[0025] In parts by weight, put 30 parts of wood flour fiber, 6 parts of pectinase and 100 parts of water in the No. 1 beaker, and place the No. 1 beaker in a digital speed measuring constant temperature magnetic stirrer at a temperature of 32°C , At a speed of 400r / min, heating and stirring for 60 minutes to obtain a mixed solution, and then filter the mixed solution to obtain a filter residue, and then place the filter residue in an oven and dry to a moisture content of 3% to obtain dry wood flour fiber; Dry wood flour fiber and isocyanate are placed in the No. 2 beaker according to the mass ratio of 1:30, and the No. 2 beaker is placed in the digital display speed constant temperature magnetic stirrer, and the speed is 400r / min. Stir and immerse for 40 minutes. And then filter the impregnating solution to obtain modified wood flour fiber; add wood flour particles and 30% potassium permanganate solution with a mass ratio of 1:100 into the No. 3 beaker, and place the No. 3 beake...

Abstract

The invention discloses a composite wood plastic building template and belongs to the technical field of a building material. The composite wood plastic building template is prepared by the followingsteps: ball-milling and mixing rice husk powder, activated wood powder particles, activated sheet-like wood powder, petroleum resin and terpene resin to obtain mixed materials; ball-milling and mixingpolyvinyl chloride resin powder, 8,8-di[4-(2,3-epoxypropoxy)phenyl]pentadecane epoxy resin, phenolic resin and ethanediamine to obtain mixed resin materials; stirring and mixing the obtained mixed materials and the obtained mixed resin materials, heating and kneading, and heating and mixing to obtain mixed materials; and drying the mixed materials, drying, and performing compression molding forming and demolding to obtain the composite wood plastic building template. The composite wood plastic building template provided by the invention has excellent mechanical property.

Description

Technical field [0001] The invention discloses a composite wood-plastic building template, which belongs to the technical field of building materials. Background technique [0002] Since the 1990s, the building structure system has undergone great changes. Cast-in-place reinforced concrete structures take up an increasing proportion of civil engineering, and high-rise and super high-rise reinforced concrete buildings have emerged in large numbers. The construction of cast-in-place concrete structures requires the use of building templates. The building template structure is mainly composed of three parts: panels, supporting structures and connectors. Among them, the panel is a bearing slab, which is in direct contact with the newly poured concrete and is a bearing slab; the supporting structure is a temporary structure that supports the panel, concrete and construction load; the connector can be used as an accessory to connect the panel and the supporting structure Connect as ...
