Abstract

A composite thermal insulation board of forest residues and polystyrene foam relates to a composite board. The composite thermal insulation board can solve the problems of great consumption, high cost, low strength, flammability, difficult repeated utilization and serious environmental pollution of the polystyrene foam thermal insulation board in the construction field. An expanded polystyrene thermal insulation layer (2) of the utility model is arranged in the middle of a first forest residue scrap composite layer (1-1) and a second forest residue scrap composite layer (1-2); the upper surface of the first forest residue scrap composite layer (1-1) is adhered to the lower surface of the expanded polystyrene thermal insulation layer (2); and the upper surface of the expanded polystyrene thermal insulation layer (2) is adhered to the lower surface of the second forest residue scrap composite layer (1-2). The composite board has low cost, high strength, flame retardation, effective and reasonable utilization of forest residues, repeated utilization and small environmental pollution. The composite board is widely applied to the construction field.

Description

Forest tree remainder and polystyrene foam composite insulation boards

Technical field

The utility model relates to a kind of composite insulation boards.

Background technology

Existing polystyrene foam heat preservation plate material is widely used in fields such as building, packings, and the trend of phenomenal growth is arranged.But the polystyrene foam heat preservation plate material also has weak point, and, recycling difficulty low, inflammable such as cost height, intensity and environmental pollution are serious etc.

The utility model content

The utility model has solved that existing polystyrene foam heat preservation plate material cost height, intensity are low, inflammable, recycling difficulty and to the with serious pollution problem of environment, and a kind of forest tree remainder and polystyrene foam composite insulation boards are provided, and the concrete technical scheme that addresses the above problem is as follows:

The utility model is made through mechanical compression by the first forest tree remainder particle composite bed 1-1, expanded polystyrene (EPS) heat-insulation layer 2 and the second forest tree remainder particle composite bed 1-2, expanded polystyrene (EPS) heat-insulation layer 2 is located at the centre of the first forest tree remainder particle composite bed 1-1 and the second forest tree remainder particle composite bed 1-2, the upper surface of the first forest tree remainder particle composite bed 1-1 and the lower surface bonds of expanded polystyrene (EPS) heat-insulation layer 2, the lower surface bonds of the upper surface of expanded polystyrene (EPS) heat-insulation layer 2 and the second forest tree remainder particle composite bed 1-2.

The utility model be utilize forest tree remainder through chipping, flaking is processed into woody debris, in particle, add adhesive, auxiliary agent is made compound insulating material, make forest tree remainder obtain effective utilization, this composite insulation boards cost is low, intensity is high, fire-retardant, its thermal conductivity factor is 0.05W/ (m.k), compressive strength is 250kPa, and can reuse and environmental pollution little.This composite insulation boards is widely used in building field.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the cutaway view of Figure 1A-A.

The specific embodiment

The specific embodiment one: describe present embodiment in conjunction with Fig. 1.Present embodiment is made through mechanical compression by the first forest tree remainder particle composite bed 1-1, expanded polystyrene (EPS) heat-insulation layer 2 and the second forest tree remainder particle composite bed 1-2, expanded polystyrene (EPS) heat-insulation layer 2 is located at the centre of the first forest tree remainder particle composite bed 1-1 and the second forest tree remainder particle composite bed 1-2, the upper surface of the first forest tree remainder particle composite bed 1-1 and the lower surface bonds of expanded polystyrene (EPS) heat-insulation layer 2, the lower surface bonds of the upper surface of expanded polystyrene (EPS) heat-insulation layer 2 and the second forest tree remainder particle composite bed 1-2.

The specific embodiment two: present embodiment is whittled into wood chip with forest tree remainder with wood chipping equipment earlier, be processed into woody debris, through super-dry, dried woody debris is put into mixer high pressure spray while stirring glue, with the lay one deck in mould of the particle after the high pressure applying glue, the layer of polystyrene foam that layer overlay is handled with glue on the good high pressure spray glue particle of lay, and then lay one deck high pressure sprays the glue particle on layer of polystyrene foam, promptly makes forest tree remainder and polystyrene foam composite insulation boards after the machinery pressurization.

The first forest tree remainder particle composite bed 1-1 and the second forest tree remainder particle composite bed 1-2 act as enhancing, sound insulation, expanded polystyrene (EPS) layer 2 act as heat-insulation layer, thereby increased the intensity and the heat-insulating property of composite insulation boards, quick for installation, cracky not.
