Abstract
The invention relates to a production process of a PVC (polyvinyl chloride) calendered film. The production process comprises the following steps that: (1) firstly, the calendered film from a bottom roller of a calendering almost synchronously passes through a first group of guide leaving rollers with a normal temperature water channel and a second group of guide leaving rollers with a hot oil channel and a third group of guide leaving rollers; (2) then, the calendered film passes through a knurling roller with a hot water channel, and the knurling roller and a rubber roller work together to knurl the calendered film; (3) multiple groups of cooling rollers are used for cooling and shaping the calendered film; and (4) finally, carrying out side shearing and rolling. Compared with the prior art, the production process provided by the invention has the advantages that the temperature difference between the bottom roller of the calendered and the guide leaving rollers and among the guide leaving rollers through the normal temperature water channel arranged in the first group of guide leaving rollers, the calendered film passes through the guide leaving rollers almost synchronously, the condition that molten material is stretched so as to generate water ripples is effectively prevented, and people can not see the water ripples of the calendered film in a light transmitting condition.
Description
Technical field
The present invention relates to the raw-material calendered film of a kind of lampshade, particularly a kind of production technology of PVC calendered film.
Background technology
The existing PVC calendered film that is used for doing lampshade, its technological process is mainly as follows: calendered film from calender out after, many groups doff roll through being provided with the deep fat passage is plasticizing and stable further, the velocity of rotation of many group doff rolls differs larger, enter the knurling rolls that are provided with the chilled water passage and carry out embossing molding, then cooled transition, enter trimming and central coiling, the PVC calendered film printing opacity that above-mentioned technique is made sees that water ripples are serious, the lampshade of making of this material affects outward appearance, need to paste nonwoven and hide, indirectly increased the manufacturing cost of lampshade.
Summary of the invention
The present invention is intended to solve the defects of prior art, provides a kind of calendered film that makes without the production technology of the PVC calendered film of water ripples.
The technical solution adopted in the present invention is: a kind of production technology of PVC calendered film comprises the following steps:
1) at first allow from calender bottom roller calendered film out through first group of doff roll being provided with the normal-temperature water passage and be provided with second group of doff roll of deep fat passage, the 3rd group of doff roll, calendered film with near synchronous speed by aforementioned three groups of doff rolls;
2) then allow calendered film by being provided with hot water channel's knurling rolls, knurling rolls coordinate with rubber rollers calendered film are carried out embossing molding;
3) then by many groups chill roll, calendered film is carried out cooling and shaping
4) carry out at last trimming and batching.
Described knurling rolls are mute sand roller.
Described calendered film is be controlled between 1.1～1.9 the draw ratio of calendered film near synchronous speed by aforementioned three groups of doff rolls.
The temperature of described calender bottom roller is controlled between 160～180 ℃.
The doff roll temperature of described second and third group is controlled between 160～165 ℃.
Described knurling rolls temperature is controlled between 80～95 ℃.
Chill roll is three groups, and the temperature of three groups of chill rolls is staged and reduces.
The temperature of first group of chill roll is arranged between 75～85 ℃.
The temperature of second group of chill roll is arranged between 70～80 ℃.
The temperature of the 3rd group of chill roll is arranged between 65～70 ℃.
Compared with prior art, the present invention is by being provided with the normal-temperature water passage at first group of doff roll, increase the temperature difference between calender bottom roller and doff roll and doff roll and doff roll, to pass through doff roll near synchronous speed, have the following advantages: the material that 1) effectively prevents melting produces water ripples because of stretching, and assurance calendered film printing opacity is seen without water ripples; 2) the mute degree in bottom surface and face line approach, be two-sided frosted finish effect, and printing opacity is seen without water ripples, impurity, brilliant point, can't see spot light, light scattering is even, reach the requirement of lampshade material, 3) need not paste nonwoven and can directly print on the PVC calendered film, save the lampshade material cost and also save PVC calendered film and non-woven fabric compounded processing cost and loss simultaneously.
The specific embodiment
A kind of production technology of PVC calendered film comprises the following steps:
1) at first allow from calender bottom roller calendered film out through first group of doff roll being provided with the normal-temperature water passage and be provided with second group of doff roll of deep fat passage, the 3rd group of doff roll, calendered film with near synchronous speed by aforementioned three groups of doff rolls; Be provided with the normal-temperature water passage at first group of doff roll, the temperature difference between increase calender bottom roller and doff roll and doff roll and doff roll is conducive to calendered film and peels off out from the calender bottom roller rapidly, reduce draw ratio, described draw ratio is controlled between 1.1～1.9, the material that effectively prevents melting produces water ripples because of stretching, and assurance product printing opacity is seen without water ripples; The temperature of calender bottom roller is controlled between 160～180 ℃, and the doff roll temperature of second and third group is controlled between 160～165 ℃.
2) then allow calendered film by being provided with hot water channel's knurling rolls, knurling rolls coordinate with rubber rollers calendered film are carried out embossing molding; Described knurling rolls are mute sand roller, and the PVC calendered film after embossing molding is two-sided frosted finish effect; The knurling rolls temperature is controlled between 80～95 ℃.
3) then by many groups chill roll, calendered film is carried out cooling and shaping, chill roll is three groups, and the temperature of three groups of chill rolls is staged and reduces, and helps further to eliminate the flaws such as straight line line of cold drawn generation.The temperature of first group of chill roll is arranged between 75～85 ℃, and the temperature of second group of chill roll is arranged between 70～80 ℃, and the temperature of the 3rd group of chill roll is arranged between 65～70 ℃.
4) carry out at last trimming and batching.
According to the calendering PVC calendered film that production technology of the present invention is produced, the mute degree in bottom surface and face line approach, and are two-sided frosted finish effect, and printing opacity sees without water ripples, impurity, brilliant point, and can't see spot light, light scattering is even, reaches the requirement of lampshade material.
