specific Embodiment approach 1

[0023] Specific implementation mode one: reference figure 1 , a wooden mold-coated building template in this embodiment is to paste a layer of veneer 2 on the upper and lower surfaces of the core board 1 made of waste templates. The thickness of the veneer 2 is 0.8-1 mm, and then the A layer of veneer is pasted on the surface of the veneer 2 on the upper and lower surfaces of the veneer, and the thickness of the veneer is 0.5-3mm. Each layer of veneer is composed of a polyolefin material layer 4 and a non-woven fabric 3, and the non-woven fabric 3 is located between the veneer 2 and the veneer. Between the polyolefin material layers 4; the polyolefin material layer 3 is composed of 85%-100% polyolefin and 0-15% filler by mass percentage, and the filler is talcum powder or calcium carbonate powder.

specific Embodiment approach 2

[0024] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the thickness of the veneer (2) is 1-2.5 mm, the thickness of the veneer is 1-2 mm, and the polyolefin material layer (4) is made according to The mass percentage is composed of 90%-95% polyolefin and 5%-10% filler. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0025] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the thickness of described veneer (2) is 1.8mm, the thickness of veneer is 1.5mm, other is identical with specific embodiment one or two.

Abstract

The invention discloses a plastic-coated wooden building template and a preparation method thereof, which relate to a building template and a preparation method thereof and mainly solve the problems that a high-cost performance building template prepared by the current preparation method is low in turnover times and poor in mechanical properties. The preparation method comprises the following steps: firstly, manufacturing a core plate by using a waste template; secondly, manufacturing a polyolefin veneer coated with non-woven fabric; thirdly, gluing double sides of a wood veneer, putting the wood veneer between the polyolefin veneer coated with the non-woven fabric and the core plate, with the same operation for upper and lower surfaces; and finally, pressing. The turnover times of the plastic-coated wooden building template is as high as 30-35 times, which is 10-17% higher than that of the current building template, so that the using cost of the plastic-coated wooden building template is reduced; the plastic-coated wooden building template has the bending strength of 52-55 MPa and an elasticity modulus of 6050-6210 MPa; the plastic-coated wooden building template is high in strength and good in toughness; the preparation method is simple, low in cost and easy to implement, and is applicable to large-scale popularization and application; and the plastic-coated wooden building template has relatively high economic and social benefits and can be applied to the building engineering.

Description

technical field [0001] The invention relates to a building template and a preparation method thereof. Background technique [0002] Formwork is an indispensable tool for the construction of concrete structures, which directly affects the quality, speed, cost and economic benefits of construction companies. At present, the main purposes of waste formwork on the construction site are firstly recycling waste products, secondly used by the project department for side wall maintenance, and thirdly used as construction slag and dragged away, so the use value of waste formwork is low; Low frequency technical issues. [0003] The existing patent number is 201210519303.5, a Chinese patent named "A Cost-effective Building Formwork and Its Preparation Method", which discloses a building formwork and its preparation method. The formwork is made of a core board made of waste formwork and The upper and lower surfaces are composed of polyolefin material layers and non-woven fabric veneer...
