Abstract
The invention relates to new materials, in particular to a sheet molding compound, and aims to provide a high-performance sheet molding compound which is simple in formulation. The high-performance sheet molding compound is composed of, by weight, 80 parts of unsaturated polyester resin, 23 parts of polystyrene, 17 parts of polymethyl methacrylate, 85 parts of porous powder quartz, 120 parts of long glass fiber, 6.5 parts of barium stearate, 3 parts of tert-butyl perobenzoate, 2.5 parts of N-phenyl maleimide, 4.5 parts of vinyl distearamide, 2.5 parts of molybdenum disulfide and 2 parts of calcium oxide. The high-performance sheet molding compound (SMC) has excellent physical performance index. High structural strength of a plastic product made of the SMC is guaranteed, weight of the plastic product is lowered greatly, and material cost is reduced remarkably.
Description
Technical field
The present invention relates to new material, be specifically related to a kind of sheet molding compound.
Background technology
SMC is the abbreviation of Sheet molding compound, i.e. sheet molding compound.The most former
Expect by SMC special yarn, unsaturated-resin, low shrinkage additive, filler and various auxiliary agent composition.
It primarily occur ins Europe in earlier 1960s, about nineteen sixty-five, and beautiful, day phase
Secondary has opened up this technique.China, the end of the eighties, has introduced the SMC production line of external advanced person
And production technology.SMC has superior electric property, decay resistance, light weight and engineering design
Easily, the advantage such as flexibly, its mechanical performance can compare favourably with part metals material, thus extensively
It is applied in the industries such as haulage vehicle, building, electronic/electrical gas.
These advantages based on sheet molding compound, field such as municipal administration rainwater treatment etc. makes the most more and more
Use laminar film plastic.But because the physical properties such as sheet molding compound structural strength are the highest, so
As when being embedded into the products such as the tank of underground, pipeline, the thickness of product is thicker, on the one hand
The heaviest, the most also waste processing cost.
Summary of the invention
It is an object of the invention to provide a kind of simple high-performance sheet molding compound of filling a prescription.
For achieving the above object, the technical solution adopted in the present invention is: a kind of high-performance sheet
Shape moulding compound, is made up of following weight portion: unsaturated polyester resin 80 parts, polystyrene 23 parts,
Polymethyl methacrylate 17 parts, 85 parts of periporate quartz, roving glass fiber 120 parts, barium stearate
6.5 parts, peroxidized t-butyl perbenzoate 3 parts, N-phenylmaleimide 2.5 parts, vinyl
Double stearic amides 4.5 parts, molybdenum bisuphide 2.5 parts, 2 parts of calcium oxide.
Preferably, described SMC material is processed into by the following method:
A. by described weight portion by polystyrene, polymethyl methacrylate, perbenzoic acid uncle
The double stearic amide of butyl ester, N-phenylmaleimide, vinyl and molybdenum bisuphide join not
In saturated polyester resin, mix；It is subsequently adding periporate quartz, barium stearate and calcium oxide
Powder, mixes, and obtains resin paste.
B. step a gained resin paste is coated on upper and lower two layers of polyethylene film uniformly, in
Between uniform settlement through silane coupler process after roving glass fiber, through extruding, make resin paste and long glass
Rolling after fine fully infiltration；
C. sheet material step b wound, thickening more than 45 hours at 35-45 DEG C.
The method have the advantages that the SMC material of the present invention, its physical performance index is excellent
Different.The plastic product being made up of the SMC material of the present invention is ensureing on the premise of high structural strength it
Weight will greatly reduce, and material cost substantially reduces.
Detailed description of the invention
The present invention provides the engineering plastics that can be used for making the plastic products such as Plastic Drum, plastic well.
