Abstract
The invention discloses a method for making a novel wood-plastic composite building template from waste plastic. The method comprises the following steps of: rotationally cutting wood serving as a raw material into a wood veneer serving as a processing unit, wherein an inner layer is subjected to hole breaking treatment, and a surface layer is soaked in a phenolic-resin adhesive; grinding the waste plastic by using a grinder and adding a certain amount of modifier to obtain an adhesive; and drying the wood veneer, sizing, assembling and performing hot-press gluing under the control of a thickness gauge to obtain the novel wood-plastic composite building template. The defects of a method for making the wood-plastic composite building template by mixing wood fibers and plastic, assembling and performing die pressing are overcome, so that machining cost is greatly lowered, and the processed novel wood-plastic composite building template has plasticity and intensity.
Description
Technical field
The present invention relates to building material field, relate in particular to a kind of waste or used plastics that utilizes and make novel wood-plastic complex architectural template method.
Background technology
At present, domestic wood-plastic composite building formwork manufacture method mainly is now wood materials to be processed into wood fibre, will be prepared from by the assembly mold pressing behind wood fibre and the plastic milling again.Wood-plastic composite building formwork density is big, and timber intensity is low, the power consumption of polymer processing height, and the cost height has seriously restricted the development of wood-plastic composite building formwork.
Summary of the invention
The purpose of this invention is to provide the waste or used plastics that utilizes that a kind of processing technology is simple, production efficiency is high, performance is good, cost is low and make novel wood-plastic complex architectural template method.It can be widely used in as construction formworks such as building, bridges.
A kind of waste or used plastics that utilizes is made novel wood-plastic complex architectural template method, utilizes timber for raw material it to be peeled into behind the Wooden veneer as machining cell, and wherein internal layer is handled through holes, top layer impregnated phenolic resin glue; Waste or used plastics after mill is pulverized a certain amount of modifier of back interpolation as bonding adhesive.Under finger gauge control, carry out the novel wood-plastic complex architectural template that hot-press gluing forms behind Wooden veneer drying, applying glue, the assembly.
Technical scheme of the present invention comprises the steps:
1, Wooden veneer processing
Behind the transversal one-tenth certain-length of timber, adopt rotary veneer machine to be peeled into the uniform thickness Wooden veneer of 0.5～3.5mm, send into veneer dryer then and be dried to moisture content about 10%.
2, dash board impregnation process
Choosing the surface does not have damaged dry rotary-cut Wooden veneer, takes out after it is flooded in 20～26% water-soluble phenolic resin adhesive and dries, and is dried to moisture content about 10% as dash board 60～80 ℃ of conditions again.Require evenly dipping glue of veneer surface.
3, the inner panel holes is handled
The drying of rotary-peeled Wooden veneer that is used as inner panel is built up the high veneer buttress of 500mm on the holes machine, carry out the broken hole position reason.The distribution in adjacent two veneer holes should be dislocatedly distributed.
4, waste or used plastics is pulverized
Waste or used plastics is sent into super power crusher carry out fragmentation and make powder, adding modifier when making powder is that modifier fully mixes with plastic powders.Waste or used plastics powder size is between 60 orders～80 orders.
5, assembly
Flatten a dash board earlier, utilize duster that modifier and plastic powders are sprayed equably on dash board again, consumption is 500g/mm
2, above then an inner panel being superimposed upon.Same method sprays the inner panel that superposes again after on the inner panel surface that has just superposeed equably with modifier and plastic powders.Spray modifier and plastic powders equably on the inner panel surface again, stack a dash board at last again, form certain thickness slab.Can arbitrarily increase and decrease the quantity of inner panel according to the thickness of template when mating formation, be odd-level but require veneer stack quantity, and the adjacent ply grain of wood is vertical mutually, and the distribution form difference in hole.
6, hot pressing
Send into hot press hot pressing after putting into the slab that paves between two stainless steel backing plates, sheet metal thickness has finger gauge control during hot pressing.The requirement hot pressing time is 2min/mm, and hot pressing temperature is 165 ℃.
7, cutting edge
With cutting edge circular sawing machine in length and breadth, the vertical both sides 25cm lath of saw unhairing side plate is earlier sawed the both sides 25cm lath of unhairing side plate again, obtains having the wood-plastic composite building formwork of certain specification at last.
Beneficial effect: compare with existing wood-plastic composite building formwork process technology, advantage of the present invention is because inner panel has passed through the holes processing, formed continuous plastic bonding layer between the adjacent ply, and, because plastic powders has added modifier equably, formed high-intensity setting course between plastics and the Wooden veneer interface, therefore, the template strength height of processing.Simultaneously, it is simple that this wood plastic composite template processing has technology, is easy to accomplish scale production characteristics such as production efficiency height.
