Abstract
The invention relates to a manufacturing method of a thermoplastic polyester elastomer conveyer belt with low shrinkage and deformation. A thermoplastic polyester elastomer (TPEE) is coated on a fabric. The manufacturing method comprises the following steps of: blending the thermoplastic polyester elastomer and a polyolefin nucleating agent according to the ratio of 500: (0.5-1.5) in parts by weight by using a blender to obtain a blend; extruding and granulating the blend by a twin screw extruder to obtain grains; freezing the grains at a low temperature, crushing the grains into powder; thermally shaping the fabric; coating the powder on the fabric, putting the fabric in an oven at 160-180 DEG C to be processed for 2-5min, cooling and shaping to obtain the product. The invention has the advantages that the TPEE is uniformly crystallized by blending the nucleating agent and the TPEE, the smoothness of the conveyer belt can be ensured when the thickness is small, the original performances of the TPEE are not influenced by the use of the nucleating agent, and unfavorable influence on other performances of the conveyer belt can not be caused while the smoothness of the conveyer belt is ensured.
Description
Technical field
Conveyer belt manufacturing of the present invention relates in particular to a kind of manufacture method of thermoplastic polyester elastomer conveyer belt with low shrinkage and deformation.
Background technology
Thermoplastic polyester elastomer (TPEE) is the block copolymer that contains hard section of polyester and polyester soft segment.Wherein polyester soft segment and uncrystallized polyester form the hard section of amorphous phase polyester partially crystallizable and form the crystallization microcell, play physical crosslinking point.TPEE has the elasticity of rubber and the intensity of engineering plastics; Giving its elasticity for soft section makes it as rubber; Hard section is given its processing characteristics, makes it resemble plastics; With the rubber phase ratio, it has better processability energy and longer service life; Compare with general plastics, have advantages of high strength equally, and pliability and dynamic mechanical are better.
But TPEE is in process, because grain size and skewness cause it that bigger contraction distortion is arranged in the crystallisation by cooling process.And in the manufacture process of conveyer belt,, can cause the conveyor belt surface out-of-flatness because it has big contraction distortion, both sides upwarp, and shown in the TPEE conveyer belt picture that Fig. 1 traditional approach is produced, the outward appearance and the serviceability of conveyer belt are caused bigger influence.Usually solve this problem by the thickening surface material, and with the other materials MULTILAYER COMPOSITE, but can cause the rising of cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of easy low shrinkage and deformation TPEE conveyer belt manufacture method.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of manufacture method of thermoplastic polyester elastomer conveyer belt with low shrinkage and deformation, thermoplastic polyester elastomer are coated on the fabric, in regular turn by following step manufacturing:
The first step: with blender with thermoplastic polyester elastomer and polyolefin nucleating agent by weight with 500: the ratio blend of (0.5～1.5) obtains blend composition;
Second step: blend composition by double-screw extruding pelletizing, is obtained pellet;
The 3rd step: pellet is carried out cryogenic freezing, be ground into the powder material;
The 4th step: fabric is carried out HEAT SETTING handle;
The 5th step: the powder material is coated on the fabric, enters 160 ℃～180 ℃ baking ovens, be 2～5min process time, and cooling and shaping makes finished product.
On the such scheme basis, described polyolefin nucleating agent is 1,3:2, two pairs of methyl benzals of 4-sorbierite.
On the such scheme basis, in the 3rd step, the temperature that described cryogenic freezing is pulverized is-35 ℃～-45 ℃.
The present invention improves traditional TPEE material, makes it form uniform crystal region in process.
The invention has the beneficial effects as follows:
1, owing to adopted nucleator and TPEE blend, makes the TPEE crystallization even, when thinner thickness, also can guarantee the smooth of conveyer belt;
2, the use of nucleator can not impact the original performance of TPEE, is guaranteeing that conveyer belt can not cause adverse influence to other performances of conveyer belt in smooth.
