Abstract
A disclosed rubber strip is characterized by being composed of the following compositions in parts by weight: 20-30 parts of hydrogenated styrene resin, 15-30 parts of calcium carbonate, 15-30 parts of polypropylene, 10-12 parts of a maleic anhydride grafted polymer, and 5-10 parts of UV-P. The above compositions are mixed at 80 DEG C for 8 min according to the ratio, so that a mixed material is obtained, and then the above mixed material is subjected to extruder mixing, granulation and packaging, so that a product is obtained. The rubber strip is good in welding strength and good in weatherability.
Description
Technical field
The present invention relates to a kind of rubber item, particularly relate to a kind of India-rubber strip.
Background technology
India-rubber strip only just can play sealing function under elastic prerequisite, so various India-rubber strip product all continues to use whippy elastomeric material for a long time.There is painted difficulty in the elastomeric material of the first-generation, manufacturing procedure is complicated, and expendable defect.Very fast elastomeric material is just replaced by s-generation PVC sealing material, PVC sealing material have low price, production technique simple, can the advantage such as high-efficiency and continuous production.But along with the requirement that human consumer is more and more higher to quality, the feature of environmental protection of PVC India-rubber strip, and the hazardous property of the PVC India-rubber strip course of processing, in use procedure, the defect such as lower temperature resistance difference is exaggerated.So thermoplastic elastic material becomes a developing direction of rubber strip material, but thermoplastic elastic material, in welding strength, weathering resistance, need to improve at present.
Summary of the invention
Technical problem to be solved by this invention is: provide the India-rubber strip that a kind of welding strength is good, weather resistance is good.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of India-rubber strip, is made up of the component calculated by weight as follows:
Hydrogenated styrene resin 20 ~ 30 parts;
15 ~ 30 parts, calcium carbonate;
Polypropylene 15 ~ 30 parts;
Maleic anhydride grafts 10 ~ 12 parts;
UV-P 5 ~ 10 parts.
Compared with prior art, the beneficial effect that the present invention has is:
(1) halogen-free material in constitutive material of the present invention, without the o-benzene plasticiser of harmful health of human body, have lightweight, rebound resilience is high, welding strength good, be easy to colouring, lower temperature resistance is good, the advantages such as environmental protection;
(2) the present invention is by acrylic resin kind with quantifier elimination, matches the UV-P weather resisting agent good with Miscibility, greatly can improve the weather resistance of product;
(3), when using rubber strip material of the present invention to carry out extrusion moulding, do not need through high temperature vulcanized, extrusion does not have toxic gas to decompose, and can not corrode production unit, and scrap stock can be recycled.
Embodiment
Below in conjunction with embodiment, the present invention is further detailed explanation.
