Description
Technical field
The invention discloses a kind of preparation method of doors and windows sealing strip material, belong to sealing strip preparing technical field.
Background technology
Door and window sealing strip is mainly used in the building decoration door and window such as plastic-steel door and window, aluminum alloy doors and windows, Wood-door window.In the market
Plastic-steel door and window sealing strip is generally by PVC, modified PVC, EPDM, elastic body sealing strip（Including TPV, TPE, TPR, SEBS）、
The materials such as silica gel are extruded into.
Door and window sealing strip is divided into glazing tape, door leaf door pocket sealing strip and wool top three major types, glass capsulation in purposes
Bar is used for the sealing between glass and fan and frame, and door leaf door pocket sealing strip is mainly used for the sealing between door-plate and doorframe, wool top
The sealing being mainly used between frame and fan.In plastic-steel door and window and bridge cut-off aluminium door and window, timber production and installation, sealing strip is a kind of
Essential annex.
Sealing joint strip plays waterproof, sealing and energy saving important work in plastic-steel door and window and bridge cut-off aluminium door and window and Wood-door window
With, sound insulation, dust-proof, antifreeze, warming.It must have very strong tensile strength, good elasticity, it is also necessary to relatively good heatproof
Property and resistance to ag(e)ing.In order to ensure the fastening of adhesive tape and section bar, the section structure size of adhesive tape must be with plastics-steel shapes for door and window
Match somebody with somebody.Sealing joint strip is generally used for horizontally-opening windows and doors, hangs on window, Foldable door and window.Main function is dust-proof, insect prevention, waterproof, sound insulation, close
Envelope etc..
The actual key of door and window is to seal, and seals fine or not sealing strip and plays very important effect.Sealing on the market
Bar material is usually what PVC was modified, its key effect is exactly that the good of plasticizer is added inside it nothing but in flexible PVC
It is bad, constantly raise up with the price of various petrochemicals, the rubber such as sealing strip price is also constantly being lifted.Some are not
Short-term interests is only seen by responsible producer, has started the illegitimate competition in terms of raw material, has been brought very to consumers in general
Big hidden danger.In door manufacturing process, the input accounting weight very little of sealing strip, but its very important, door and window sealing strip of effect
Quality identification method includes following several：There is surface permeability precipitation phenomenon, those used oil are basic and PVC is not and molten, sealing
Bar surface is easy to grease occur, and the trace of yellow is also caught in Surface of profile.Even not environmentally there are many volatile substances, pollute
Air.After those so-called plasticizer volatilizations or exudation, sealing strip will lose its original flexibility, become very hard,
And aging is shunk quickly, there is very big gap in the closed part of such door and window, and seal becomes very poor（Leak, leaks dirt）
Steel lining especially inside plastic-steel door and window can be corroded quickly, have many consumers and be frequently found in rainy season from the press strip portion inside window
The liquid that bit stream goes out many red is very dirty, that is, door and window leak steel lining is corroded too early, and the service life of door and window can greatly reduce.
But now rice stick the most common are topic be exactly the poor flexibility in low temperature the defects of.Therefore, invention is a kind of at low ambient temperatures
The good sealing strip material of elasticity has positive effect to sealing strip preparing technical field.

Any catalyst is wanted, obtained maleic rosin adds the degree of functionality of molecule, thus with spies such as higher softening point, acid numbers
Point, secondly, maleic rosin belong to polyesterification reaction, can be dropped by esterification with glycerine reaction generation modified rosin resin, its reaction
The acid number of low maleic rosin, improves its softening point, and improves its stability, the raising of softening point, uses spray peroxide sulphur
Change glue, be crosslinked, the coefficient of cubical expansion of peroxide cure glue, which compares conventional sulfur-cured vulcanizate, greatly segment can be made movable
Free space increase, be conducive to glass transition temperature reduction, in addition, during peroxide cure, form firm, short and small-C-
C- cross-bonds, and during with Sulfur vitrification, then can form that firmness is smaller, the larger polysulfide bond of length, therefore window sealing strip material
When deforming upon, the intermolecular force to be overcome can bigger one this, while weak bond is distorted, and which adds hysteresis
Loss, increases creep rate, and deformation contracting property improves, so that viscoplasticity increase is obtained during window sealing strip material low temperature, should
With having a extensive future.
