Description

A kind of building template material

Technical field

The present invention relates to building construction formwork field, particularly relate to a kind of New Type Architecture Mode material.

Background technology

The template adopted in the middle of present building operation is generally punching block, wooden model, bamboo mould, plastic mould.Although punching block is firm, multiplicity is many, and cost is high, weight is large, breadth is narrow, piece is many, and construction transport is inconvenient, and easily get rusty, need to carry out rotproofing, maintenance cost is high; Bamboo and wood mould is lightweight, breadth is wide, piece is few, but its intensity is relatively low, non-watertight, easily goes mouldy rotten, reuses number of times few, and consume green resource in a large number.For addressing these problems, also have and adopt plastics to manufacture template, it is lightweight, is not stained with concrete, often reusable, but its shortcoming to be rigidity bad, yielding; Meanwhile, also there is toughness deficiency in the template of assembling after direct injection moulding, shortcoming easily damaged during working aloft.Disclose a kind of enhanced foaming plastic mould in patent CN1242462A, before go a step further again in the plastic mould technology front had, but the use of whipping agent brings disadvantageous effect to production environment, and the upper and lower wall of template that extrusioning shaping obtains is thicker, than great.

Summary of the invention

The present invention provides a kind of New Type Architecture Mode material with excellent mechanical property and processing characteristics to solve above-mentioned prior art Problems existing, and it is thinner, lighter compared with other template material, cost is low, and rigid-tough balance is good, can reuse and reclaim.

Object of the present invention is achieved through the following technical solutions:

A preparation method for New Type Architecture Mode material, comprises the following steps:

Add in high-speed mixer after polyolefine, toughner, grafts, oxidation inhibitor and lubricant are weighed by proportioning and mix, mixed material is sent in twin screw extruder by the feeder of delicate metering, simultaneously glass fibre adds entrance by glass and adds according to the above ratio, through twin screw high speed shear, mixing, extruded by head, tie rod, air-cooled, pelletizing, drying and packaging, obtain described New Type Architecture Mode material.

Compared with prior art, the present invention has following beneficial effect:

The invention provides a kind of New Type Architecture Mode material, be prepared from through twin screw extrusion process by polyolefin resin and glass fibre, toughner, grafts, oxidation inhibitor and lubricant.It is building plastic template that fiberglass reinforced polyolefine material material of the present invention can be passed through forcing machine continuous extrusion, and template is bilevel hollow corrugated structure, and total thickness is 5-20mm, and individual layer wall thickness is 0.2-2mm, and length and width can cut arbitrarily on demand.

Material of the present invention has excellent mechanical property and processing characteristics, owing to adopting glass fiber reinforcement, and add toughner, gained mould material still possesses high-intensity high-tenacity under the condition of very thin wall thickness simultaneously, overcome common plastics template easy problems of crack when nailing, have cost low, lightweight, rigid-tough balance is good, be easy to the demoulding, reuse often, the plurality of advantages such as size can be changeable, recyclable.And compared with the template of other material of same area, thinner, lighter, be convenient to transport and construction, there is good application prospect.
