Description

A kind of composite-making process of the stability without penetrated wood and wood plastic product
Technical field
The present invention relates to the composite article preparation field of a kind of timber and wood moulding, espespecially a kind of stability without penetrated wood with The composite-making process of wood plastic product.
Background technique
Currently, in order to save resource and cost, many wood furnitures have used timber and wood moulding viscous in common woodwork The composite plate connect, but the durability of current composite plate is poor, on the one hand, under long-time use, it is easy degumming and makes to tie Structure layer is detached from, and composite plate is caused to lose using required intensity and stability, on the other hand, by four seasons climatic effect, in tide Interim over wet south wind day, cementability dies down between the structural wythe of composite plate, and bonding agent penetrates into plank or wood moulding Plate surface layer, plank or wood-plastic board are seriously affected using quality, under by glue infiltration and moisture effect so as to cause composite plate Can not weatherability, humidity, further result in the shortening of service life;Furthermore such as selection of general timber and wood moulding is bad, work Skill is not careful, is easy the defects of there are warpages, deformation, causes composite plate to use unstable, such as when climate changes, summer is easy Temperature distortion, the easy damp damages plate quality of south wind Tianrong, in terms of comprehensive, use process can not safety guarantee.
Summary of the invention
To solve the above problems, the present invention is directed to disclose the composite article preparation field of a kind of timber and wood moulding, espespecially one Kind composite-making process of the stability without penetrated wood and wood plastic product.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of stability is without penetrated wood and wood plastic product Composite-making process, which is characterized in that the preparation process mainly comprises the steps that
S1, binder is prepared:
Primary raw material component are as follows: 22.3 parts of acetal resin, 16.4 parts of polyacrylamide amine emulsifier, 8.5 parts of epoxy resin, Virgin's milk 3.9 parts of glue, 8.7 parts of curing agent, 0.89 part of cellulase, 0.76 part of talcum powder, modified 8.1 parts of tree ash, dimethicone 2.9 Part, 0.45 part of ammonium sulfate, 3.3 parts of barium stearate, 2.81 parts of negative ion powder, 3.1 parts of polyvinyl alcohol, 0.6 part of vinyl acetate, propylene 0.8 part of acid butyl ester, 4.1 parts of polyurethane prepolymer;By the way that by component, successively hybrid reaction to be prepared is used for wood moulding and plank Preparation and cementing binder;
S2, timber-work is prepared:
Primary raw material are as follows: log 27-42%, remaining sawdust 38-47%, waste and old rotten wood 12-26%, natural resin 0.5-6%, binder 5-12%;
Firstly, selecting, rubber wood is log and to cut be plate shape to obtain spare timber one, then, remaining sawdust and useless Old rotten wood is the raw material collected after processing, and sufficiently pulverizes the two progress to form mixing particle, finally will mixing particle and day Right resin, binder be mixed and are sufficiently merged in a heated condition to obtain spare timber two;
S3, wood plastic product is prepared:
Primary raw material are as follows: waste paper 2-10%, foaming waste material 3-11%, high molecule plastic 23-30%, natural fiber 21-29%, wooden slag 30-40%, binder 8-16%;
Firstly, waste paper mixing liquid is polished into secondary stock, secondly it will heat and mix after foaming waste material, high molecule plastic and roll At mixing particle, wooden slag is rolled into wood powder material, secondary stock, mixing particle, wood powder material are then mixed into stirring with natural fiber, Injection binder continues to stir, and obtains lay-by material three;
S4, prepare mold:
Prepare timber molding die and wood moulding molding die, wherein the die cavity bottom surface of timber molding die is set as honeycomb table Face, the die cavity bottom surface of wood moulding molding die are set as the overshooting shape surface closed with honeycomb table face paste;Then prepare planar shaping mould Tool;
S5, casting:
First spare timber two is paved with thin layer to timber molding die bottom, is then alternatively arranged block-like spare timber one It is laid on thin layer surface, is then filled on top surface by spare timber two, to obtain wood after three period intervals are heated Material product;Finally lay-by material three is filled into wood moulding molding die, to obtain wood moulding after three period intervals are heated Product;And 2-4h is interior for semi-solid state after the cooling period for timber-work, the wood plastic product after heating;
S6, composite molding:
Semi-consolidated timber-work, wood plastic product demoulding are taken out, are rapidly injected heating at the two surface especially honeycomb notch Timber-work, wood plastic product, are then fitted and connected, using laser irradiation 12- by the binder that temperature is 56 DEG C from honeycomb table face After 28 minutes, pressure bonding molding;
S7, the shallow pore of another surface imprint from timber-work, wood plastic product after compound, are laid with a layer binder, and binder seeps Enter and distinguishes wood plastic product thin slice, the timber-work of compound adhesion 0.8-1.2mm on the surface of timber-work, wood plastic product after pore Thin slice;Obtain four-layer structure composite article;
S8, fire resistant coating is coated on the surface of composite article, composite article finished product is obtained after drying.
The log that the step S2 prepares timber-work can also be cherry, black walnut or pine.
The wooden slag that the step S3 prepares wood plastic product can be the list in white rubber, yellow jacket, ash wood, beech or Manchurian ash Only wooden slag or mixing wooden slag.
In the step S5, spare timber one with a thickness of 2-4mm, spare timber two with a thickness of 5-14mm, and two Person is to surround package assembly;Lay-by material three with a thickness of 4-12mm.
In the step S5, three period interval heating are respectively for the first time with 110-125 DEG C of heating, standing 3.5h It is heated afterwards with 80-94 DEG C, stands 2.5h and heated with 55-61 DEG C, last sub-cooled.
