Abstract

The utility model relates to a plastic and wood powder composite building profile material made of plastic and powder of plant stalk, which is characterized in that the cross section of the building profile material is L-shaped; a plurality of ribs are arranged on the inner side and outer side of the L-shaped cross section profile material along the length direction of the profile material; the plastic can be polyethylene, polypropylene or polyvinyl chloride; the wood powder content in the plastic and wood powder composite building profile material is 20% to 65%. The utility model has the advantages that the cross section is L-shaped, the interior angular strip and the exterior angular strip of the room such as ceiling angular strip and door line can be conveniently decorated; the ribs arranged on the inner side and outer side of the L-shaped cross section profile material along the length direction of the profile material beautify the appearance and improve the intensity of profile material; the profile material can be planed, sawed and nailed like timber due to the adoption of plastic and wood powder composite material. The utility model has the advantages of low maintenance cost, good mechanical property, small thermal deformation and water absorption, strong corrosion resistance performance, and good structure and performance.

Description

Plastic wood flour composite material building section bar

Technical field

The utility model relates to a kind of building structure and decorative sections, the building structure that particularly a kind of plastic wood flour composite material is made and the section configuration of decorative sections.

Background technology

In the prior art, the interior linea angulata of decorative house and outside when linea angulata such as roof linea angulata and entrance line, mostly adopt plastic plate or wood-based panel to be cut into lath and be used for decorating roof linea angulata and entrance line, in when finishing owing to will cut out bar and be assembled into the angle to sheet material, so it is pretty troublesome, bad as the assembly unit connection, not only influence intensity, not attractive in appearance yet.When finishing, as adopt plastic plate, and then plastic plate mostly is to be composited with plastics and inorganic powder such as limestone, French chalk etc., this sheet material is very crisp, thermal deformation is bigger, during use, be difficult for adopting carpenter's method for processing processing usually such as plane, saw, nail, as adopting wood-based panel, then water imbibition is big, easy deformation, cracking, corrosion-resistant, maintenance cost is higher during use.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of convenient plastic wood flour composite material building section bar that performance is good, maintenance cost is low of decorating roof linea angulata and entrance line.

The utility model is realized with the following method.

Plastic wood flour composite material building section bar is the architectural shape that material that the powder with plastics and plant stem is composited is made.The cross section of architectural shape is L shaped, has along the fin of profile length direction on the inner face of L shaped cross section section bar or outside.The plastic wood flour composite architectural materials is to be composited by even mixing of the powder of plastics and plant stem, the common auxiliary agent in the prior arts such as an amount of plasticizing agent that interior plastics in addition of plastic wood flour composite architectural materials and inorganic powder compound tense need add, age resistor, fire retardant, colorant.

Cross section of the present utility model is L shaped, the interior linea angulata of decorative house and outside very convenient when linea angulata such as house corner angle staff and entrance line, on the inner face of L shaped cross section section bar or outside, have along the fin of profile length direction, not only attractive in appearance, the intensity of section bar is increased.Because architectural shape is to be composited with plastics and wood powder, adds man-hour, can be as plane, saw, the nail of timber, maintenance cost is low during use, good mechanical property, and its thermal deformation is little, water imbibition is little, and decay resistance is strong, is a kind of constructional materials of structure and better performances.

Below in conjunction with accompanying drawing, the utility model is further described.

Description of drawings

Fig. 1 is the schematic perspective view that there is the plastic wood flour composite material building section bar of fin the outside;

Fig. 2 is the schematic perspective view that inner face has the plastic wood flour composite material building section bar of fin.

The specific embodiment

Fig. 1, Fig. 2, plastic wood flour composite material building section bar are the architectural shapes that material that the powder with plastics and plant stem is composited is made.The cross section the 1, the 2nd of architectural shape, L shaped, the fin 3,4 along the profile length direction is arranged respectively on the inner face of L shaped cross section section bar or outside.

Plastic wood flour composite material building section bar is to be composited by even mixing of the powder of plastics and plant stem.Method for making is: the plant stem drying, be ground into greater than 10 purpose powder; dry plant stem powder is evenly mixed in banbury with plastics; when mixing; in mixture, also has the common auxiliary agent in the prior arts such as an amount of plasticizing agent, age resistor, fire retardant, colorant; after mixing; mixture comminutor granulation, use extruder extrusion plastic wood flour composite material building section bar at last.

Above-mentioned plastics can be polyethylene, polypropylene or polyvinyl chloride.

Plant stem powder in the above-mentioned plastic wood flour composite material building section bar can be wood powder or crops cane powder, and the content of plant stem powder is 20～65%.
