Description
Technical field
The present invention relates to thermoplastic composite fields, and in particular to there is the building template preparation of hard abrasive material on a kind of surface
Method.
Background technique
Currently, generally using three categories building template: 1. wooden multi-plywoods in building field；2. steel form；3. bamboo
Sheet, in addition to this, there are also plastic template, above-mentioned template is generally existing to wear no resistance, rigidity/mass ratio is low, creep-resistant property
Difference, fatigue performance be poor, perishable, not easy mold release, the disadvantages of service life is short.It is all existing for traditional architecture template in order to solve
More problems, building template made of the various composite materials of R & D design, wherein galss fiber reinforced resin is obtained as building template
Popularization and application are arrived.Glass fibre assigns the mechanical properties such as composite material high strength degree as the reinforcing material met in material, with
Fiberglass reinforced plastics enhances the intensity of plastic building template as building template.But fiberglass reinforced plastics is still deposited
It is used the shortcomings that wearing no resistance, and as building template, after surface abrasion, the randomness of glass fibre makes reinforced plastics surface
It is extended with glass fibre, when preparing concrete using the building template, after concrete hardening, the glass fibre meeting of reinforced resin
It protrudes into concrete, influences concrete demoulding.
Summary of the invention
To solve the above problems, the present invention provides the building template preparation method that there is hard abrasive material on a kind of surface, using
Glass fibre, reinforced plastics building template are added in the building template, there is hard abrasive material on surface, improves the resistance to of plastic building template
Mill property extends plastic building template service life.
The object of the present invention is achieved in the following manner:
There is the preparation method of the building template of hard abrasive material on a kind of surface, contains glass fibre in building template, there is hard on surface
Abrasive material；The glass fibre accounts for the 10-30% of building template weight；The hard abrasive material is diamond, cubic boron nitride, oxidation
One of silicon, silicon carbide are a variety of, account for the 5-10% of building template weight；According to following carry out step:
Step 1: release agent is coated on the molding tool surface of required building template shape, hard abrasive material is mixed by mass fraction
It closes uniformly with sand-blasting gun even application in molding tool inner surface；
Step 2: plastic raw materials are introduced into double screw extruder melting from plastic feed, set extrusion temperature as 100 DEG C -290
℃；
Step 3: glass continuous filament yarn is introduced into double screw extruder, the plastics of glass fibre and melting from fiber feed mouth
By infiltration runner mixture；
Step 4: it is pulled out through the outlet of extrusion die by dragger, the glass fiber reinforcement that formation length is 5-20mm after pelletizing
Plastic grain；
Step 5: it in molding tool needed for fiberglass reinforced plastics obtained above is fitted into, is pressed into through 120-290 DEG C
Type, cooling and demolding ultimately form the building template that there is hard abrasive material on the surface.
Further, the hard abrasive material is according to diamond: cubic boron nitride: silica: silicon carbide is the weight of 3:3:2:2
Than combination.
Further, in addition to glass fibre, hard abrasive material, antioxidant, plastic additive, crosslinking are also added in building template
It is agent, coupling agent, one or more in inorganic filler.
Further, the release agent is that methyl-silicone oil is dissolved in toluene, is configured to the silicon oil solution that quality is 2%.
Compared with the existing technology, the present invention can bring have the beneficial effect that glass fibre be uniformly dispersed to melting
In combine glass fibre sufficiently with melting charge, reinforced plastics, by molding tool with sand-blasting gun uniformly by hard abrasive material
It is sprayed on the wearability that molding tool inner surface increases plastics, extends the service life of building template.
