Abstract
The invention discloses a kind of surface modification technologies of expanded polypropylene material, are to solve the problem of Patent No. CN108340530A prepares finished product.Specific step is as follows: step 1 by the present invention, and EPP is used existing production technology, obtains EPP finished product；Step 2, according to the thickness of EPP finished product, select different method of modifying, when EPP finished product thickness is greater than 2 centimetres, melting, cooling are directly heated with surface of the another set of equipment to finished product and are formed, when EPP finished product thickness is not more than 2 centimetres, one layer of modified layer of coating, cooling are heated in EPP finished surface with another set of equipment and is formed.The shortcomings that present invention forms plastic cement (or rubber) epidermis of one layer of similar Shooting Technique effect, overcomes the easy fouling of traditional EPP foaming product surface, not wear-resisting, not withstand pressure, weather-proof difference, is not easy to secondary operation；The present invention greatly expands applicable and usage range field under conditions of giving full play to EPP superiority, and achievees the effect that it can be used repeatedly and prolong the service life.
Description
Technical field
The present invention relates to the modified field expanded polypropylene (EPP), the surface of specifically a kind of expanded polypropylene material is modified
Technique.
Background technique
Expanded polypropylene (EPP) material proportion is light, elasticity is good, antidetonation resistance to compression, Recovery is high, absorbent properties are good, resistance to
Oily, acidproof, alkaline-resisting, resistance to various chemical solvents do not absorb water, insulate, heat-resisting (- 40~130 DEG C), non-toxic and tasteless, can 100% circulation
Using and performance almost do not reduce, be real environmentally friendly foamed plastics；It can in the mold of molding machine with EPP bead
It is molded as various EPP products of different shapes.
EPP can be widely used for furniture, indoor wall, material storage packaging, compartment inner wall, Anti-collision materials etc., but practical application
In, it contacts with air or repeatedly with the contact surface of other articles because of pollution and loss after use, stitches between foam beads
Gap dust accumulation, it is difficult to clean up, influence Reusability, so need all surfaces of the EPP finished product contact surface or product into
Row is modified, and product surface can be made to become easy cleaning, be not easy to be stained；It can also be printed the surface of EPP finished product is modified
Etc. secondary operation, greatly expanded under conditions of giving full play to EPP superiority be applicable in, usage range field, and realize anti-
It is multiple to use, extend the service life.
A kind of incubator surface skining technique of patent of invention (CN108340530A), using skinning in mould after formed product
Surface preparation (also referred to as " single step mould inside skinning method "): directly after the completion of formed product, continue to shaping mould
Certain temperature makes product surface form slow melting layer, then cooling and shaping, forms surface skining, but due to the mold of its foaming
Characteristic, finished product can only do single side skinning, cannot achieve the multi-panel and all surfaces skinning of EPP finished product, and in process of production
Production is poor, and production efficiency is low.
Summary of the invention
The purpose of the present invention is to provide a kind of surface modification technologies of expanded polypropylene material, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the invention provides the following technical scheme:
A kind of surface modification technology of expanded polypropylene material, the specific steps are as follows:
EPP is used existing production technology, obtains EPP finished product by step 1；
Step 2, when the thickness of EPP finished product is greater than 2 centimetres, using from skinning method: with another set of equipment to EPP at
The surface of product directly heats melting, then carries out cooling and forming processes, and the surface of EPP finished product becomes PP material at this time,
Form one layer of epidermis that similar Shooting Technique effect is presented；
Step 3, when the thickness of EPP finished product be not more than 2 centimetres when, glue method is covered using heat: with another set of equipment EPP at
Then the material of product surface hot melt one layer of modified layer of coating, modified layer can carry out cooling and forming processes with EPP hot melt adhesion
, form plastic cement (or rubber) epidermis of one layer of similar Shooting Technique effect.
As a further solution of the present invention: whole heating or hot melt coating modified layer are carried out to the surface of EPP finished product,
Actual surface processing mode depends on product or client's specific requirement, and needs effect to be achieved.
As a further solution of the present invention: using another set of equipment to the surface of EPP finished product in step 2 and step 3
Heating or hot melt coating modified layer, using effect are good.
As a further solution of the present invention: surface heated temperature is 120-180 DEG C, when surface heated in step 2
Between be 10-25 seconds, actual temperature and heating time select according to customer demand.
As a further solution of the present invention: water cooling or air cooling, user are cooled in step 2 and step 3
The suitable type of cooling is selected according to the actual working environment of oneself, improves production efficiency.
As a further solution of the present invention: the water cooling time is 20-28 seconds, and the time of air cooling is 8-15 minutes,
Practical cooling time can be applied widely with unrestricted choice.
As a further solution of the present invention: stating modified layer in step 3 is PP material, PE material or rubber material system
Make, these three materials are easy to get, and cheap, appearance is good.
As a further solution of the present invention: surface is carried out again after forming processes the secondary operation such as to print, it is greatly rich
The rich application range of EPP.
Compared with prior art, the beneficial effects of the present invention are:
Manufacturing process of the present invention need to only change by after the completion of traditional EPP formed product, then to melt surface or hot melt coating
Property layer, cooling and shaping EPP product surface (part or all of) to be processed into mirror effect, surface become after heating PP, PE,
The plastic cement materials such as rubber, process above are also referred to as the comprehensive skinning method of two-step；
Relative to single step mould inside skinning method (such as patent of invention CN108340530A, a kind of incubator surface skining
Technique) directly after the completion of formed product, continue to give shaping mould certain temperature, so that product surface is formed slow melting layer, then cool down
Sizing forms internal skinning；The present invention can be bigger realization EPP product skinning area, can make EPP product product surface become
It obtains easy cleaning and is not easy to be stained；Also facilitate that EPP finished product skinning surfaces are modified to carry out the processing such as printing again；
The present invention is using comprehensive " the comprehensive skinning method of two-step ", under conditions of giving full play to EPP superiority greatly
Applicable and usage range field is expanded, and achievees the effect that it can be used repeatedly and prolongs the service life.
