Abstract

The present invention relates to a power line pole made of a composite material, which can be substituted for cement pole and iron pole, and is made up by using polyester resin material and glass fiber material as main raw material, and adding small quantity of other chemical component and adopting a certain production process. Said invented power line pole is long in effective service life and light in weight.

Description

A kind of electric tower of making of matrix material

The present invention relates to a kind of glass filament reinforced plastics and be called for short the electric tower that matrix material is made, especially a kind of effective use limit for length, light weight, non-maintaining electric tower.

At present, known electric tower mainly contains cement pole, iron tower bar and rod, and still, electric power is eliminated gradually with rod, being applied to the cement pole of transmitting line and iron tower bar as great majority has phenomenon of rupture and perishable heavy and belong to conductor then the time, and maintenance cost is also higher.

The objective of the invention is to solve the deficiency of the said products and a kind of electric power line pole tower of making of matrix material is provided, it not only is available as all electric tower fields such as high-tension line shaft tower, light pole, cross-arm, lightning-arrest bar, microwave tower, has also enlarged electric tower simultaneously and has made raw material range.

Purpose of the present invention can reach by following measure: it is characterized in that choosing according to following major ingredient and weight ratio: 40-60 part vibrin, or Resins, epoxy and resol, 40-60 glass fibre or carbon fiber, 9-11 part porcelain powder or silica powder or light calcium carbonate, 5-7 part pigment, 6-10 part fire retardant, 3-5 part protective agent, 3-5 part solidifying agent.

Purpose of the present invention can also reach by following measure: the optimum weight ratio of each composition is 50 parts of vibrin or Resins, epoxy or resol, 50 parts of glass fibre or carbon fiber, 10 parts of porcelain powder or silica powder or light calcium carbonate, 6 parts of pigment, 8 parts of fire retardants, 4 parts of protective agents, 4 parts of solidifying agent.

The technological process of production: vibrin or above other Ti usefulness resin, porcelain powder or the silica powder of enumerating and light calcium carbonate, pigment, fire retardant, protective agent, solidifying agent are poured stirrer successively into and are mixed and stir evenly, be applied to glasscloth or carbon cloth two sides, Wrapping formed then be inserted in electric tower mould extruding after one hour die sinking get product.

The present invention reaches the parameter of electric power iron tower except that tensile strength, ultimate compression strength, moment of flexure, amount of deflection, shaft moment of torsion, compares with currently available products also to possess following advantage: (1) is in light weight, only is 1/3 of iron tower bar and cement pole, can save trucking costs; (2) starting material do not have the waste of offal; (3) installation costs is lower, and only be 1/5 of iron tower bar man-hour; (4) the comparable iron tower height of the same type of compact design reduces by 20% and do not reduce the use effect; (5) can reduce the electromagnetic intensity of iron tower; (6) can be in preparation raw material directly color matching and needn't brushing paint arbitrarily; (7) starting material 70% are the inorganic materials glasscloth, so working life is long, can use 80 years and cement pole only uses 8-15; (8) the maintenance minimum of Yao Qiuing needn't be cleaned maintenance every year; (9) Chinese People's Anti-Japanese Military and Political College's gas, salt fog, soda acid, wet fastness are stronger than cement pole and iron tower bar, and can anti-aging, fire-retardant, insulation; Not only be applicable to the inland, the regeneration product of coastal especially salt fog prone areas; (10) raw materials cost and production cost only are 1/3 of iron towers.

The present invention is described in further detail below in conjunction with embodiment:

Choosing 50 parts of vibrin, 10 parts of porcelain powder, 6 parts of pigment, 8 parts of fire retardants, 4 parts of protective agents, 4 parts of solidifying agent pours stirrer into and stirs discharging after a hour, be applied to 50 parts of glasscloth two sides respectively, twine while being coated with, the coiled jacket go into electric tower mould extruding after one hour die sinking promptly get the composite electrical shaft tower finished product of outward appearance light.

Claims

1, a kind of electric tower of making of matrix material is characterized in that choosing according to following major ingredient and weight ratio:

Vibrin or Resins, epoxy or resol 40-60 part, glass fibre or carbon fiber 40-60 part, porcelain powder or silica powder or lightweight carbon phenol calcium 9-11 part, pigment 5-7 part, fire retardant 6-10 part, protective agent 3-5 part, solidifying agent 3-5 part.

2, the electric tower of making of matrix material according to claim 1, it is characterized in that: each composition optimum weight ratio is:

50 parts on 50 parts in vibrin or Resins, epoxy or resol, glass fibre or carbon fiber, 10 parts of porcelain powder or silica powder or light calcium carbonates, 6 parts of pigment, 8 parts of fire retardants, 4 parts of protective agents, 4 parts in solidifying agent.
