Description
Technical field
The present invention relates to a kind of incubator, particularly a kind of incubator shell and its manufacture method.
Background technology
Plastic Foam Box is made by being filled in as the polyurathamc of insulation material in polyethylene sheath.Because of incubator
Volume is larger, and polyethylene sheath is frequently with rotation molding, but rotation molding can cause shell inside and outside both side surface flat smooth, and
Because polyurethane is polar material, polyethylene is non-polar material, thus polyurathamc is not strong to the adhesive force of polyethylene, is held
Incubator finished product delamination is easily caused, i.e. polyethylene sheath separates with the polyurathamc of filling.
Plastic Foam Box shell of the prior art is in order to solve delamination problems, after polyethylene sheath rotation molding and still
When uncolled, to the interior side spray LLDPE little particle of polyethylene sheath, thus obtained incubator housing exterior
Face still flat smooth, and inner side becomes coarse because LLDPE little particle is fixed with, to a certain extent
Polyurathamc is increased to the adhesive force on the inside of polyethylene sheath.But this method has the disadvantages that：（1）, the amount dusted compared with
Greatly, dusting operation can not realize the lightweight of product to weightening more than 30% outside turnout.（2）, add the process dusted,
Secondary batching, reduce production efficiency.（3）, be difficult to ensure that in dusting operation and dust uniformly, dust it is excessive and it is very few all can be unfavorable
Polyethylene sheath is clinged in polyurathamc.（4）, using dusting change manufactured insulation after roughness on the inside of polyethylene sheath
Case, polyurathamc be not still high to adhesive force on the inside of polyethylene sheath, and delamination is still present, and product disqualification rate is high.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of smooth in appearance and inner side is coarse, and manufacturing step letter
Single, reduction product weightening, the coarse resist delamination incubator shell being evenly distributed and its manufacture method.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of resist delamination incubator shell, is made up of the raw material of following parts by weight：100 parts of substrate resin, the reinforcing agent of 35-45 mesh
0.1-0.6 parts, 4-10 mesh and glass transition temperature are not less than assisted resin 1-2 parts of the substrate resin.
The substrate resin is high density polyethylene (HDPE).
The reinforcing agent is selected from barium sulfate, calcium carbonate, one or both of sodium sulphate and two or more arbitrary proportions
Mixture.
The assisted resin is selected from one or both of PLA, makrolon, polyamide and two or more any ratios
The mixture of example.
A kind of manufacture method of described resist delamination incubator shell, this method is, by the raw material one of above-mentioned parts by weight
Secondary property is added in the rotational molding machine for installing mould, the rotational moulding 15-20min at 300-450 DEG C, and the resist delamination insulation is obtained after cooling
Case shell.
The beneficial effects of the invention are as follows：The present invention adds substrate resin, reinforcing agent and particle diameter ratio base material tree with once feeding intake
Fat is greatly and glass transition temperature is not less than the assisted resin of substrate resin, and the incubator shell inner side obtained after rotation molding is recessed
Convex injustice, roughness is big, and bumps are evenly distributed everywhere, while the surface of incubator shell is still smooth；Filling-foam gathers
It is strong with polyurathamc adhesive force after urethane；Increased weight outside turnout few, realize the lightweight of product；Shaping disposably feeds intake, and walks
Rapid simple, production efficiency is high.
Embodiment
A kind of resist delamination incubator shell, is made up of the raw material of following parts by weight：100 parts of the substrate resin of 35-45 mesh, increase
Strong agent 0.1-0.6 parts, 4-10 mesh and glass transition temperature are not less than assisted resin 1-2 parts of the substrate resin.
The substrate resin is high density polyethylene (HDPE).
The reinforcing agent is selected from barium sulfate, calcium carbonate, one or both of sodium sulphate and two or more arbitrary proportions
Mixture.
The assisted resin is selected from one or both of PLA, makrolon, polyamide and two or more any ratios
The mixture of example.
Increase explanation：In rotation molding, the small substrate resin part of particle diameter is taken the lead in, and the hot mould of contact is heated to be melted
Melt to be adhered on mould and form the smooth outer surface of incubator shell, assisted resin is because its particle diameter is bigger than substrate resin, vitrifying
Transition temperature is not less than substrate resin, thus melting is slower, uniformly mixes and is collectively forming outside incubator with remaining substrate resin
The inner side of shell, assisted resin melting is incomplete, but is fixed by substrate resin, has benefited from this, and the inner side of incubator shell is concavo-convex
Injustice, formation is millimetre-sized rugged, plus assisted resin using thermoplastic polars such as PLA, makrolon, polyamide
Resin, with being all that to contact adhesive force strong for the polyurathamc of polar material, make obtained incubator that delamination not occur.Add auxiliary
After resin, contrast and use substrate resin merely originally, mechanical property can change mends, it is necessary to add a small amount of reinforcing agent
By force.
