Abstract
The invention relates to a special thin sealing film for an automobile door. The special thin sealing film consists of the following compositions in weight portion: 65 to 85 portions of polythene, 8 to 12 portions of a flame retardant and 22 to 28 portions of high-density polyethylene. The compositions have the optimal mixture ratio in weight portion: 75 portions of the polythene, 10 portions of the flame retardant and 25 portions of the high-density polyethylene. The thin sealing film has the advantages that the special thin sealing film for the automobile door does not deform basically at the high temperature of 150 DEG C and does not crack at the temperature of 40 DEG C below zero; and the flame retardance of the special thin sealing film can reach the level of less than or equal to 60 mm/min. An automobile door sealing piece manufactured by the special thin sealing film for the automobile door has the functions of flame retardance, water and dust prevention and sound isolation. The special thin sealing film can be also used as a heat insulation and preservation material in a train, a passenger car, a steamboat, a building, an agricultural greenhouse and other fields.
Description
Technical field
The present invention relates to the Chemicals field.Relate in particular to sealing film special for vehicle door polyethylene.
Background technology
Present existing automobile door sealing material film processes for the common polythene plastics film, and its weak point is its function singleness, does not have high temperature resistant and anti-flaming function.
Summary of the invention
The present invention is directed to existing automobile door sealing material common polythene film, function singleness does not have the deficiency of the high temperature resistant and anti-flaming function of automotive field requirement, and a kind of sealing film special for vehicle door polyethylene of high temperature resistant and anti-flaming function is provided.
Be made up of polyethylene, fire retardant, high density polyethylene(HDPE), its weight part proportioning is:
Polyethylene 65-85 fire retardant 8-12 high density polyethylene(HDPE) 22-28.
Optimum weight part proportioning is:
Polyethylene 75 fire retardants 10 high density polyethylene(HDPE)s 25.
Advantage of the present invention is: it is indeformable substantially that the vehicle door polyethylene film special is met 150 ℃ of high temperature, meets-40 ℃ of not embrittlement, fire-retardant Ke Da ≦ 60mm/min rank.That the door sealing spare that is made by the vehicle door polyethylene film special possesses is fire-retardant, waterproof and dustproof, sound damping function.The heat-insulation and heat-preservation material that also can be used as fields such as train, passenger vehicle, steamer, building, agricultural greenhouse.
Embodiment
Complete processing of the present invention is with existing conventional film plastic moulding process, with polyethylene is 75 parts of base-materials, 10 parts of fire retardants (magnesium hydroxide or zinc borate), 25 parts of batch mixes of high density polyethylene(HDPE) (5000S), through the blow molding of conventional inflation film manufacturing machine group, thickness is the smooth film of translucent any surface finish of 0.05-0.30mm.
Claims (2)
1, sealing film special for vehicle door polyethylene is characterized in that it is made up of polyethylene, fire retardant, high density polyethylene(HDPE), and its weight part proportioning is:
Polyethylene 65-85 fire retardant 8-12 high density polyethylene(HDPE) 22-28.
2, sealing film special for vehicle door polyethylene according to claim 1 is characterized in that its weight part proportioning is:
Polyethylene 75 fire retardants 10 high density polyethylene(HDPE)s 25.
