Abstract
The invention discloses a plastic-wood composite material furniture assembly fixation method, which is characterized in the following technological process: (1) forming a guide hole in a plastic-wood composite material needing component fixation; (2) filling the guide hole with glue; (3) naturally airing for 20-30 minutes, and enabling the glue to form a glue film with better stickiness on the inner wall of the guide hole; (4) screwing a self-tapping screw into the guide hole, wherein the inner diameter of the guide hole is equal to the outer diameter of the self-tapping screw, the glue is a mixture of polystyrene and methylbenzene, and the mass ratio of the polystyrene to the methylbenzene is 4 to 6. After the glue is aired, the polystyrene part in the glue is volatilized, and the formed glue film is stuck to the inner wall of the guide hole, and is naturally concave in the middle.
Description
Technical field
The invention belongs to furniture manufacture field, be specifically related to a kind of Wood plastic composite furniture construction fixing means.
Background technology
Wood plastic composite refers to adopt and obtains other plant fiber-like material to fill containing wood-fibred and strengthen a kind of composite of modified thermoplastic, and main component is plastics and wood powder.Material wherein containing wood-fibred class comprises waste wood powder, bamboo powder, sawdust, wood shavings and waste wood etc.; Other plant fiber comprises agricultural crop straw, rice husk, peanut shell and various wastes of flax etc.Thermoplastic adopts polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and polystyrene (PS) etc. usually, can adopt virgin material, also can adopt reclaimed materials, or both also uses.
As a kind of new material between timber and plastics, Wood plastic composite has a series of property being better than timber and plastics: the secondary workability having wood appearance and similar wood, and water imbibition little, be not afraid of and damage by worms, crack and buckling deformation can not be produced as timber; There is the processability of thermoplastic, but hardness is higher than plastics, wear-resisting, ageing-resistant, corrosion-resistant.Adding of various auxiliary agent can give its more property: as not raw fungi, good flame resistance, anti-strong acid and strong base etc.Add colouring agent, overlay film or composite skins and can be made into the goods with various color attractive in appearance and decorative pattern.Especially to it is worth mentioning that, not only the process raw material waste plastics and culled wood that can adopt recovery of Wood plastic composite, and itself also recyclable recycling, to minimizing environmental pollution, protect forest resources significant.
Wood plastic composite, as a kind of environment-friendly materials, possesses the advantage of string and plastics simultaneously, almost can contain the use field of all logs, plastics, plastic-steel, aluminium alloy and other similar composites.Meanwhile, Wood plastic composite has the advantage being easy to mould various different shape, can design various shape, so be widely used at furniture industry.
The furniture item self-tapping screw of current most of Wood plastic composite fixes, in an assembling process, when self-tapping screw is screwed into parts, the portion of material of furniture material inside can be extruded under the effect of screw thread, the internal diameter in the hole that self-tapping screw is screwed into increases to some extent, after self-tapping screw is tightened, easily there is false fixing phenomenon.As long as when parts receive larger External Force Acting, self-tapping screw often very easily comes off, cause parts to depart from Furniture Body, affect the use of furniture item.In addition, when carrying after dismounting furniture, often needing when reinstalling furniture to use new uterus screw to be screwed in new position, causing the waste of screw and the breakage of furniture outward appearance.Therefore, most furniture adopts injection glue to fix in assembled position, and self-tapping screw just plays positioning action.But, there is many problems in the method, although glue can bond Wood plastic composite fastening, but the characteristic on Wood plastic composite surface can be destroyed, damage to a certain degree can be caused when bond site part is accidentally impacted, and the parts damaged cannot be changed, and bring difficulty to product reparation.In addition, because the glue dries time is longer, certain influence is had to the production capacity of mass production.Meanwhile, because parts are adhesively fixed with glue, the volume of furniture entirety is comparatively large, increases the difficulty of packaging, and damaging to prevent furniture item needs to use a large amount of paper honeycomb to pack it, and considerably increase packing cost, economic benefit is not good.
Summary of the invention
In order to overcome above-mentioned technological deficiency, the invention provides and a kind ofly install firmly, pack easy Wood plastic composite assembling fixing means.
In order to realize above-mentioned purpose of the present invention, a kind of Wood plastic composite furniture construction fixing means of the present invention, is characterized in that carrying out according to following technological process:
1) on the Wood plastic composite needing fixation kit, pilot hole is processed;
2) in pilot hole, glue is filled;
3), after naturally drying 20-30 minute, described glue forms the good glued membrane of one deck viscosity at pilot hole inwall;
4) self-tapping screw nail is screwed in described pilot hole.
Further, more firm in order to ensure assembling, described pilot hole internal diameter equals self-tapping screw external diameter.
Further, described glue is the mixture of polystyrene and toluene, and the mass ratio of polystyrene and toluene is 4:6.
Further, after described glue dries, the toluene part volatilization in glue, glued membrane and the pilot hole inwall of formation bond, middle depression naturally.
Compared to prior art, a kind of Wood plastic composite furniture construction fixing means provided by the invention can guarantee that self-tapping screw nail can not be extruded material because of threaded function when being screwed into, the glued membrane that only can be formed at glue forms identical screw thread, avoid the damage to the hole that Wood plastic composite furniture is screwed into, it also avoid the infringement of glue to furniture material surface, self-tapping screw nail prevents false fixing phenomenon, even if also can not come off when being subject to external force collision.Meanwhile, adopt a kind of Wood plastic composite furniture construction fixing means of the present invention, make furniture packaging simple and easy, greatly reduce packing cost.
