Abstract
The invention relates to a building water supply PVC-U pipe fitting and a production method thereof. The building water supply PVC-U pipe fitting is prepared from, 100 parts of PVC resin (S-700), 2 parts of OM-710S, 3 parts of ESO, 3 parts of ACR-401, 7 parts of CPE-135A, 6 parts of CaCO3, 1.5 parts of titanium dioxide, and 0.5 part of ZB-60. The production method comprises steps of material preparation, kneading, granulation, injection moulding, finishing, and product storage. The building water supply PVC-U pipe fitting obtained via the production method possesses excellent low temperature toughness, rigidity, circular rigidity, and creep resistance; gravity deformation is not caused in long term using; product service life is prolonged; and it is beneficial for large-scale popularization.
Description
Technical field
The present invention relates to a kind of building water supply PVC-U pipe fitting and production technique thereof, belong to plastic pipe processing technique field.
Background technology
Rigid polyvinyl chloride (PVC-U) universal pipe, pipe fitting are a kind of products that Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) starts in the nineties to promote the use of, light weight, inexpensive, corrosion-resistant is had compared with galvanized steel tubing, cast iron pipe fittings, the advantages such as flow velocity is fast and easy for installation are desirable water supply pipe in building regeneration products.Within 2006, country revises former GB, and market constantly occurs novel material and auxiliary agent again; For meeting requirement and the follow-up market of new national standard GB10002.2-2003, improvement formula and adjustment production technique just seem necessary.Relative to the continuity expressing technique of PVC-U tubing, building water supply PVC-U pipe fitting adopts Shooting Technique.According to the experience being engaged in PVC processing for many years, the material choice of PVC-U pipe fitting, formulating of recipe and technology controlling and process are improved.
Summary of the invention
The object of the invention is to: for the defect of prior art, propose a kind of building water supply PVC-U pipe fitting and production technique thereof, the building water supply PVC-U pipe fitting made by this complete processing, there is low-temperature flexibility, rigidity, ring stiffness and creep resisting ability all good time not only, and in life-time service process, because of gravity deformation, thus the work-ing life of product can not be extended, contribute to the popularization of wide model.
The technical solution adopted in the present invention is: a kind of building water supply PVC-U pipe fitting, and the formula of described building water supply PVC-U pipe fitting is made up of the raw material of following deal:
Polyvinyl chloride resin (S-700): 100
OM-71OS：2
ESO ：3
ACR-401 ：3
CPE-135A：7
CaCO3：6
Titanium dioxide: 1.5
ZB-60：0.5。
In the present invention: a kind of production technique of building water supply PVC-U pipe fitting, comprises the following steps:
The first step, batching: first check before batching that whether various starting material outward appearance is normal, have impurity or contaminated
Raw material can not use, the moisture absorption caking to dry, sieve, various ready starting material are pressed recipe requirements weighing;
Second step, kneading: kneading pot is heated to about 90 DEG C, stop heating, starts kneader, by suitable
Sequence is fed in raw material, and first adds polyvinyl chloride resin, stablizer, lubricant and filler successively; Stir 4 ~ 6 minutes, more slowly add softening agent, after softening agent is absorbed completely, add CPE and ACR, continue stirring and compound was drawn off from kneader in 5 minutes, cool stand-by; Kneaded powder requires without conglomeration, jaundice and sends out the phenomenons such as burnt;
3rd step, granulation: be that 140-150 degree heats by head temperature by extruding granulator, after temperature reaches permanent 30 minutes again, granulation of can feeding in raw material, the pellet made is evenly closely knit and without adhesion, maximum particle diameter is no more than 5mm, and length is no more than 6mm;
4th step, injection moulding: although be added with various processing aid in PVC-U, but mobility is still poor, during injection moulding, for overcoming the friction resistance in flow process, avoid flow velocity to produce excessive heat of friction and melt fracture soon again, thus need the slightly high point of injection pressure, injection speed is slightly a little slower, by constantly groping, desirable injection pressure general control 7.5 ~ 10Mpa;
5th step, finishing: tested by the product after injection moulding, repair undesirable for inspection;
6th step, product warehousing: by the packing of product warehouse-in be up to the standards.
After adopting technique scheme, beneficial effect of the present invention is: the building water supply PVC-U pipe fitting made by this complete processing, there is low-temperature flexibility, rigidity, ring stiffness and creep resisting ability all good time not only, and in life-time service process, can not because of gravity deformation, thus extend the work-ing life of product, contribute to the popularization of wide model.
