Description
Technical field
The invention belongs to mold pressing composite board technical fields, particularly a kind of to produce composite board using waste PET bottle piece
Processing technology.
Background technique
Plastics are to pass through high-molecular compound made of addition polymerization or polycondensation polymerized using monomer as raw material
(macromolecules), it is commonly called as plastics (plastics) or resin (resin), can freely change ingredient and body styles,
It is made of the additives such as synthetic resin and filler, plasticizer, stabilizer, lubricant, colorant.
The main component of plastics is resin.This noun of resin is initially the lipid secreted out of by animals and plants and gains the name, such as
Rosin, shellac etc., resin refer to the high-molecular compound not yet with various additives mixing.Resin accounts for about plastics total weight
40%~100%.The basic performance of plastics depends mainly on the person's character of resin, but additive also plays an important role.Some modelings
Material is substantially made of synthetic resin, is free of or less containing additive, such as organic glass, polystyrene.So-called plastics,
It is one of synthetic resin in fact, and shape is similar with the pine resin in natural resin, artificial synthesized by chemical means progress,
And it is referred to as plastics.
But plastic refuse is the important component of municipal refuse such as waste PET bottle piece, but also is constantly being increased
It is long.Therefore, waste PET bottle piece plastics recovery processing is the previous urgent problem in current environmentally friendly face, such as number of patent application
(CN201710893569.9) a kind of wear-resistant plastic composite plate haveing excellent performance is disclosed, the plastic plate wear-resisting property is excellent, machine
Tool intensity is high, and corrosion resistance is strong, high temperature resistant, and antioxygenic property and weather-resistant property are improved, and is the recycling of waste PET plastics
Using providing direction.
Existing waste PET bottle piece has the disadvantage that during preparing composite board
Waste and old PET plastic bottle piece needs to crush the PET bottle piece of recycling during preparing composite plate, existing
Disintegrating apparatus it is not thorough enough for the crushing of PET plastic bottle piece, cause subsequent PET plastic particle in mixed process with it is other
Raw material mixing is not uniform enough, influences the processing quality of composite board；
The existing composite plate using the production of PET bottle piece is formed into laminated plastics plate, and on the adhesive surface of plastic plate
It coats EVA modified layer or weather-proof resin layer carries out lamination treatment, so that composite panel of plastic material is obtained, but when composite panel of plastic material passes through
Prolonged use is crossed, plastic plate adhesive layer is easy to cause to crack, impact resistance is low, to influence the use year of composite plate
Limit；
Existing plastics, as main material, have a single function frequently with single high molecular polymer, and comprehensive performance is poor, cause
The mechanical strength of composite panel of plastic material is low.

Out, PET plastic clast is obtained；
Step 3: PET plastic clast obtained in step 2 is imported into drying box, is stirred drying；
Step 4: by PET plastic clast obtained in step 3 and epoxy resin, EVA, glass fibre, bismuth selenide laminar nano
Material, selenizing zirconium stratified nano materials, curing niobium stratified nano materials, silicon nanowires, silver nanowires are transported in mixer
Pressurization mixing is carried out, the mixture obtained after mixing is plasticized ripe material by extruder under the conditions of 160~190 DEG C and is passed through
Extruder is modified to be squeezed out, and the first plastic plies material is obtained；
Step 5: by PET plastic clast obtained in step 3 and fluorine resin, EVA, glass fibre, bismuth selenide laminar nano
Material, selenizing zirconium stratified nano materials, curing niobium stratified nano materials, silicon nanowires, silver nanowires be transported to another it is close
Pressurization mixing is carried out in mill, and the mixture obtained after mixing is plasticized under the conditions of 160~190 DEG C by another extruder
Ripe material is simultaneously squeezed out by the way that extruder is modified, obtains the second plastic plies material；
Step 6: steel net pad is put into mold in advance, then the thick shape plastics squeezed out in step 4 and step 5 are squeezed into
In mold, it is allowed to complete to merge by squeezing, then move into cooling device, cooling and shaping, to obtain by the first plastic plies, steel
The composite board that silk screen bed course and the second plastic plies are constituted.
