Abstract
The invention discloses a kind of preparation method improving glass fiber reinforced plastic shapes surface roughness, it relates to glass fiber reinforced plastic shapes technical field.Its step is as follows: pultrusion epoxy resin 48 50% and firming agent 50 52%, stirs under room temperature；The material prepared is put into hopper, glass fiber yarn through hopper；The glass fiber yarn of dipped resin is penetrated preformed board, then passes through mould；Outside the glass fiber yarn of preliminary sizing, add release cloth, then pass through mould；Set three sections of temperature as 140 ± 5 DEG C, 150 ± 5 DEG C, 160 ± 5 DEG C, set fixing speed as 20 40 cm per minute, the most normally produce, when the product of molding is after mould, release cloth is torn, it is possible to obtain the product that roughness is up to standard；Product is cut, it is thus achieved that finished product.Present invention have the beneficial effect that it utilizes the high temperature resistant of release cloth and rough surface directly forms the rough surface of product, it is to avoid time-consuming take electricity and the artificial blasting craft of expense, improve work efficiency, cost-effective.
Description
Technical field
The present invention relates to glass fiber reinforced plastic shapes technical field, be specifically related to a kind of system improving glass fiber reinforced plastic shapes surface roughness
Preparation Method.
Background technology
In prior art, the preparation flow of glass fiber reinforced plastic shapes is as follows: raw material → pultrusion die → product → cut →
Sandblasting → formation rough surface finished product, such production procedure needs the blasting craft that the expense that wastes time and energy is electric, inefficiency, system
Cause high.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of reasonable in design, improve glass
The preparation method of steel profile surface roughness, it is not in the case of increasing artificial and electric power, utilize the high temperature resistant of release cloth with
Rough surface directly forms the rough surface of product, thus avoids time-consuming expense electricity and take artificial blasting craft, is greatly improved work
Make efficiency, cost-effective.
In order to solve the problem existing for background technology, the technical solution used in the present invention is: its process flow steps
As follows:
(1) dispensing: stir under pultrusion epoxy resin 48-50% and firming agent 50-52%, room temperature；
(2) entry: the material prepared is put into hopper, glass fiber yarn through hopper, allow resin sized glass fibres yarn；
(3) preforming: the glass fiber yarn of dipped resin is penetrated preformed board, then passes through mould；
(4) release cloth is added: outside the glass fiber yarn of preliminary sizing, add release cloth, fully wrapped around glass fiber yarn,
Then pass through mould；
(5) molding: set three sections of temperature as 140 ± 5 DEG C, 150 ± 5 DEG C, 160 ± 5 DEG C, set fixing speed as 20-40
Cm per minute, the most normally produces, and when the product of molding is after mould, release cloth is torn, it is possible to obtain thick
The product that rugosity is up to standard；
(6) cut: product is cut, it is thus achieved that finished product.
Present invention have the beneficial effect that it is not increasing manually and in the case of electric power, utilize the high temperature resistant and thick of release cloth
Rough surface directly forms the rough surface of product, thus avoids time-consuming expense electricity and take artificial blasting craft, is greatly improved work
Efficiency, cost-effective.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with detailed description of the invention, right
The present invention is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
This detailed description of the invention adopts the following technical scheme that its process flow steps is as follows:
(1) dispensing: stir under pultrusion epoxy resin 50% and firming agent 50%, room temperature；
(2) entry: the material prepared is put into hopper, glass fiber yarn through hopper, allow resin sized glass fibres yarn；
(3) preforming: the glass fiber yarn of dipped resin is penetrated preformed board, then passes through mould；
(4) release cloth is added: outside the glass fiber yarn of preliminary sizing, add release cloth, fully wrapped around glass fiber yarn,
Then pass through mould；
(5) molding: set three sections of temperature as 140 DEG C, 150 DEG C, 160 DEG C, sets fixing speed as 20 cm per minute,
Normally produce under the conditions of this, when the product of molding is after mould, release cloth is torn, it is possible to obtain the product that roughness is up to standard
Product；
(6) cut: product is cut, it is thus achieved that finished product.
Through test, can successfully produce the flat board of 100X3mm specification in this way, roughness is fully achieved sticks with paste into hands
The adhesive strength requirement that type matches.
This detailed description of the invention is not increasing manually and in the case of electric power, utilizes the high temperature resistant of release cloth and rough surface
Directly form the rough surface of product, thus avoid time-consuming expense electricity and take artificial blasting craft, be greatly improved work efficiency, joint
Cost-saving.
The above, only in order to technical scheme to be described and unrestricted, those of ordinary skill in the art are to this
Other amendment or equivalent that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
All should contain in the middle of scope of the presently claimed invention.
