the sewage in the pipe discharge row's light, shut sewage draining valve then and carry out timing; Steam must be in 10 minutes during advance carbide furnace with the pressure rises in the stove to 0.26Mpa ± 0.01, carry out exhaust keeping stablizing under the situation of air pressure; (3) drying room is dry; (4) bamboo chip adjustable cast iron planes; (5) select materials: comprise concora crush material, middle material, bed material, match colors then; (6) gluing: the bamboo chip after will selecting materials, match colors through gluing machine carries out gluing, adopts the glue that comprises resin, modifier, curing agent preparation, is spliced into the above blanket of one deck bamboo chip, and glue-spread is controlled at 125-150g/m
2
, the resting period is 20-40 minute; (7) hot-forming; (8) sanding: thin principle is carried out sanding after the regulation position is by first light, and sanding pressure moves towards freely, operates steadily with sand paper is principle; (9) four sides adjustable cast iron planes; (10) paint sprays paint: comprise the transparent priming of ground floor, the transparent priming of the second layer, the 3rd layer transparent priming, the 4th layer scratch resistance flour milling lacquer, the scratch resistance flour milling lacquer of layer 5 successively; Every layer is carried out dry solidification after varnishing with lacquer, and behind the 3rd layer of paint dry solidification, also will carry out a sanding.Adding through to the improvement of carbonization technique, coating technique, lacquer spraying technique etc. and new technology has promoted the oeverall quality on bamboo floor, but also has practiced thrift a lot of materials of using, and has reduced production cost.
as to of the present invention preferred, in step (2) the bamboo chip carbonization, carbonization time is divided into Three Estate: a, 2 hours 10 minutes ± 5 minutes; B, 2 hours 5 minutes ± 5 minutes; 2 hours ± 5 minutes.It is dark that first grade carbonization becomes, second grade carbonization Cheng Zhongse, and the Three Estate carbonization becomes light color, processes according to different production demands.
face toward fan to the bamboo chip of just having pulled out retort after the carbonization with ventilating fan, in order to avoid hot gas makes the bamboo chip variable color and influences end product quality as to of the present invention preferred.
conduct is to of the present invention preferred, and in step (4) the bamboo chip adjustable cast iron planes, bamboo chip positive and negative cutting output is stayed the cutting of bluish yellow ratio in the bamboo bar.
conduct is to of the present invention preferred; In step (6) gluing,, be spliced into the above blanket of one deck through selection to concora crush material, middle material, bed material; The concora crush material is a direct stress surface of suppressing as vertically; The concora crush material can be made lamina, and bed material can be made doubling plate with the concora crush material, and concora crush material, middle material, bed material can be made the plate more than three layers.
conduct is to of the present invention preferred, and in step (6) gluing, the proportioning of glue is: resin: 100 parts, and modifier: 5-8 part, curing agent: 3-4 part, ammonium chloride: 1 part, can effectively improve the intensity on floor.
as to of the present invention preferred, resin viscosity is 130-230mPas, and content of free aldehyde is lower than 0.07%, and burst size of methanal is lower than 0.5mg/L, not only environmental protection but also can promote the performance of glue.
conduct is to of the present invention preferred, and during step (7) was hot-forming, during the blanket of concora crush individual layer, longitudinal pressure was 17-18Mpa; Lateral pressure is 4-6Mpa, and the press time is 8 ± 0.5 minutes, and temperature is 85-90 ℃, during the two-layer blanket of concora crush; Longitudinal pressure is 14-15Mpa, and lateral pressure is 13-15Mpa, and the press time is 7 ± 0.5 minutes; Temperature is 85-90 ℃, and during blanket that concora crush is three layers, longitudinal pressure is 17-18Mpa; Lateral pressure is 15-17Mpa, and the press time is 8 ± 0.5 minutes, and temperature is 85-90 ℃.Another effective way to the floor strength enhancing.
As to of the present invention preferred, during step (10) paint sprayed paint, the ground floor quantity for spray was 10-30 gram/M
2
, second layer quantity for spray is 30-70 gram/M
2
, the 3rd layer of quantity for spray is 15-20 gram/M
2
, the 4th layer of quantity for spray is 15-20 gram/M
