Abstract
The present invention discloses a kind of low foamed multi-layer plastic building template and preparation method, is used for the building operations concrete pouring.This template is made of sandwich layer and the top layer that is covered in the sandwich layer two sides, and template is plate, grooved or perpendicular type.Described top layer and sandwich layer are base-material with the olefin hydrocarbons thermoplasticity plastics all, and both components and content are different, contain fire proofing in the top layer, contain blowing agent and temperature regulato in the sandwich layer.Respectively the difference batching is added two extruders during making, clamp-on the layering shaping dies after the melting simultaneously, extrude continuously and make the tabular template, also can further be processed into grooved or perpendicular type template through moulding form.This template surface layer abrasion-proof, fire-retardant, good toughness, in light weight, the good rigidly of sandwich layer, whole strong and unyielding combination strengthens combination property; The easily demoulding, easy to clean help the template repeated use and scrap the back reclaiming.
Description
Technical field
The present invention relates to a kind of construction formwork that is used for pouring concrete construction, particularly low foamed multi-layer plastic building template, and relate to the preparation method of this template.
Background technology
In the engineering construction processes such as building, bridge, tunnel, the essential a large amount of template of concrete pouring.Various templates are also constantly updating, and mainly contain wooden form, steel form, bamboo offset plate etc.What application was more at present is wooden plywood, in light weight, easy to use, but is limited to the second-rate of sheet material and cementing agent, uses and has just scrapped for 3～5 times, waste resource, recovery difficulty.Also there are many deficiencies in the plastic formwork of building trade appearance recently, the hardness height, the poor toughness that have, and easy embrittlement, bad processing, the rigidity that has is not enough, and is yielding.Chinese patent 99111262.8 discloses a kind of glass fiber reinforced low foaming plastic architectural template, it is a base-material by thermoplastic, add glass fiber, blowing agent and other filler, through extruder hot melt extrusion molding, improved formwork rigidity, access times are many, reduced cost, have made marked progress, but still following shortcoming is arranged: 1, this template by making with the compound of a kind of component and content, can not be taken into account the rigidity and the toughness of template from outside to inside simultaneously, and its combination property is not good enough; 2, this template is a hollow structure, and concrete easily pierces in the cavity during use, is difficult to remove, and brings difficulty to reclaiming; 3, in corner's when construction that is used for members such as beam, post, use inconvenient.What 4, this mould material produced when the construction cutting is pure last, splashes human body and scratches where it itches unbearable, unhealthful.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, a kind of good combination property, easily demoulding, easily recovery are provided, can improve efficiency of construction, reduce construction cost, be of value to the low foamed multi-layer plastic building template of health, and its preparation method is provided.
Technical scheme of the present invention is: low foamed multi-layer plastic building template is made of sandwich layer and the top layer that is covered in the sandwich layer two sides, and the component of described sandwich layer and content (weight) are:
Base-material 98%～99.7%;
Blowing agent 0.1%～0.3%;
Blowing temperature conditioning agent 0.05%～1.2%;
Wetting agent 0.05%～1%;
The component on described top layer and content (weight) are:
Base-material 60%～90%;
Fire proofing 9%～35%;
Wetting agent 0.1%～5%;
Above-mentioned base-material is the olefin hydrocarbons thermoplasticity plastics, and described template is plate, grooved or perpendicular type.
Further scheme is: described olefin hydrocarbons thermoplasticity plastics are any of polypropylene, polyethylene, polyvinyl chloride, or polypropylene, polyethylene be with the mixture of any ratio, and above thermoplastic can be a virgin material, also can be reworked material; Thick 0.4～the 1.2mm in described top layer, the thick 10～18mm of sandwich layer; Described blowing agent is barium azodicarboxylate, Celogen Az, to toluene sulphur chloro urea, 4,4 '-OBSH, triple-well base triazine, oxalyl hydrazine or dinitrosopentamethylene tetramine; Described blowing temperature conditioning agent is the oxide of zinc, lead, cadmium or barium; Described wetting agent is a liquid polyisobutene, low-molecular-weight paraffin wax or animal fat; Described fire proofing is any in antimony oxide, molybdenum oxide, cupric oxide, zinc oxide, aluminium hydroxide, magnesium hydroxide, the Firebrake ZB.
Technical solution of the present invention be on the other hand: the preparation method of low foamed multi-layer plastic building template is as follows: olefin hydrocarbons thermoplasticity plastics 60%～90%, fire proofing 9%～35%, the wetting agent 0.1%～5% of following component and content (weight) by the comminutor granulation, are sent into extruder again after mixing; Olefin hydrocarbons thermoplasticity plastics 98%～99.7%, blowing agent 0.1%～0.3%, blowing temperature conditioning agent 0.05%～1.2%, the wetting agent 0.05%～1% of following component and content (weight) are sent into another extruder after mixing stirring, the compound of two extruders after with melting clamp-oned the layering shaping dies simultaneously, extrude continuously and make the tabular construction formwork, cut by specification after the cooling processing.
The tabular construction formwork of making can further be processed into grooved or perpendicular type construction formwork through moulding form before the cooling fully.
Low foamed multi-layer plastic building template of the present invention is made of sandwich layer and top layer, and the component and the content on sandwich layer and top layer are different, thickness is also different, after deliberation and test, has determined scientific matching, the top layer is smooth, wear-resisting, fire-retardant, good toughness, sandwich layer is in light weight, and good rigidly is sawed, construction processing such as nail easily, template realizes strong and unyielding combination, has improved combination property.This template is the entity plate, and middle do not have a cavity, and concrete can be stained with into inside during use, easily the demoulding, easy to clean, help the repeated use of template and scrap after reclaiming, help reducing construction cost.This template has plate, grooved, perpendicular type various types simultaneously, is used for the concrete pouring of members, particularly its corner such as beam, post, is convenient to splicing and installs, and can effectively improve efficiency of construction.This template does not contain glass fiber, is of value to health.Utilize two plastic extruders to carry out layering progressive forming in the preparation method of the present invention, and, can guarantee the template crudy through typing, cooling processing in conjunction with prior art.
