Description
Technical field
The present invention relates to the recoverying and utilizing methods of pine waste material, and in particular to a kind of to discard sawdust as raw material preparation using pine
The method of light decorative plate.
Background technology
Pine is a kind of confierophyte, and the growth cycle of pine is long, annual ring is fine and closely woven, the quality of timber is flexible, and trees contain
Oil mass is low, and the two tone colour of itself is evenly distributed, it have rosin taste, color is yellowish, furuncle scar is more, to atmospheric temperature reaction soon,
It is easy to swell, the characteristics such as extremely difficult natural air drying, therefore need to be through artificial treatment, such as drying, degreasing remove organic compound, and bleaching is unified
Color is set, tree property is neutralized, is allowed to be unlikely to deform.
Be in the past do not make furniture with pine because pine be easy it is dry and cracked, but since modern likes what pine brought
Log feels and environmental protection, and pine furniture is generally the least expensive in solid wood furniture, so, it is more and more with the people of pine furniture.
Pine furniture has following features：1, color and luster is natural, maintains the natural gray of pine, and texture understands beauty；2, moulding is simple
Generous, the full smoothness of lines shows completely and well adds texture；3, highly practical, durable；4, elasticity and gas permeability are strong, thermal conductivity
It can get well and maintenance is simple.Pine furniture has merged the manufacture of modern furniture while protrusion nature, steady reality, rough style
Technique.With increasing for pine furniture, the usage amount of pine increases, and many leftover bits and piecess are just produced during making furniture
Material, wood shavings discard sawdust etc., and usual people directly abandon pine waste, landfill is carried out when fertilizer or as industrial fuel
Burning, according to analysis, utilization rate when pine waste combustion is not high, and the combustion heat is undesirable, wastes resource, while generation of burning
Flue gas pollute the environment.
Invention content
The purpose of the present invention is providing a kind of new recoverying and utilizing method for the waste generated in pine process, have
Body be to provide it is a kind of discarding the method that sawdust prepares light decorative plate as raw material using pine, this method can largely recycle pine
Wood waste, manufactured light decorative plate is with highly practical, durable, ageing resistance is strong, good toughness, soundproof effect are good
The features such as, and naturally feel with log, it is goodlooking.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
A method of sawdust is discarded using pine and prepares light decorative plate as raw material, is included the following steps：
(1) the following raw material is weighed in parts by weight：Pine discards 60-70 parts of sawdust, 4-8 parts of adhesive, 1000 mesh quartz
15-20 parts of powder, 600 10-20 parts of mesh silica flours, 60 5-10 parts of mesh quartz sands, 40 5-10 parts of mesh white glass, nano-titanium dioxide
0.5-1 parts, 0.05-0.1 parts of coupling agent, 0.05-0.1 parts of curing agent；
(2) raw material for weighing step (1) is uniformly mixed, and obtains mixture；
(3) mixture is packed into mold, through pressure machine vibration compression moulding, obtains profiled sheeting；
(4) cure at a temperature of profiled sheeting being placed in 90-105 DEG C, hardening time is 20-30 minutes；
(5) after the completion of curing, natural cooling, sanding and polishing.
Further, the pine discards sawdust, is that the sawdust, wood shavings, leftover bits and pieces left when processing pine is collected, so
After carry out defibrator process, sawdust is made, using sieve filter out length be 5-15mm sawdust, you can obtain pine discard sawdust.First
Pine is made by process above and discards sawdust, then carries out preparing light decorative plate, sawdust is distributed evenly, and shape is more preferable
See, plate forming it is closer, more robust, can make decorative panel obtained has the characteristics that pine, appearance more have log
Feel, more resistant to seeing.
Above-mentioned technical proposal, preferably, described adhesive is made of resin and waterglass.Because in the formula of the present invention
The particularity of the intercombinations such as pine sawdust, silica flour, glass, titanium dioxide, it is necessary to be equipped with the adhesive for being suitble to its performance, such as
Fruit adhesive selects bad, then each raw material is not easy to be bonded together, even if being easy to decline if bonding good quality；Suitable is viscous
Mixture can be quick and lasting each raw material of bonding, make made of light decorative plate it is high-quality, it is durable.
Above-mentioned technical proposal, preferably, the mass ratio of the resin and waterglass is 10-20：1.
Above-mentioned technical proposal, preferably, the resin is made of Resin A and resin B；The Resin A is Lauxite
(UF), the one or more of melamine resin (MF) and Polyamide-Polyamsne-Epichlorohydrin (PAE)；The resin B is
The one or more of saturated polyester resin, acrylic resin, epoxy resin, epoxy-ester.
Above-mentioned technical proposal, preferably, the Resin A is Polyamide-Polyamsne-Epichlorohydrin (PAE)；The resin B
By acrylic resin and epoxy-ester with 1-3：1 mass ratio composition；The mass ratio of Resin A and resin B is 10：1-2.
Above-mentioned technical proposal, preferably, the coupling agent is titanate coupling agent and/or four n-propyl zirconates.
Above-mentioned technical proposal, preferably, the curing agent is peroxidized t-butyl perbenzoate, diamino-diphenyl first
It is one or more in alkane, dibenamine base ether, m-xylene diamine.
Above-mentioned technical proposal, preferably, in step (3), the parameter of the pressing operation process is as follows：Pressure is 700-

The characteristics of each component and the degree of influencing each other are set, and keep the performance of manufactured decorative panel good and goodlooking.
Advantageous effect：
The present invention provides a kind of new recoverying and utilizing method, and preparation process for the waste that pine process generates
Simply.This method can largely recycle pine waste, reduce the waste of resource and as environment caused by fuel combustion
Pollution.
The present invention has the characteristics that centainly to inhale noise using pine and keeps the temperature, by with after other Raw material processings, it is manufactured
The soundproof effect of decorative panel is good, and has certain heat-insulating property.
Not sun-proof after furniture is made in usual pine, light is easy to change after irradiating, wears, aging, and the present invention adds in formula
A certain amount of titanium dioxide is entered, there is good anti-ultraviolet function, integrated the function of adhesive, coupling agent, curing agent, has led to
Crossing decorative panel made of special technique has good anti-aging property, plank slow using rear aging speed.
Contain a certain amount of pine tar in pine, so pine furniture often will produce peculiar smell, and pine sawdust can also remain
Certain pine tar, for the present invention by the way that pine sawdust to be combined with other raw materials, it is different that manufactured decorative panel can solve pine generation
The problem of taste.
The material of pine be it is very tough and tensile slim and graceful, it is slimmer and more graceful than general decorative panel using decorative panel made of pine sawdust,
Use scope is wide, in addition its good toughness, is unlikely to deform and is broken.
The present invention selects the material matching of rational granular size, makes each component assembled arrangement regularly, plate obtained
Material density is big, and hole is small, can not only substantially reduce the dosage of various auxiliary agents, more environmentally friendly, while impact flexibility is high.System of the present invention
At light decorative plate have the characteristics that highly practical, durable, ageing resistance is strong, good toughness, soundproof effect are good, and
Naturally feel with log, goodlooking, good visual effect.
