Description
Technical field
The present invention relates to one residential plumbing or the technical field of the light plastic inspection shaft of sewage disposal system, especially
It is a kind of light-duty phenoplasts inspection shaft and preparation method thereof.
Background technology
Plastic inspection well is that urban construction plumbing or sewage disposal system substitute the big of the brick inspection shaft of conventional cement
Type, complicated plastic part, are the important building material products for promoting China's green ecological environment city-building.Plastic inspection well is by carrying
Intensity can be divided into light-duty, plain edition and heavy type, the light-duty greenery patches for being applied to forbid motor vehicles to enter, passage, cycle track or
Pavement, plain edition is applied to the road or holding area of 10T grades of automobile and its following vehicle pass-through, and heavy type is applied to 10T grades
Above motor vehicles current road or holding area.Light plastic inspection shaft applies in general to one residential（Residential neighborhoods,
Public building area, garden etc.）In the range of forbid motor vehicles enter greenery patches, passage, cycle track or pavement, its buried depth
Degree is not more than 6m, hole diameter in below 700mm.
At present, one residential draining light plastic inspection shaft is generally made up of well lid, well room and well seat, material therefor master
If with the thermoplastic or thermoplastic plastic composite material for matrix such as PVC, PE, PP, injection molding processing.Thermoplasticity is moulded
Expect that advantage is that injection molding process is functional, but have the disadvantage that product strength is difficult to improve, case hardness is relatively low, yielding；For
Raising product strength, plastic inspection well general wall thickness increases to more than 10mm, thus material cost is high.
Phenoplasts are also known as bakelite, are necessarily to match by phenolic resin, filler, plasticizer, lubricant and curing agent etc.
Combination, and by being heating and curing as phenoplasts product, it is phenoplasts high mechanical strength, tough and tensile relative to thermoplastic
Wear-resisting, dimensionally stable, purposes are wide, and phenoplasts are divided into two major classes with processing mode：The thermoplastic phenolic resin of injection molding processing
Fat plastics and the thermosetting phenolic resin plastics of hot-forming processing (plastic moulds technology handbook, China Machine Press,
1997.6,ISBN 7-111-05348-6).Thermoplastic phenolic resin is line style resin, and three-dimensional will not be formed in building-up process
Network structure, curing agent is must be added in further solidification process, and this resinoid is also known as two-stage resin;Thermosetting phenol
Urea formaldehyde, it is a kind of resin containing the methylol active group that can further react, if synthesis is uncontrolled, can be made
Polycondesation is carried out to molten, the insoluble solidified resin with three-way network structure is formed always, and this resinoid is also known as
For single order resin.Phenoplasts are using phenolic resin as matrix, and filler is then important component, and its consumption and performance are to moulding compound
Performance has a major impact, traditional phenoplasts using wood powder or bamboo powder as main stuffing, be aided with a certain amount of inorganic filler prepare and
Into cost is low, handling ease, and it is to solve existing plastic inspection well skill to use the phenoplasts inspection shaft using phenolic resin as matrix
The effective way of art problem.
The content of the invention
The technical problem to be solved in the present invention is：In order to solve the existing light plastic inspection shaft skill in above-mentioned background technology
There is provided a kind of light-duty phenoplasts inspection shaft and preparation method thereof for the problem of art is present.

It is drying standby as 50-80 mesh dusty materials.
Wood powder：Wood powder is added in thermoplastic phenolic resin, plastic material cost can be reduced, reduction phenolic resin is crisp
Property, improve product size stability；It is wood powder, wood powder material to select the wood materials such as log, waste wood, waste and old wood furniture and crush
Material is cheap, be easy to get, easy processing, environmental protection.
Described toughener is to use polyamide PA injection particle industry product, and preparing turns into 50-100 mesh dusty materials.
Toughener：PA (polyamide) possesses phenolic resin intrinsic toughening function, 200 DEG C or so of PA fusion temperatures；In post processing
In solidification process, the fusing of PA powder, and by chemical modifications such as grafting, block polymerizations, introduce or the flexible base of increase phenolic resin
Group or flexible chain, reach the purpose of effective tough-increased phenolic plastic inspection well, improve product strength.
Described curing agent uses hexa commercial grade.
Curing agent：Hexa curing catalysts, when thermoplastic phenolic resin temperature reaches 170-200 DEG C, with
The ortho para position of phenylol is reacted in thermoplastic phenolic resin, produces crosslinking curing, is formed and is not melted insoluble solid-state phenolic aldehyde modeling
Material.
Described talcum powder uses 50-100 mesh quartz sand industrial goods.
Talcum powder：Quartz sand has the characteristics such as lubricity, anti-stick, sharp flowing, is conducive to thermoplastic phenolic resin injection to fill
Fill out mold cavity.
