Description
Technical field
2. the invention discloses a kind of wear-resisting flat organic glass, belong to technical field of polymer materials.
Background technology
4. lucite is a kind of popular title, PMMA is abbreviated as.The chemical name of this macromolecule transparent material is poly- methyl
Methyl acrylate, it is the high-molecular compound formed by methyl methacrylate polymerization.It is a kind of exploitation important thermoplastic earlier
Property plastics.The preparation method of lucite has（1）Mounting method：After lucite is cut into definite shape, paste in the plane
Form；（2）Pressure sintering：After lucite thin plate heating, middle hot pressing type in a mold；Hot-die can use timber, greasy filth moulding,
Then matched molds are made with casting lead, gypsum material, can be molded after lucite heating；（3）Inlaying process：By having for different color
Machine glass blocks cuts into the geometric figure taken out and needed, and mosaic splicing forms on bottom plate；（4）Vertical Mill method is by rod lucite or thickness
After plate shape lucite bonding, directly ground on emery wheel, polish shaping；（5）Disconnected mill method：By the overlapping stickup of plate shape lucite
Together, then direct skiving section shaping；（6）Fire bending method：Lucite is worked into definite shape, by lucite plus
Heat, directly it is molded with the rapid nest system of hand, kneading.Above several method is used interchangeably, and is required according to the art of shape-designing, fixed
The best approach
5. translucency is optimal in the plastic for lucite, more than 92% sunshine can pass through, ultraviolet is up to 73.5%；And have
Good weatherability, resistance to acids and bases, dimensional stability, insulating properties and good thermoplastic processability etc., easily processed into type, quilt
It is widely used in building, culture and education, navigation, aviation and daily life etc..But there is also heat resistance, resistance to for lucite
Mill property, toughness is poor, organic solvent resistance is poor, water absorption rate is higher, it is easy scratch, be also easy to produce the shortcomings of crazing.Traditional organic glass
Glass toughening modifying method mainly has:（1）Copolymerization, crosslinking toughness reinforcing；（2）Mix second phase particles blending toughening；（3）Gathered using IPN
Polymeric network structure；（4）Using biaxial oriented stretch and MULTILAYER COMPOSITE technique；（5）Fiber reinforcement technology.
PMMA is typical unformed high polymer material, and the most effectual way for improving its heat resistance is macromolecular chain segment is lived
Dynamic property reduces.According to this principle, on the premise of the original performance of lucite, the particularly transparency is kept, the organic glass of tradition
Glass introduces bulky group by using on PMMA main chains, and cyclic structure is introduced on PMMA main chains and adds crosslinking agent etc.
Method carries out improving its heat resistance.
Therefore, improve lucite anti-wear performance, heat resistance, toughness and mechanical property, turn into lucite large area
Promote the use of urgent problem to be solved.
