Abstract

The invention discloses a preparation method of a cold-resistant hot melt adhesive, and relates to the technical field of hot melt adhesives. The method comprises the following steps that polyethylene wax is put into a mixer for heating and melting, surplus materials are added into the mixer, heating is conducted to 140 DEG C, and stirring is conducted for 1 h to 2 h at 200 rmp to 300 rmp; the mixed materials which are stirred to be uniform are subjected to extrusion pelletization through an extruder, the heating temperature of a machine barrel is set to range from 158 DEG C to 185 DEG C, the rotating speed of a screw is set to range from 350 rpm to 500 rpm, after the materials are extruded, cooling is conducted through a water channel, cutting is conducted, and the cold-resistant hot melt adhesive is obtained. According to the preparation method of the cold-resistant hot melt adhesive, the problems that an existing hot melt adhesive is poor in cold resistance and prone to brittle rupture at low temperature, and the viscosity is decreased are solved.

Description

The preparation method of Cold-resistant hot melt adhesive
Technical field
The present invention relates to PUR technical field, the preparation method of a kind of Cold-resistant hot melt adhesive.
Background technology
PUR is that one is at room temperature usual in solid-state, after adding heat fusing, and coated and that material is bonded together plasticity adhesive.PUR is environment-friendly products, and it is more superior than the performance of white glue with vinyl, and its curing rate has preferable adhesive strength and pliability soon, and bonded object is extensive, if timber, paper, fiber, metal, plastics, rubber etc. carry out bonding.But, existing PUR cold tolerance is poor, is susceptible to embrittlement at low temperatures, and viscosity reduces, and weakens the bond strength of material.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of Cold-resistant hot melt adhesive, this can to solve existing PUR cold tolerance poor, is susceptible to embrittlement, and the problem that viscosity reduces at low temperatures.
In order to solve the problems referred to above, the technical solution used in the present invention is: the preparation method of this Cold-resistant hot melt adhesive uses the raw material making of following parts by weight to constitute: ethylene-methacrylic acid copolymer 72 parts, methyl parahydroxybenzoate 10 parts, Aromatic Petroleum Resins 8 parts, Tissuemat E 15 parts, dioctyl phthalate 2 parts, nano-calcium carbonate 5 parts, 0.3 part of antioxidant；Preparation comprises the following steps: Tissuemat E is put into batch mixer heating and melting, is added by leftover materials in batch mixer, is warming up to 140 DEG C, stirs 1～2 hour under conditions of 200～300rmp；The mixed material extruder extruding pelletization that will stir, sets barrel heat temperature as 158～185 DEG C, and screw speed is, and 350～500rpm, cool down blank through tank after material extrusion, to obtain final product.
In the technical scheme of the preparation method of above-mentioned Cold-resistant hot melt adhesive, more specifically technical scheme is it may also is that described extruder is double screw extruder, and screw slenderness ratio is 38, and feed rate is 30～60rpm.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that PUR cold tolerance is good, is not susceptible to embrittlement at low temperatures, and viscosity is high, and the bond strength of material is high；Using ethylene-methacrylic acid copolymer and methyl parahydroxybenzoate that the cryogenic property of PUR can be made to be effectively improved, low temperature flexibility can arrive-45 DEG C and not rupture, and peel strength is 8～12N/mm；Use tackifying resin can increase initial bonding strength and permanent adhesive intensity, reduce the melt viscosity of PUR, improve by the wellability of viscous material, improve operating characteristics；Use Tissuemat E scalable melt viscosity, improve mobility, increase case hardness, and accelerate curing rate；Use dioctyl phthalate can improve toughness and the tolerance to cold of PUR；Nano-calcium carbonate can reach preferably to disperse and interface interaction, and matrix is produced significant activeness and quietness effect；Expressing technique the toughness that can increase PUR is set.
