Problems solved by technology

[0002] Plastic templates, building springboards, and decorative panels have been researched and produced in small batches using new raw materials and recycled recycled materials, but so far, most of them use high-density polyethylene (HDPE) and polypropylene (PD). After foaming and other means, due to factors such as material performance, price, and craftsmanship, its shortcomings such as poor rigidity, low-temperature impact resistance, UV resistance, and thermal expansion and contraction cannot be widely used, and it can be sawed and nailed poorly during use. , There will be a gap of about 1 cm between the board and the board (1×2M) in the morning and evening construction at noon, and the formwork will bulge at noon in the morning and evening construction

Embodiment 1

[0054] A recycled plastic composite reinforced foam template, including a thickness of 12-15mm and a capacity of 0.3-0.8g / cm3 The middle foam layer 3 is laid with an upper reinforcement layer 2 on the upper end surface of the middle foam layer 3, and an upper skin layer 1 is compounded on the upper reinforcement layer 2; The reinforcement layer 4 is compounded with the lower skin layer 5 on the lower reinforcement layer 4; the upper skin layer 1, the upper reinforcement layer 2, the foam layer 3, the lower reinforcement layer 4 and the lower skin layer 5 form an integral structure with a thickness of 14-60mm , the bulk density is 0.6-6.82 g / cm 3 .

Embodiment 2

[0056] A recycled plastic composite reinforced foam template described in Embodiment 2 is basically the same in structure as Embodiment 1, the difference is that: the upper end surface of the upper skin layer 1 is compounded with an upper anti-slip layer 6, and the lower skin layer The lower end face of 5 is compounded with lower anti-skid layer 7.

[0057] The epidermis thickness in embodiment one and two is 0.8-1.2 mm, and bulk density is 1-1.2 g / cm 3 The reinforced layer is steel wire mesh or glass fiber mesh; the anti-slip layer is 2-3 mm thick, and is composed of chlorinated polyethylene elastomer mixed with 40-80 parts of 20-30 mesh quartz sand, and then hot extruded on the composite skin layer.

Embodiment 3

[0059] A recycled plastic composite reinforced foam template and production method, comprising the following steps:

[0060] 1. Take 100 parts of recovered waste plastic PC, ABS or SBS, add 3-5 parts of MAN and 0.05-0.3 parts of DCP, extrude through a Φ75 parallel twin-screw extruder, and cut into pellets after water cooling to make PC, ABS or The grafted modified raw materials of SBS are stored separately for subsequent use;

[0061] 2. Raw materials for preparing the middle foam layer and the skin layer:

[0062] According to the ingredient ratio of PC:ABS:PET=10-30:55-70:5-10, take PC, ABS, SBS prepared in step 1, add 5-7 parts of phase solvent, and pass through parallel twin-screw extruder Hot extrusion graft modification, and granulation for later use; extrusion temperatures were 126, 131, 145, 168, 196, 212, 236, 251°C;

[0063] 3. Prepare the middle foam layer:

[0064] Take the raw material prepared in step 2, add 0.2-1.5 parts of foaming agent, mix evenly, use SJ-1...

Abstract

The invention provides a reclaimed plastic composite enhanced foaming mold plate and a production method. The reclaimed plastic composite enhanced foaming mold plate is characterized by comprising a middle foaming layer; the middle foaming layer is 12 to 15 mm in thickness and 0.3 to 0.8 g / cm<3> in volume weight; an upper enhancement layer is laid on the upper end surface of the middle foaming layer; an upper surface layer is compounded on the upper enhancement layer; a lower enhancement layer is laid on the lower end surface of the middle foaming layer; a lower surface layer is compounded on the lower enhancement layer; and the upper surface layer, the upper enhancement layer, the foaming layer, the lower enhancement layer and the lower surface layer adopt an integral structure which is 14 to 60 mm in thickness and 0.6 to 6.82 g / cm<3> in volume weight. The main raw material of the reclaimed plastic composite enhanced foaming mold plate is waste plastic, so as to change waste into valuable, and reduce cost. The reclaimed plastic composite enhanced foaming mold plate can be used for manufacturing a mold board, a gangboard and a decorative board, is high in bending resistance, tensile strength and anti-impact property, light in weight, high in moisture-proof and anti-corrosion performances, and long in service life.

Description

technical field [0001] The invention relates to a building board, in particular to a composite reinforced foam plastic board used for building springboards, templates and decorative boards. Background technique [0002] Plastic templates, building springboards, and decorative panels have been researched and produced in small batches using new raw materials and recycled materials, but so far, most of them use high-density polyethylene (HDPE) and polypropylene (PD). After foaming and other means, due to factors such as material performance, price, and craftsmanship, its shortcomings such as poor rigidity, low-temperature impact resistance, UV resistance, and thermal expansion and contraction cannot be widely used, and it can be sawed and nailed poorly during use. , There will be a gap of about 1 cm between the board and the board (1×2M) in the morning and evening construction at noon, and the formwork will bulge at noon in the morning and evening construction.
