Description
Technical field
The invention belongs to weather strip for automobile field, relate to a kind of sealing strip on outer side of car window and preparation method thereof.
Background technology
Along with improving constantly of the national economic development, business prosperity and living standards of the people, automobile quantity increases day by day.The lightweight of automobile is increasingly paid attention to by each big automotive giant.The sealing property of motor-vehicle glass window is one of important document affecting car mass.Sealing strip can ensure that the sealing between glass pane and the structural member of vehicle so that is possible to prevent the environmental effect such as rainwater, dust and/or wind to enter vehicle interior.Sealing strip especially for glass of movable window has some special requirements, these windows whether can fairly linearly (horizontal or vertical) mobile, the most collapsible or can non-linearly move (the most rotatable).These requirements include high resiliency and the life-span of sealing member, the presentation quality of sealing strip and the obvious stability about environmental effect.Currently used motor-vehicle glass window sealing strip, all using metal as skeleton, because metal hardness is high, can meet requirement, but metal is heavier, so can increase the weight of automobile, and the preparation process of metallic framework is more complicated.
In order to solve the problems referred to above, applicant of the present invention discloses a kind of sealing strip on outer side of car window in the patent of Application No. CN201110327255.5, described sealing strip includes skeleton and matrix, described skeleton is chliorinated polyvinyl chloride, its outward appearance is strip, and its section is in being similar to reverse U-shaped structure；Described reverse U-shaped structure is divided into top and the first sidepiece near glass for vehicle window and the second sidepiece away from glass for vehicle window；Described matrix is polrvinyl chloride, and described matrix is coated on around described skeleton, and is provided with the first projection on the outside matrix of the first sidepiece, and the described first protruding side contacted with glass for vehicle window is provided with flannelette；The inner base of described first sidepiece and door panel contact position are provided with burr.This patent solves vehicle weight and the problem of preparation process complexity, but its impact resistance is poor.
Summary of the invention
The present invention solves the impact resistance difference technical problem of existing window sealing strip, it is provided that window sealing strip that a kind of impact resistance is good and preparation method thereof.
The invention provides a kind of sealing strip on outer side of car window, described sealing strip includes skeleton and matrix, described skeleton is the alloy plastic of chliorinated polyvinyl chloride and acrylonitrile-butadiene-styrene copolymer, and its outward appearance is strip, and its section is in being similar to reverse U-shaped structure；Described reverse U-shaped structure is divided into top and the first sidepiece near glass for vehicle window and the second sidepiece away from glass for vehicle window；Described matrix is polrvinyl chloride, and described matrix is coated on around described skeleton, and is provided with the first projection on the outside matrix of the first sidepiece, and the described first protruding side contacted with glass for vehicle window is provided with flannelette；The inner base of described first sidepiece and door panel contact position are provided with burr.
Present invention also offers the preparation method of a kind of window sealing strip, the method is the alloy plastic and polrvinyl chloride compound extrusion moulding formed with acrylonitrile-butadiene-styrene copolymer by chliorinated polyvinyl chloride, wherein said polrvinyl chloride is coated with the alloy plastic that chliorinated polyvinyl chloride is formed with acrylonitrile-butadiene-styrene copolymer completely, then flannelette is pasted onto the first protruding side contacted with glass for vehicle window, high temperature by flannelette bottom glue melt bonding with the soft-sided of PVC base system, it is fully cured stickup after the sizing of overboard stock mould and the cooling in water.
The sealing strip of the present invention is by the compound extruded of the alloy plastic skeleton of the chliorinated polyvinyl chloride of high rigidity and acrylonitrile-butadiene-styrene copolymer with the plastic material of PVC matrix, it is ensured that product while satisfied assembling, difficult drop-off, it is ensured that intensity.Replace steel band as skeleton with the alloy plastic of chliorinated polyvinyl chloride and acrylonitrile-butadiene-styrene copolymer, not only like CPVC the most lightweight (weight of CPVC is the 1/5 of steel), substantially increase the lightweight of automobile.And also the same with CPVC it is resistant to most acid, alkali, salt, there are good chemical resistance, heat-resisting aspect to be also significantly better than other plastics, all significantly improve using temperature (higher 35-40 than polyvinyl chloride resin), intensity, the performance such as heat-resisting, fire-retardant.Owing to CPVC processing temperature is higher and scope is narrower, the tendency of the HCL that thermal decomposition is released increases, and the highest and CPVC self the impact strength of the requirement to former and material molding technology is poor.And ABS mixes generation concurrent mixture as a kind of anti-impact modifier with CPVC, the impact strength of CPVC can be improved, improve its elongation at break, reduce its melt viscosity and Vicat softening point, improve its toughness.ABS resin can also effectively reduce the counter balance torque of CPVC/ABS alloy, improves the mobility of co-mixing system, makes concurrent mixture be more easy to plasticizing, thus improves the processing characteristics of CPVC.In terms of processing identical with PVC product processing mode, only need to change some processing conditionss on processing equipment can process, and more important advantage is the reduction of operation, improves efficiency.
