Embodiment 1

[0024] A solid polymer foam building formwork, comprising the following components and their respective mass fractions:

[0025]

[0026]

[0027] The production method of the above solid polymer foam building formwork includes mixing preparation, extrusion molding and cooling steps, and finally enters the traction. After traction, it is produced according to the length of the required formwork according to the mold size. The selected mold size is 200mm× 15mm; the extrusion molding step is to use a 65 / 132 twin-screw extruder to extrude after heating; the heating temperature is: 170°C in the first zone, 170°C in the second zone, 183°C in the third zone, and 198°C in the fourth zone , 190°C in the fifth zone, and 147°C in the confluent core.

[0028] Among them, the cooling step is to use electric heating water to cool and set the shape. Specifically, the extruded template enters the special water cooling water tank for the setting mold.

[0029] On the basis of the modif...

Abstract

The invention discloses a solid-core polymer foaming building template and a production method thereof. The solid-core polymer foaming building template comprises the following components in percentage by mass: 40-60% of recyclable PVC door-window waste, 20-30% of PVC-8 type resin, 3-10% of CPE-135A, 1-4% of heat stabilizer, 0.2-0.8% of PE-WAX, 0.3-0.8% of silicon dioxide, 0.1-0.6% of carbon cellulose, 1-4% of alkali-free glass fiber, 0.2-0.5% of stearic acid, 0.5-2.5% of monostearin, 0.5-2.5% of aluminate, 5-14% of light calcium carbonate, 0.2-1.3% of a foaming stabilizer, 0.5-1.5% of a foaming conditioner, 0.1-0.3% of a white foaming agent and 0.2-1.2% of a yellow foaming agent. The production method comprises the steps of mixture preparation, extrusion molding, cooling and traction, and the building template is produced in mold sizing according to required template length after the traction. Through the adoption of the solid-core polymer foaming building template, the PVC door-window waste coming from a recycling market accounts for about 50% of the formula, and other new chemical materials only account for about 50%, the component proportion in the formula is proper, the product is energy-saving and environment-friendly, and the aim of recycling the resource is achieved.

Description

technical field [0001] The invention relates to a solid polymer foamed building formwork, and also relates to a production method of a solid polymer foamed building formwork, which belongs to the field of plastic plates. Background technique [0002] PVC foam board is a new type of plastic material developed abroad in the 1970s. Due to its unique production technology, it has excellent performance and is widely used in construction, vehicles, furniture, decoration, advertising production, exhibitions Signage, city appearance and environmental protection, tourism and other industries. Hard-crust low-foaming PVC sheet is one of the materials with excellent performance. In recent years, the production of low-foaming extruded products in my country has made considerable progress, but the scale, product variety and quality are all in line with the development of my country's chemical building materials market. The situation is not suitable, and the relevant formulations, process ...
